let's recall that to find the inverse of any expression, we start off by doing a quick switcheroo on the variables, and then solve for "y".

Answer:
c=-9x^2-15x
Step-by-step explanation:
Answer:
b = 12.6
Step-by-step explanation:
a*2 + b*2 = c*2
6*2 + b*2 = 14*2
36 + b*2 = 196
Subtract 36 from both sides
36 + b*2 = 196
-36 -36
b*2 = 160
Find the square root of both
b = 12.64911064 or 12.6
