Which system of inequalities is represented by the graph?
The following system of inequalities is represented by the graph
x+y>3
-x+y< -4
What is inequality?
An inequality in mathematics depicts the connection between two values in an algebraic statement that are not equal. One of the two variables on the two sides of the inequality may be greater than, greater than or equal to, less than, or less than or equal to another value, according to inequality signals.
Consider the inequalities:
x+y>3-------(1)
-x+y< -4------(2)
Find x and y intercepts of both by considering them as equations by using equal sign in the place of inequality sign
x+y=3-------(3)
-x+y= -4------(4)
Find x and intercepts of these 2 equations:
we get x intercept when y=0 ( substitute y=0 into the respective equations and find x)
we get y intercept when x=0 ( substitute x=0 into the respective equations and find y)
x intercept of (3) is (3,0)
y intercept of (3) is (0,3)
x intercept of (3) is (4,0)
y intercept of (3) is (0,-4)

Select the graph of the solution set that would represent the following expression. 3(x - 2) = 5(x + 1)
Answer:
Step-by-step explanation:
To graph the equation 3(x - 2) = 5(x + 1), we can first simplify it by expanding the brackets:
3x - 6 = 5x + 5
Next, we can isolate the variable on one side of the equation. We can do this by subtracting 3x from both sides and adding 6 to both sides:
-11 = 2x
x = -11/2
Now we have the x-coordinate of the point where the graph of the equation intersects the x-axis. To find the y-coordinate of this point, we can substitute x = -11/2 into one of the original equations and solve for y:
3(x - 2) = 5(x + 1)
3(-11/2 - 2) = 5(-11/2 + 1)
-33/2 - 6 = -55/2 + 5
-33/2 - 6 + 55/2 = 5
-33/2 + 44/2 = 5
11/2 = 5
Question 4 Solve the inequality and write your answer in interval notation 16+12x<19x+12
The solution to the inequality 16 + 12x < 19x + 12 is all the values of x between the interval notation (4/7, ∞).
To solve the inequality 16 + 12x < 19x + 12, we need to isolate the variable x on one side of the inequality. We can do this by subtracting 12x from both sides and subtracting 12 from both sides:
16 + 12x - 12x - 12 < 19x + 12 - 12x - 12
4 < 7x
Solving for x, we can divide both sides by 7:
4/7 < x or x > 4/7
In interval notation, this would be (4/7, ∞). Therefore, the solution to the inequality is (4/7, ∞) in interval notation.

What is the largest possible value x could take given that it must be an integer? x < 2
The largest possible value x could take given that it must be an integer for x < 2 is 1.
Difference between an inequality and an equation?The key distinction between an inequality and an equation is that an inequality describes a connection of inequality between two expressions, whereas an equation expresses equality between two expressions. In other words, an inequality shows that one expression is more or less than the other expression, but an equation shows that two expressions have the same value.
The highest number x might have is 1 if x must be an integer and x 2. This is due to the fact that any number higher than one would break the inequality x 2, and any number between one and two that is not an integer would also violate the stipulation that x must be an integer.

What are Autoregressive (AR) models?Autoregressive (AR) models are a type of statistical model that uses the past values of a variable to predict its future values. The main assumption of AR models is that the future values of the variable are correlated with its past values. They are used to analyze time series data and are commonly used in forecasting, price and demand prediction, and other time-dependent processes.
The first model (a) is an ARMA(1,2) model, which is a combination of an autoregressive (AR) and a moving average (MA) model. This model is both causal and invertible. Causal models are models that have a lag of only one period, while invertible models are those that have a lag of two or more periods. The second model (b) is an ARMA(2,1) model, which is a combination of an autoregressive (AR) and a moving average (MA) model. This model is both causal and invertible.

Therefore , the solution of the given problem of equation comes out to be which is (x, y) = (-60/17, 58/17).
How do mathematics equation work?The same letter is frequently used in mathematical formulas to attempt to enforce unity between two claims. Mathematical expression equations, also referred to as assertions, are used to demonstrate the equality of many academic figures. Using y + 6 = 12 like an example, the normalise separates 12 but rather b + 6 in to the two pieces. The relationship between each sign variable and the amount of lines can be identified. A symbol's meaning typically runs counter to itself.
Here,
Elimination is one approach that could be used to solve the problem. So that the component of y in each equation is -12, we can do this by multiplying the first equation by 4 and the second equation by 3:
=> 4(2x + 3y = -6) -> 8x + 12y = -24
=> 3(3x - 4y = -12) -> 9x - 12y = -36
The two formulae combined give us:
=> 8x + 12y + 9x - 12y = -24 - 36
=> 17x = -60
=>x = -60/17
We can find y by substituting x into either equation:
=> 2(-60/17) + 3y = -6
=> 3(-60/17) - 4y = -12
When we simplify each solution, we obtain:
=> -120/17 + 3y = -6
=>-180/17 - 4y = -12
By y in each solution and solving, we obtain:
=> 3y = 174/17
=> y = 58/17
As a result, there is only one solution to the system, which is (x, y) = (-60/17, 58/17).

