100 * pi = pi * r^2
Pi cancels on both sides of the equation
So... 100= r^2
= radius is 10
Answer:
-50
Step-by-step explanation:
b-5 
b-5 = -45 ( collect like terms)
b = -45 + -5
b = -45 -5 b = -50
The slope would be positive in this case
You’re answer would be x=7
Answer:
the answer is C. No, it fails the vertical line test.
