I’m not sure on the answer choices but this is what I got when I did synthetic division.
The cylinder is a clue to use cylindrical coordinates. Taking

and

, we then are forced to use

. So the parameterization of the intersection of the plane and cylinder is

To get the surface, we can introduce a second parameter

that "contracts" the elliptical intersection to a point. The simplest way to do this is to use

with

and

.
Answer:
Step-by-step explanation:
The slope and the y intercept (you can tell there linear if the slope is the same and the y-intercepts are different).
It is already simplified because there is nothing you can divide into both 18 and 25 that would result in whole numbers.
Answer:
10
Step-by-step explanation:
f(-3)=-2(-3)+4=6+4=10
