First one is a function and the second one is also a function !
Answer:
12
Step-by-step explanation:
4y = 48x
Divide each side by 4
4y/4 = 48/4
y = 12x
The constant is 12
Answer:
![\textsf {C. -2}](https://tex.z-dn.net/?f=%5Ctextsf%20%7BC.%20-2%7D)
Step-by-step explanation:
![\textsf{In the equation y = mx + b, m is the slope and} \\\textsf{b is the value of the y-intercept.}](https://tex.z-dn.net/?f=%5Ctextsf%7BIn%20the%20equation%20y%20%3D%20mx%20%2B%20b%2C%20m%20is%20the%20slope%20and%7D%20%5C%5C%5Ctextsf%7Bb%20is%20the%20value%20of%20the%20y-intercept.%7D)
![\textsf {The line has a y-intercept at (0, -2), hence b = -2.}](https://tex.z-dn.net/?f=%5Ctextsf%20%7BThe%20line%20has%20a%20y-intercept%20at%20%280%2C%20-2%29%2C%20hence%20b%20%3D%20-2.%7D)
The change in the first round is -22.
The change in the second round is unknown, so we let x = the change in the second round.
When we add the two changes we get an overall change of 0.
-22 + x = 0
Add 22 to both sides of the equation.
x = 22
The change in the second round is 22 points because when you add 22 points to -22 points you get the overall change of 0 points.
