solve for b: 4 1/3b+b=6b–10.4
Answer:
-7 8/10 = b
Step-by-step explanation:
Rewrite 4 1/3b as (11/3)b, and rewrite 10.4 as 104/10. Then we have:
(11/3)b + b = 6b - 104/10.
This simplifies to b( (11/3) + 1 - 6) = 104/10, or
b(11/3 - 15/3) = 104/10, or
b( -4/3 ) = 104/10
Multiplying both sides by -3/4 isolates b, as desired:
-3(104)
(-3/4)(-4/3)b = -------------
4(10)
Then b = -312/40, or -156/20, or -78/10, or -7 8/10 = b
The value of b from the expression given will be b= -7 8/10 .
What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
We have been given an expression as;
4 1/3b + b = 6b–10.4
Rewrite 4 1/3b as (11/3)b, and rewrite 10.4 as 104/10, Then we have:
(11/3)b + b = 6b - 104/10.
This simplifies as;
b( (11/3) + 1 - 6) = 104/10, or
b(11/3 - 15/3) = 104/10, or
b( -4/3 ) = 104/10
Multiplying both sides by -3/4 isolates b, as desired:
-3(104)
(-3/4)(-4/3)b = -4(10)
Then b = -312/40,
or -156/20,
or -78/10,
or -7 8/10 = b
Therefore the value of b from the expression given will be b= -7 8/10 .

100 POINTS!The number of pizzas sold in one weekend at Pete's Pizzas is shown. Pie chart of pizza sales. Data includes: 130 hamburger, 175 pepperoni, 60 cheese, and 35 veggie. a) If Pete's sales remain consistent, how many pepperoni pizzas will he have sold when the total number of pizzas sold reaches 1600? b) How would the circle graph be different if Pete had sold 200 pepperoni pizzas, 100 hamburger pizzas, 50 veggie pizzas, and 50 cheese pizzas?
Answer:
A) [tex]\boxed{\sf 700 \ pepperoni \ pizzas}[/tex]
B) See the attached file!
Step-by-step explanation:
Total pizza sales in the pie chart = 175+60+35+130
=> 400 total Pizzas
Out of these 400, there are 175 pepperoni pizzas
So,
Pepperoni Pizzas = 175/400 = 7/16 (Simplest form)
So,
Among 1600 pizzas, pepperoni pizzas would be:

Which equation represents the vertical asymptote of the graph? a curve asymptotic to y equals 0 from negative x to negative y near x equals 12. A curve asymptotic to y equals 0 from positive x to positive y near x equals 12. x = 0 y = 0 x = 12 y = 12
Answer:
The correct option is x = 12
Step-by-step explanation:
An asymptote of a function is a line to to which the function converges to as it tends to infinity such that the function gets infinitesimally close to its asymptote but the function will not reach or cross its asymptote. That is the separating distance between the function and the asymptote tends to zero as either the x or y coordinates, or both the x and y coordinates tend to infinity.
A vertical aymptote, is one parallel to the y-axis and it is given by the value of the x-coordinate where it occurs
In the graph of the question, the vertical asymptote occurs at x = 12 and it is the line x = 12.
From the given graph, it can be said that the vertical asymptote will be formed at x=12. Option C is correct.
The given curve represents a function which is defined for all value fo x except 12.
The following information can be extracted from the graph of the function;
The function is defined for all values of x except 12.The function has a horizontal asymptote at y=0.The function forms a vertical asymptote at x=12. The curve approaches negative infinity from the left of 12 and approaches positive infinity from right of 12.Based on the above conclusions, it can be said that the vertical asymptote will be formed at x=12. Option C is correct.

Max and Sven bike away from home in the same direction starting at noon. They bike at constant speeds. Max bikes at xmph and he is ymph faster than Sven. By 4pm, how far ahead of Sven would Max be?
Answer:
Max would be 4y meters ahead by 4pm
Step-by-step explanation:
What we want to calculate here is the difference in the distance they have covered by 4pm given the speed at which they traveled.
Mathematically, distance = speed * time
The time is just the difference between 12 noon and 4pm which is 4 hours
Let’s tackle Max’s
He’s biking at x km/h, so the distance he would have covered by 4pm would be 4 * x = 4x meters
Now let’s tackle Sven
Sven is biking at a speed which is y mph less than Max’s x mph
Thus his speed would be (x-y) mph
His distance covered would be 4(x-y) meters
Now the difference between their bikes distance at 4pm would be;
4x - [4(x-y)]
= 4x -(4x -4y)
4x -4x + 4y
= 4y
Hence, Max would be 4y meters ahead by 4pm
By 4 pm, Max would be 4y meters far ahead of Sven.
What is the distance?Distance is defined as the product of speed and time.
distance = speed × time
To determine the difference in the distance they have covered by 4 pm given the speed at which they traveled.
Given that, Max and Sven bike away from home in the same direction starting at noon
The time is the difference between the 4 hours between noon and 4 o'clock.
Max's current speed of x km/h,
The distance he would have traveled by 4 pm as
⇒ 4 × x
⇒ 4x meters
Max is biking at x mph while Sven is going y mph slower.
Max would therefore be going at (x-y) mph.
Max's distance covered would be 4(x-y) meters
At 4 p.m., the distance between their bikes would be as:
⇒ 4x - [4(x-y)]
⇒ 4x -(4x -4y)
⇒ 4x -4x + 4y
⇒ 4y
Hence, By 4 pm, Max would be 4y meters far ahead of Sven.