7. A realtor took $32,500 made on the sale of a home and placed it in a new account that earns
6% compounded annually. Find the total amount in the account after 5 years.
Please help!
Answer: The amount is $43492.35 and the interest is $10992.35.
Step-by-step explanation:
To find amount we use formula:
A = P(1+r/n)^nt
A = total amount
P = principal or amount of money deposited,
r = annual interest rate
n = number of times compounded per year
t = time in years
In this example we have
P=32,000 , R=6% , N = 1 T= 5 YEARS
After plugging the given information we have
A=32000(1+0.06/1)^1.5
A=32500*1.06^5
A=32500*1.338226
A=$43492.35
To find interest we use formula A=P+I , since A= 43492.35 P =32500 we have:
A=P+I
$43492.35 = 32500+I
I=$43492.35-32500
I=$10992.35

what is expression ?Mathematical operations include doubling, dividing, adding, and subtracting. A phrase is constructed as follows: Expression, monetary value, and mathematical operation Numbers, parameters, and functions make up a mathematical expression. It is possible to use words and terms in contrast. Every mathematical statement including variables, numbers, and a mathematical operation between them is called an expression, sometimes referred to as an algebraic expression. For example, the expression 4m + 5 is composed of the expressions 4m and 5, as well as the variable m from the above equation, which are all separated by the mathematical symbol +.
In the formula, h is the height, t is the time, and a and b are the parameters that need to be approximated.
The information in the table may be used to estimate the values of a and b. The equation is first transformed to yield:
[tex]log(b*t) = log(h/a)[/tex]
[tex]19 = 19.24 * log(53.89*t)[/tex]
t = 0.186 months, or approximately 5.58 days, or log(53.89*t) = 1 53.89*t = 10
Hence, 5.58 days is the best guess for the age of the plant at 19 inches tall. Seeing that this is a very little period of time, it is probable that the model will not be correct for values of t this low. Moreover, we should evaluate the model's goodness of fit and take into account additional elements that can influence plant development.

List the interval (a,b) where the f(x) is increasing.
At what x-value does f(x) have a relative maximum?
(a) The function is decreasing at x=2.
(b) The interval where f(x) is increasing is (-3, 3).
(c) The function, f(x) has a relative maximum at x=-3.
Is the function increasing or decreasing at x=2?
To determine whether the function is increasing or decreasing at x=2, we need to find the derivative of f(x) and evaluate it at x=2.
f(x) = x³ - 27x + 5
f'(x) = 3x² - 27
At x=2, f'(2) = 3(2)² - 27 = -15, which is negative.
Therefore, the function is decreasing at x=2.
To find the interval where f(x) is increasing, we need to find the values of x where f'(x) > 0.
f'(x) = 3x² - 27
3x² - 27 > 0
3(x² - 9) > 0
(x - 3)(x + 3) > 0
The critical points are x=-3 and x=3.
We can test each of the intervals created by these critical points to see where f(x) is increasing or decreasing.
When x < -3, f'(x) < 0, so f(x) is decreasing.
When -3 < x < 3, f'(x) > 0, so f(x) is increasing.
When x > 3, f'(x) > 0, so f(x) is increasing.
Therefore, the interval where f(x) is increasing is (-3, 3).
To find the relative maximum of f(x), we need to find the critical points where f'(x) = 0.
3x² - 27 = 0
x² - 9 = 0
(x - 3)(x + 3) = 0
The critical points are x=-3 and x=3.
To determine which of these critical points corresponds to a relative maximum, we need to use the second derivative test.
f''(x) = 6x
At x=-3, f''(-3) = -18, which is negative.
Therefore, f(x) has a relative maximum at x=-3.

