describe how you can tell by lookin at a graph of a function which variable is the input variable and which is the output variable
Answer:
The output variable will be on the y-axis, the input variable will be on the x-axis.
Step-by-step explanation:
To create a function, we must an equation in the form of
[tex]Y(x) = kx + b[/tex]
The x-axis of a graph will be what we change in the function. We will get a certain value ([tex]Y(x)[/tex]) that changes when the right side of the function changes. This means that the input of the function will be [tex]x[/tex].
The y-axis of a graph will be what the x-axis makes. In this case, it's [tex]Y(x)[/tex]. This is the output of the graph after given the input. This means the output is [tex]Y(x)[/tex].

Answer:
A 22w = 1540
B Width = 70 feet
Length = 700 feet.
Step-by-step explanation:
A. If the width is w then the length is 10w.
Perimeter = 2* (length + width) so
2(10w + w) = 1540
22w = 1540.
B. 22w = 1540
w = 1540 / 22
w = 70 feet.
l = 70 * 10 = 700. feet.
sarah is drawing a parallelogram abcd on a coordinate plane. the parallelogram has the coordinates A(-7,5) B(6,5) and D(-9,-2). which of the following coordinates should sarah use for point c?
A. (6,-3)
B. (4,-5)
C. (4,-2)
D. (6,3)
Answer:
(4,-2)
Step-by-step explanation:
Okay, I figured out the answer...
You need to use the [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{2}}[/tex] formula.
We know that AB is parallel to CD....(so whatever answer ad is, then cd will have that same answer).
We also know that AD is parallel to BC...(so whatever answer ad is, then bc will be the same).
So we need to find AB, CD, AD, BC. We have to do CD and BC later because we don't have the c.
Find AB: [tex]\frac{5-5}{6-(-7)}[/tex]= [tex]\frac{0}{13}[/tex]= 0
Find AD: [tex]\frac{-2-5}{-9-(-7)}[/tex] = [tex]\frac{-7}{-2}[/tex]
So now that we have the basic ones, we know that AB is parallel to CD. Therefore CD should have the same slope of 0/13 or 0. SO we need to find numbers that combine with the x and y of AB. When they do combine, they should give a fraction of 0/13.
Find CD: [tex]\frac{-2+2}{-9-4}[/tex] ( we already had the -2...what number adds to -2 to make it zero?...positive 2.....Then, we already had -9 from the D coordinates. So what # adds/subs to -9 to make it 13 or -13...well 4 does. Remember to put the correct signs (-+) in the equation. Our answer is 4,-2). If we had to use positive two, then we take the opposite for our answer. We used -4, so we take the opposite for our answer. Then later on, you can plug in (4,-2) into BC to see if you were to get the slope of -7/-2. which you do.

Sally takes 2 5/6 minutes to drive from her home to the local shopping center. She spends 1/5 of this time waiting at traffic lights. Find the number of minutes she spends waiting.
Answer:
[tex]\dfrac{17}{30}[/tex] minutes.
Step-by-step explanation:
It is given that Sally takes [tex]2\dfrac{5}{6}[/tex] minutes to drive from her home to the local shopping center.
[tex]2\dfrac{5}{6}=\dfrac{2(6)+5}{6}[/tex]
[tex]2\dfrac{5}{6}=\dfrac{12+5}{6}[/tex]
[tex]2\dfrac{5}{6}=\dfrac{17}{6}[/tex]
She spends 1/5 of this time waiting at traffic lights.
Waiting time in traffic [tex]=\dfrac{17}{6}\times \dfrac{1}{5}[/tex]
[tex]=\dfrac{17}{30}[/tex]
Therefore, waiting time is [tex]\dfrac{17}{30}[/tex] minutes.

What is the equation of a line that is perpendicular to y = -1/5x + 1 and passes through point (0, -2)?
Answer:
y = 5x - 2
Step-by-step explanation:
The slope will be 5, because that is the opposite reciprocal of the original slope, -1/5
Then, plug the slope and the given point into y = mx + b to find b:
y = mx + b
-2 = 5(0) + b
-2 = 0 + b
-2 = b
Then, plug the y-intercept and the slope into the equation:
y = 5x - 2 will be the equation

Find the sum of 2x^2 - 6x - 2 and x^2 + 4x
Answer:
3x^2-2x-2
Step-by-step explanation:
2x^2 - 6x - 2 and x^2 + 4x
2x^2 - 6x - 2 +x^2 + 4x
Combine like terms
2x^2 +x^2- 6x + 4x- 2
3x^2 -2x -2
Based on the calculations, the sum of 2x² - 6x - 2 and x² + 4x is equal to 3x² - 2x - 2.
How to solve a quadratic equation?In Mathematics, the standard form of a quadratic equation is given by this mathematical expression:
ax² + bx + c = 0.
In this exercise, you're required to determine the sum of the given quadratic equations. Thus, we would add the equations together as follows:
2x² - 6x - 2 + x² + 4x
Combining like terms, we have:
2x² + x² + 4x - 6x - 2
3x² - 2x - 2

