How do I write a system of equations

Answers

Answer 1
So for a word problem I assume you must first define your variables. Ask yourself what is the question asking and how could the question be answered with what you know through relationships that the problem defines. For example if the problem says that the total of a few thing is a number put that in as one of your equations. Examine how relationships like if there is half the amount of variable A than variable B work and figure out how to write that as an equation that makes sense. To double check if you wrote your equations correctly double check the information given in the problem and mentally sound out the equation. Hope this helps and note there are as many equations as there are variables in your system.

Suppose a normal distribution has a mean of 98 and a standard deviation of 6. What is P(x is greater than or equal to 86)? A. 0.16 B. 0.475 C. 0.84 D. 0.975

Answers

Answer

0.975 is the probability value

Step-by-step explanation:

We start by getting the z score of 86

z-score = (x - mean)/SD

z-score = (86-98)/6 = -12/6 = -2

So we want to find the probability of z greater than or equal to 2

We shall be using the standard normal distribution table here

I need help solving for x

Answers

To solve for x, bring the variable to one side, and bring all the remaining values to the other side by applying arithmetic operations on both sides of the equation. Simplify the values to find the result.

What Does Solve for x Mean?

Let's begin with a straightforward equation: x + 2 = 7.

How do you obtain X on your own?

Take away two from both sides.

⇒ x + 2 - 2 = 7 - 2\s⇒ x = 5

Check the solution, x = 5, by reentering it into the equation. We get 5 + 2= 7.

A rectangle has the dimensions 2. 4 x 2. 2. If I want a rectangle that has the area

16 times the size of the original rectangle, what will be my new dimensions?

New dimensions:

Answers

The new dimensions of the rectangle will be 4.8 x 4.4.

To find the new dimensions, we need to find the area of the original rectangle (2.4 x 2.2 = 5.28), and then multiply it by 16 to find the desired new area (5.28 x 16 = 84.48).

Since the area of a rectangle is determined by the product of its length and width, we can find the new dimensions by taking the square root of the new area and dividing it by the original length.

So, √84.48/2.4 = 4.4 and √84.48/2.2 = 4.8.

These are the new dimensions of the rectangle.

We have to make sure that the new dimensions are in the same proportion as the original one, we can use the same factor of multiplying to get the new length and width.

If a rectangular plot measures 33 feet by 44 feet, what is

Answers

Answer:

55 feet

Step-by-step explanation:

If you draw it out, the diagnonal along wiht 2 sides of the rectangle make a rigth angles traingle.

Using pythagoras theoreom, [tex]c^{2} =a^{2} +b^{2}[/tex], c is the length of the diagonal and a and b are 2 sides of rectangle.

So c=[tex]\sqrt{a^{2} +b^{2} }[/tex]

=[tex]\sqrt{33^{2} +44^{2} }[/tex]

put in alculator and get:

55

=55 feet

The measure of the diagonal of the rectangle plot which has the measure of 33 feet by 44 feet is 55 feet.

What is the diagonal of the rectangle?

The diagonal of the rectangle is the distance from opposite vertices of it. There are two diagonals in a rectangle which are equal in measure.

To find the diagonal of the rectangle, the following formula is used.

[tex]d=\sqrt{l^2+w^2}[/tex]

Here, (l) is the length of the rectangle and (w) is the width of it.

The width of the rectangular plot measures 33 feet and length measure 44 feet. Plug in these values in the above formula to find the diagonal of the plot.

[tex]d=\sqrt{(44)^2+(33)^2}\\d=\sqrt{1936+1089}\\d=\sqrt{325}\\d=55\rm\; ft[/tex]

Hence, the measure of the diagonal of the rectangle plot which has measure of 33 feet by 44 feet is 55 ft.

To show my thinking, I will use the distributive property to simplify the expression.

5 = (1/2 x 1/1/20) + (²/3 + 2/1/1/0 4)

= (1/2 x 1/1/20) + (1/2 x 4)

= (1/2 x 1/1/20) + (1/2 x 4/1) ÷ 4

= (1/2 x 1/1/20 ÷ 4) + (1/2 x 4/1 ÷ 4)

= (1/2 x 1/4/80) + (1/2 x 1/4)

= (1/8 x 1/80) + (1/8)

What is a linear equation?

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

From the graph, the y-intercept of the line represents the value of the loan initially.

From the graph, the slope of both lines is negative, then the rate of change of the function will be negative.

Let 'x' be the number of months and 'y' be the amount owed.

The two points are (0, 560) and (1, 480). Then the equation of the line is given as,

(y - 560) = [(560 - 480) / (0 - 1)](x - 0)

y - 560 = - 80x

y = - 80x + 560

The given expression is  √(3y²)

Recall that to take out a factor out of the square root that factor must have a degree in multiple of 2 such as x², x⁴, (x-2)⁴, thus,

√(3y²)  = √3y²

On a coordinate plane, a line goes through (negative 12, negative 2) and (0, negative 4). A point is at (0, 6).Which point is on the line that passes through (0, 6) and is parallel to the given line? (–12, 8) (–6, 6) (2, 8) (6, 0)

Answers

Point (-12 , 8) is on the line that passes through (0, 6) and is parallel to the given line.

What is Equation of line?

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Since, We know that;

Parallel lines have same slopes and different y-intercepts

The formula of the slope of a line which passes through points (x₁ , y₁) and (x₂, y₂) is,

⇒  m = (y₂ - y₁) / (x₂ - x₁)

Since, The given line passes through points (-12 , -2) and (0 , -4)

Hence, Use the formula of the slope above to find the slope of the given line as;

⇒ m = (y₂ - y₁) / (x₂ - x₁)

⇒ m = (-4 - (-2)) / (0 - (-12))

⇒ m = (-2) / 12

⇒ m = - 1/6

Since, The two lines are parallel.

Hence, Their slopes are equal

So, The slope of the parallel line = - 1/6

Here, The parallel line passes through point (0 , 6)

Since, The form of the linear equation is y = mx + b, where m is the slope and b is the y-intercept.

⇒ m = -1/6 and b = 6

Hence, The equation of the parallel line is,

⇒ y =  x + 6

Now, Let us check which point is on the line by substitute the x in the equation by the x-coordinate of each point to find y, if y is equal the y-coordinate of the point, then the point is on the line as;

Point (-12 , 8)

Substitute x = -12 and y = 8

⇒ y =  (-12) + 6

⇒ y = 2 + 6 = 8

Clearly, The value of y is equal the y-coordinate of the point.

So, Point (-12 , 8) is on the line.

Exponential graph is identified by its curve.

An exponential graph is a graph that shows a rapid increase or decrease of a value over time, where the rate of change is proportional to the current value. It is usually represented by a curve that bends upward or downward.

The key characteristic of an exponential graph is that the Y-axis is on a logarithmic scale, and the curve of the graph is a steep curve going either up or down. The equation of an exponential graph is usually of the form y = ab^x, where a is the initial value, b is the growth or decay factor, and x is the independent variable.