As a result of the cylinder's volume being 12,566.4 centimetres³ and its height being 8 cm, the surface area of the cylinder is approximately 942.5 cm².
what is volume ?
Volume in mathematics refers to how much room a three-dimensional object takes up. It is a way to quantify how much enclosed room there is overall in a solid figure. Depending on the shape of the item, a number of formulas can be used to calculate its volume. A rectangular prism's volume, for instance, can be calculated by multiplying its length, breadth, and height, whereas a cylinder's volume can be calculated by dividing its base area by its height. The system being used will determine the unit of measurement for volume, but typical units include cubic metres (m³) and cubic centimetres (cm³).
given
a) V = πr²h, where V is the volume, r is the radius, and h is the height, is the expression for a cylinder's volume. By rearranging the calculation, we can find r:
V/(h) = √12,566.4/(*8)) Equals r ≈ 10 centimetres (rounded to the closest tenth of a cm) (rounded to the nearest tenth of a cm)
Consequently, the cylinder's radius is roughly 10 centimetres.
b) The equation A = r² determines the area of a cylinder's base. Using the r number we just discovered, we have:
A = π(10)² ≈ 314.2 cm² (rounded to the closest tenth of a cm) (rounded to the nearest tenth of a cm)
Consequently, the cylinder's base has a surface area of about 314.2 cm².
c) The equation L = 2πrh, where r is the radius and h is the height, determines the lateral area of a cylinder. With the numbers from the problem substituted, we obtain:
L = 2π(10)(8) ≈ 502.7 cm² (rounded to the closest tenth of a cm) (rounded to the nearest tenth of a cm)
Consequently, the cylinder's side area is roughly 502.7 cm².
d) The equation S = 2πr² + 2πrh gives the surface area of a cylindrical. Using the r and h numbers we discovered earlier, we have:
S = 2π(10)² + 2π(10)(8) ≈ 942.5 cm² (rounded to the nearest tenth of a centimetre) (rounded to the nearest tenth of a cm)
As a result of the cylinder's volume being 12,566.4 centimetres³ and its height being 8 cm, the surface area of the cylinder is approximately 942.5 cm².

According to the given equation, a+x=b+y=c+z+1, where a,b,c,x,y, z are non-zero distinct real numbers, we can rearrange the equation to find the value of one of the variables in terms of the others. For example, we can rearrange the equation to find the value of x in terms of the other variables:

Similarly, we can rearrange the equation to find the value of y and z in terms of the other variables:
y = a+x-b = c+z+1-b
z = a+x-c-1 = b+y-c-1
Now, we can substitute these values into the given matrix to find the value of each element:

Let X (3, 0.02). Given Tx = 300 calculated by the Esscher Premium Principle with parameter 1, calculate h
The value of h is 99.969.
The Esscher Premium Principle is a method of calculating insurance premiums that considers the risk of an event occurring and the potential severity of the loss. The formula for the Esscher Premium Principle is:
Ex = ln(∑eαx Px)/α
Where Ex is the Esscher premium, α is the parameter, x is the loss amount, and Px is the probability of the loss occurring.
In this case, we are given X (3, 0.02), meaning that the loss amount is 3 and the probability of the loss occurring is 0.02. We are also given that the Esscher premium is 300 and the parameter is 1. Plugging these values into the formula, we get:
300 = ln(∑e1(3) 0.02)/1
Simplifying the equation, we get:
300 = ln(0.02e3)
Taking the natural logarithm of both sides, we get:
e300 = 0.02e3
Dividing both sides by 0.02, we get:
e300/0.02 = e3
Taking the natural logarithm of both sides again, we get:
300 - ln(0.02) = 3
Solving for h, we get:
h = (300 - ln(0.02))/3
h = 99.969
Therefore, the value of h is 99.969.

what is the quadratic formula multiplied by pie divided by X?
The quadratic formula multiplied by π divided by x is: π(-b ± √(b² - 4ac)) / (2ax).
What is the Quadratic formula?
The quadratic formula is used to solve quadratic equations, and is given by: x = (-b ± √(b² - 4ac)) / 2a.
Pi otherwise denoted by the symbol π in real terms is a mathematical constant that represents the ratio of the circumference of a circle to its diameter. It is approximately equal to 3.14159, although its decimal representation goes on infinitely without repeating.
Since the rational objective of every mathematical expression or problem is to simplify, we will leave Pi in it's symbolic form - π.
Thus, multiplying quadratic formula by π and dividing by x, we get:
π(-b ± √(b² - 4ac)) / (2ax)