The total cost f(x), in dollars, for renting a car for a day and driving it x miles is shown: f(x) = 90 + 0.11x What does f(30) represent?
Answer:
f(30) represents the total cost when the car is driven 30 miles
Step-by-step explanation:
f(30) is the y value when x= 30
Since x represents miles, f(30) is the y value of the function when you drive a car 30 miles, basically how much it will cost.
We solve this by plugging 30 in for x:
f(30)= 90 + 0.11(30)
f(30)= 90 + 3.3
f(30)= 93.3
Thus, renting a car for a day and driving it 30 miles costs $93.30

Christine will rent a car for the weekend. She can choose one of two plans. The first plan has no initial fee but costs $0.60 per mile driven. The second plan has
an initial fee of $50 and costs an additional $0.40 per mile driven. How many miles would Christine need to drive for the two plans to cost the same?
Answer:
Christine needs to drive 250 miles for the two plans to cost the same
Step-by-step explanation:
For answering the question correctly and helping Christine, we will use the following equation:
x = number of miles driven
Cost of the first plan = 0.60x
Cost of the second plan = 50 + 0.40x
How many miles would Christine need to drive for the two plans to cost the same?
Cost of the first plan = Cost of the second plan
0.60x = 50 + 0.40x
0.60x - 0.40x = 50 (Subtracting 0.40x at both sides)
0.20x = 50
x = 50/0.2
x = 250 miles driven
Christine needs to drive 250 miles for the two plans to cost the same.
Question below. Please answer it, its math.
Answer:
- 0.8
Step-by-step explanation:
The first thing we want to do here is simplify the expression -
[tex]\frac{3}{5}[/tex]( 2x + 5 ) - 2x, Distribute the " [tex]\frac{3}{5}[/tex] " to elements within the parenthesis
= [tex]\frac{3}{5}[/tex] [tex]*[/tex] 2x + [tex]\frac{3}{5}[/tex] [tex]*[/tex] 5 - 2x, Focus on simplifying the expression " [tex]\frac{3}{5}[/tex] [tex]*[/tex] 2x + [tex]\frac{3}{5}[/tex] [tex]*[/tex] 5 "
= [tex]2\cdot \frac{3}{5}x+5\cdot \frac{3}{5}[/tex] - 2x
= [tex]\frac{6x}{5}+3[/tex] - 2x, Combine fractions
= [tex]-\frac{4x}{5}[/tex] + 3
= [tex]-\frac{4}{5}[/tex]x + 3
So we have our simplified expression " [tex]-\frac{4}{5}[/tex]x + 3, " with [tex]-\frac{4}{5}[/tex] being the coefficient of x. Our requirements are that this fraction should be expressed as a decimal, so we can simply divide the numerator by the denominator to figure that out,
- 4 / 5 = - 0.8,
Solution = - 0.8
In the figure below, B is the center of the circle. NL= 28, OS = 4x-2, RB = 22 and SB = 22. Find the value of x.
Explanation:
RB and SB are 22 units. Since they are both equal, this means the chords NL and OQ are the same length. This is true whenever the chords are the same distance away from the center.
NL = 28, so OQ = 28 as well.
Furthermore, the radius BP cuts chord OQ in half (because BP is perpendicular to OS), which means OS = 28/2 = 14. We are also told that OS = 4x-22
Therefore,
4x-22 = 14
4x = 14+22
4x = 36
x = 36/4
x = 9
5x-2y = -25 Solve by linear combination please show work
Answer:
The answer you get is x=-3, and y=5 or (-3,5)
Step-by-step explanation:
3x+y=-4 and 5x-2y = -25.
Firstly, to solve the equation let's use the multiplication method.
5x-2y=-25 (Multiply by 1)
3x+y=-4 (Multiply by 2)
=
5x-2y=-25
+6x+2y=-8
=
11x=-33
x=-3
We know that x=-3, now we can find y by substituting this value into other equations.
5(-3)-2y=-25
-15-2y=-25
+15 +15
-2y=-10
y=5
The answer you get is x=-3, and y=5 or (-3,5)