Benito embroiders and sells T-shirts. The graph shows his profit as a function of the number of shirts sold. After selling a certain number of shirts, Benito uses some earnings to buy more materials and then increases the price of the shirts. Which of the following correctly compares the two parts of the function in Part A, over the intervals [0, 7] and [8, 11]? . . Benito made an extra $25 after selling 7 shirts. The price of one shirt increases from $10 to $15. Benito spent $1 after selling 50 shirts Benito's profit per shirt increases from $10 to $15.
Answer:
The correct option is;
Benito's profit per shirt increased from $10 to $15
Step-by-step explanation:
Over the interval [0, 7] from 0 to 7 on the x axis, we have;
At x = 0, y = -20, therefore the y-intercept = -20
At y = 0, x = 2 which is the x-intercept
The slope, m₁ of the straight line plotted dots on the interval from 0 to 7 on the x axis is found as follows;
m = (y₂ - y₁)/(x₂ - x₁)
m₁ = (0 - (-20))/(2 - 0) = 10
The equation of the interval is therefore;
y - 0 = 10×(x - 2)
y = 10·x - 20
Therefore, the profit, y increases by $10, for each shirt, x, sold over the interval from 0 to 7 on the x axis
Over the interval [8, 11] from 8 to 11 on the x axis, we have;
At x = 9, y = 40,
At x = 11, y = 70
The slope, m₂ of the straight line plotted dots on the interval from 8 to 11 on the x axis is found as follows;
m = (y₂ - y₁)/(x₂ - x₁)
m₂ = (70 - 40)/(11 - 2) = 15
The equation of the interval is therefore;
y - 70 = 15×(x - 11)
y = 15·x - 165
Therefore, the profit, y increases by $15, for each shirt, x, sold over the interval from 8 to 11 on the x axis.

Step-by-step explanation:
Choose the number in which the digit 2 is ten times greater than the digit 2 in 426.
Answer: 237
Step-by-step explanation:
Ok we can write 426 as:
400 + 20 + 6
Then the 2 in 426 is in the place of the tens and represents a 20.
If we want a number with a 2 that is 10 times greater than 20, we have that:
10*20 = 200.
Then we should find a number with a 2 in the hundreds place, an example can be:
237
where we can write this number as:
237 = 200 + 30 + 7
and the 2 is in the hundreds place.

An item has a listed price of $80. If the sales tax rate is 7%, how much is the sales tax (in dollars)
Multiplying a listed price by the percent can get you the sales tax, and then you can add.
[tex]80*0.07=5.6[/tex]
(0.07 is 7% converted into a decimal)
[tex]80+5.6=85.60[/tex]
So the item is $85.60 after sales tax.
You may also notice that multiplying the listed price by 1.07 will get you the same answer, without the need to add the sales tax.
[tex]80*1.07=85.60[/tex]

Find the value of (x) 2x + 2(-3x-5)=26
Answer:
x = -9
Step-by-step explanation:
Solve for x:
2 (-3 x - 5) + 2 x = 26
2 (-3 x - 5) = -6 x - 10:
2 x + -6 x - 10 = 26
2 x - 6 x = -4 x:
-4 x - 10 = 26
Add 10 to both sides:
(10 - 10) - 4 x = 10 + 26
10 - 10 = 0:
-4 x = 26 + 10
26 + 10 = 36:
-4 x = 36
Divide both sides of -4 x = 36 by -4:
(-4 x)/(-4) = 36/(-4)
(-4)/(-4) = 1:
x = 36/(-4)
The gcd of 36 and -4 is 4, so 36/(-4) = (4×9)/(4 (-1)) = 4/4×9/(-1) = 9/(-1):
x = 9/(-1)
Multiply numerator and denominator of 9/(-1) by -1:
Answer: x = -9

The two lines shown intersect at the point (a,b). Find ab. Each unit square in the grid represents a distance of 1.
Answer:
(9/5, 8/5)
Step-by-step explanation:
First you want to find the equations of the lines. One line is y = 2x - 2 and the other line is y = 1/3x + 1. Then you want to find the x and y that both work in the two equations.
y = 2x - 2
y = 1/3x + 1
Then you do 2x - 2 = 1/3x + 1
Then you do some maths and you get 9/5, and 8/5
