The absolute value parent function.
The slope of the line (m) = 3/1 = 3
and the y intercept is at (0,3) that is y = 3 so b = 3
using the slope intercept form y = mx + b
m = 3 and b = 3
so answer is y = 3x + 3
Use Pi, 3.14. Divide the Diameter by 3.14 and you should get your answer. That's all I know.
<em>Answer is x + 12</em>

Hello! Recall that you have to write clear questions in order to get exact answers. So I'll help you assuming that the two expressions are the following:
First expression:
![2x+9](https://tex.z-dn.net/?f=2x%2B9)
Second expression:
![x-3](https://tex.z-dn.net/?f=x-3)
So the operation we need to perform is:
![2x+9-(x-3)](https://tex.z-dn.net/?f=2x%2B9-%28x-3%29)
Recall some rules:
![(+)\times (+)=+ \\ \\ (-)\times (-)=+ \\ \\ (-)\times (+)=- \\ \\ (+)\times (-)=-](https://tex.z-dn.net/?f=%28%2B%29%5Ctimes%20%28%2B%29%3D%2B%20%5C%5C%20%5C%5C%20%28-%29%5Ctimes%20%28-%29%3D%2B%20%5C%5C%20%5C%5C%20%28-%29%5Ctimes%20%28%2B%29%3D-%20%5C%5C%20%5C%5C%20%28%2B%29%5Ctimes%20%28-%29%3D-)
Hence:
![2x+9-(x-3)=2x+9-x+3 \\ \\ \\ Combine \ like \ terms: \\ \\ (2x-x)+(9+3) \\ \\ \boxed{x+12}](https://tex.z-dn.net/?f=2x%2B9-%28x-3%29%3D2x%2B9-x%2B3%20%5C%5C%20%5C%5C%20%5C%5C%20Combine%20%5C%20like%20%5C%20terms%3A%20%5C%5C%20%5C%5C%20%282x-x%29%2B%289%2B3%29%20%5C%5C%20%5C%5C%20%5Cboxed%7Bx%2B12%7D)