The requried combined length of both trains is 900 meters or 900 km.
What is speed?Speed is defined as when an object is in motion, the distance covered by that object per unit of time is called speed.
Here,
Let's first convert the given speeds from km/h to m/s to make the calculations easier.
Speed of the first train = 102 km/h = (102 x 1000) m/3600 s = 28.33 m/s
Speed of the second train = 30 km/h = (30 x 1000) m/3600 s = 8.33 m/s
Now, let's consider the relative speed of the two trains since they are moving in the same direction:
Relative speed = Speed of first train - Speed of second train
= 28.33 - 8.33
= 20 m/s
Let's assume that the length of the first train is x m and the length of the second train is y m.
Distance covered by first train in 45 seconds = (x + y) m
Speed of first train = Distance covered by first train / Time taken
= (x + y) / 45 km/s
We know that the speed of the first train is 20 m/s. So, we can write:
20 = [(x + y) / 45]
Solving for (x + y),
x + y = 900 m
Therefore, the combined length of both trains is 900 meters or 900 km.

John has a jar filled with juice. After he poured 350 ml of juice in each 8 glasses he was still left with 200 ml juice in the jar. What was the capacity of jar in liters?
Step By Step Explanation
Filled jar = ?
How much poured or (x) = 350ml × 8 glasses
=2800 ml
How much left or (y) = 200ml
Capacity = How much poured + How much left
Capacity = x + y
Capacity = 2800 ml + 200 ml
Capacity = 3000ml
Give answer in litres
1 litre = 1000 millilitre
So 3000ml = 3000 ÷ 1000
So 3000 ml = 3 litres
Capacity = 3 litres
2. (4 marks) Find a basis for \( \mathbb{R}^{4} \) containing \( v=(1,-1,1,-1), \quad w=(0,1,0,1) \).
A basis for \( \mathbb{R}^{4} \) containing \( v \) and \( w \) is \( \{v, w, e_{1}, e_{2}\} = \{(1,-1,1,-1), (0,1,0,1), (1,0,0,0), (0,1,0,0)\} \).
A basis for \( \mathbb{R}^{4} \) is a set of four linearly independent vectors that span \( \mathbb{R}^{4} \). We are given two vectors \( v=(1,-1,1,-1) \) and \( w=(0,1,0,1) \) that are part of the basis. To find the other two vectors, we can use the standard basis vectors \( e_{1}=(1,0,0,0) \) and \( e_{2}=(0,1,0,0) \) and check if they are linearly independent with \( v \) and \( w \).
First, we check if \( e_{1} \) is linearly independent with \( v \) and \( w \). We can do this by setting up the equation \( a_{1}v + a_{2}w + a_{3}e_{1} = 0 \) and solving for the coefficients \( a_{1}, a_{2}, \) and \( a_{3} \).
\( a_{1}(1,-1,1,-1) + a_{2}(0,1,0,1) + a_{3}(1,0,0,0) = (0,0,0,0) \)
This gives us the system of equations:
\( a_{1} + a_{3} = 0 \)
\( -a_{1} + a_{2} = 0 \)
\( a_{1} = 0 \)
\( -a_{1} + a_{2} = 0 \)
We can see that the only solution is \( a_{1}=a_{2}=a_{3}=0 \), which means that \( e_{1} \) is linearly independent with \( v \) and \( w \).
Next, we check if \( e_{2} \) is linearly independent with \( v \), \( w \), and \( e_{1} \) by setting up the equation \( a_{1}v + a_{2}w + a_{3}e_{1} + a_{4}e_{2} = 0 \) and solving for the coefficients \( a_{1}, a_{2}, a_{3}, \) and \( a_{4} \).
\( a_{1}(1,-1,1,-1) + a_{2}(0,1,0,1) + a_{3}(1,0,0,0) + a_{4}(0,1,0,0) = (0,0,0,0) \)
This gives us the system of equations:
\( a_{1} + a_{3} = 0 \)
\( -a_{1} + a_{2} + a_{4} = 0 \)
\( a_{1} = 0 \)
\( -a_{1} + a_{2} = 0 \)
Again, we can see that the only solution is \( a_{1}=a_{2}=a_{3}=a_{4}=0 \), which means that \( e_{2} \) is linearly independent with \( v \), \( w \), and \( e_{1} \).
Therefore, a basis for \( \mathbb{R}^{4} \) containing \( v \) and \( w \) is \( \{v, w, e_{1}, e_{2}\} = \{(1,-1,1,-1), (0,1,0,1), (1,0,0,0), (0,1,0,0)\} \).