Show your work and final equation in the space provided. partc-Now that you have determined the equation of the parabola, assume that x represents the number of seconds that have passed since the ball was thrown and determine approximately how long it will take for the ball to hit the ground.
Answer:
(a, b, c) = (-1/3, 2, 5)y = (-1/3)x^2 +2x +57.90 secondsStep-by-step explanation:
From your equations in Part A, we can write the matrix equation as ...
[tex]\left[\begin{array}{ccc}9&3&1\\25&5&1\\36&6&1\end{array}\right] \cdot\left[\begin{array}{c}a&b&c\end{array}\right] = \left[\begin{array}{c}8&\frac{20}{3}&5\end{array}\right][/tex]
For the purpose of finding the inverse matrix (which we don't really need to do to solve this), it is convenient to use an augmented matrix that will give both the matrix inverse and the solution.
[tex]\left[\begin{array}{ccc|ccc|c}9&3&1&1&0&0&8\\25&5&1&0&1&0&\frac{20}{3}\\36&6&1&0&0&1&5\end{array}\right][/tex]
For the first step in the solution, we'll divide the first row by 9, then subtract 25 times that from the second row, and 36 times that from the third row. The goal of this step is to make the first column be 1, 0, 0. The result is ...
[tex]\left[\begin{array}{ccc|ccc|c}1&\frac{1}{3}&\frac{1}{9}&\frac{1}{9}&0&0&\frac{8}{9}\\0&-\frac{10}{3}&-\frac{16}{9}&-\frac{25}{9}&1&0&-\frac{140}{9}\\0&-6&-3&-4&0&1&-27\end{array}\right][/tex]
For the second step in the solution, we'll multiply the second row by -3/10, then subtract 1/3 times that from the first row and add 6 times that to the third row. The goal of this step is to make the second column be 0, 1, 0. The result is ...
[tex]\left[\begin{array}{ccc|ccc|c}1&0&-\frac{1}{15}&-\frac{1}{6}&\frac{1}{10}&0&-\frac{2}{3}\\0&1&\frac{8}{15}&\frac{5}{6}&-\frac{3}{10}&0&\frac{14}{3}\\0&0&\frac{1}{5}&1&-\frac{9}{5}&1&1\end{array}\right][/tex]
For the third step in the solution, we'll multiply the third row by 5, then add 1/15 of that to the first row and -8/15 of that to the second row. The goal of this step is to make the third column be 0, 0, 1. The result is ...
[tex]\left[\begin{array}{ccc|ccc|c}1&0&0&\frac{1}{6}&-\frac{1}{2}&\frac{1}{3}&-\frac{1}{3}\\0&1&0&-\frac{11}{6}&\frac{9}{2}&-\frac{8}{3}&2\\0&0&1&5&-9&5&5\end{array}\right][/tex]
The middle section of this augmented matrix is the inverse of the coefficient matrix:
[tex]A^{-1}=\left[\begin{array}{ccc}\frac{1}{6}&-\frac{1}{2}&\frac{1}{3}\\-\frac{11}{6}&\frac{9}{2}&-\frac{8}{3}\\5&-9&5\end{array}\right][/tex]
The right section of the augmented matrix is the solution set:
[tex]X=\left[\begin{array}{c}a\\b\\c\end{array}\right]=\left[\begin{array}{c}-\frac{1}{3}\\2\\5\end{array}\right][/tex]

The ball will hit the ground when y=0. The values(s) of x can be found from the quadratic formula:
x = (-b±√(b²-4ac))/(2a) = (-2±√(2²-4(-1/3)(5)))/(2(-1/3))
x = (2 ± √(32/3))/(2/3) = 3±√24 = {-1.899, 7.899}
It will take about 7.90 seconds for the ball to hit the ground.

Answer:
Independent: Amount of hours she works
Dependent: Amount of money she makes
Step-by-step explanation:
The independent variable is the part of the equation that changes. In this case the only thing that changes is how long she works, the amount of money she charges and what she is doing does not change.
The dependent variable is what you measure in the equation. In this case, the amount of money she makes depends on the amount of time she works.

two quadratic functions are shown:
which function has lowest minimum value, and what are it's coordinates?
function 1 has the lowest minimum value and it's coordinates are (-1,4)
function 1 has the lowest minimum value and it's coordinates are (0,7)
function 2 has the lowest minimum value and it's coordinates are (-1,7)
function 2 has the lowest minimum value and it's coordinates are (0,3)
To find the minimum value of function 1, we need to find the vertex. The formula for the x-coordinate of the vertex is -b/2a, which is -1 in this equation. However, to find minimum and maximum values, we need to look at the y-coordinate. f(-1) is 4, which we know is a minimum (rather than a maximum), because the leading coefficient is positive -- so the parabola opens upwards. So, the minimum value of f(x) is 4, and the coordinate is (-1, 4).
From the table, the minimum value of g(x) is 3, and the coordinate is (0, 3).
Therefore, function 2 has the lowest minimum value, with coordinates (0, 3).

each and contain a whole number of apples. The weights are normally distributed
with a mean of 5 pounds and a standard deviation of 0.25 pound. An inspector
weighs each bag and rejects all bags that weigh less than 4.75 pounds. What
percentage of bags will the inspector reject? *
Your answer
Answer: The percentage of bags will the inspector reject = 15.87%
Step-by-step explanation:
Given, The weights of apple bags are normally distributed with a mean of 5 pounds and a standard deviation of 0.25 pound.
i.e. [tex]\mu=5[/tex] and [tex]\sigma=0.25[/tex]
Let X be the weight of any random apple bag.
Since an inspector weighs each bag and rejects all bags that weigh less than 4.75 pounds.
Then, the probability of bags will be rejected = probability that bags weigh less than 4.75 pounds.
[tex]=P(X<4.75)\\\\=P(\dfrac{X-\mu}{\sigma}<\dfrac{4.75-5}{0.25})\\\\=P(z<-1)\ \ \ [z=\dfrac{X-\mu}{\sigma}][/tex]
[tex]=1-P(z<1)\\\\=1-0.8413\ \ \ [\text{By z-value table}]\\\\=0.1587=15.87\%[/tex]
Hence, the percentage of bags will the inspector reject = 15.87%

What is the domain and range of each relation?
Drag the answer into the box to match each relation.
{(−7, 2), (−2, 2), (0, 1), (4, 5)}
A mapping diagram. Element x contains negative 4, negative 3, negative 1, and 1. Element Y contains negative 3, negative 1, and 4. Negative four maps to negative 1. Negative three maps to negative 3 and 4. Negative one maps negative 1. One maps to 4.
Answer:
See below.
Step-by-step explanation:
The domain of a relation are simply its x-values, while the range of a relation are its y-values.
1)
We have the relation:
{(-7,2), (-2,2), (0,1), (4,5)}
Again, the domain of this relation are the x-values. Therefore, the domain is:
{-7, -2, 0, 4}
The range of this relation are the y-values. Therefore, the range is:
{2, 1, 5}
Note that even though the 2 repeats, we only count it once because it's the same.
2)
We have the relation:
{(-4,-1), (-3,-3), (-3,4), (-1,-1), (1,4)}
The domain are the x-values. Therefore, the domain is:
{-4, -3, -1, 1}
Again, the -3 repeats so we only count it once.
And the range would be the y-values:
{-3, -1, 4}
It's customary to place them in ascending order.
Answer:
If there are two set A and B. All the elements of set A are called domain and all elements of set B are range.And element of B which are maping with set A elements are codomain
Step-by-step explanation:
domains are -7,-2,0,4
range are 2,1,5

Answer:
[tex]x=19[/tex]
Step-by-step explanation:
First, note that Angle X and angle Y are angles formed when two parallel lines are being cut by a transversal. This makes Angle X and Y consecutive interior angles. Consecutive interior angles are supplementary.
Therefore:
[tex](3x-5)+(90+2x)=180[/tex]
[tex]5x-5=90[/tex]
[tex]5x=95[/tex]
[tex]x=19[/tex]

Yvette likes to increase the distance she runs by 1% each day. If yesterday Yvette ran 10.75km, how much further is she going to run today?
｡☆✼★ ━━━━━━━━━━━━━━ ☾
The multiplier for 1% would be 1.01
Multiply her distance from yesterday by this value
new distance = 10.75 x 1.01
new distance = 10.8575
I'm assuming you'd want the answer to 2 d.p (however, you can round accordingly if needed otherwise)
Subtract the two values
10.8575 - 10.75 = 0.1075
So, to 2 d.p your answer would be 0.11 km
Have A Nice Day ❤

A train travels 60km in y minutes.If this average speed is 400km per hour,find the value of y
Answer:
9
Step-by-step explanation:
Speed of the train is:
60 km / y minAnd average speed is:
400 km / h = replacing 1 h with 60 min400 km/ 60 min = 20 km /3 min = 60 km / 9 minComparing the two above, we see y= 9
