x=8
The answer is c I’m pretty sure
Answer:
it y = 2x + b
Step-by-step explanation:
YOU NEED TO PUT THE M FIRST NOT THE X
Answer:

Step-by-step explanation:

break it into pieces



put it all together
*since there's no negative in front of the other numbers except 7 they're positive so you add them*

simplify

Hello.
1. Switch y and x.
x = 10y^2 - 4
2. Isolate y.
x + 4 = 10y^2
(x + 4)/(10) = y^2
y = sqrt[(x + 4)/(10)]
3. Replace y with f^-1(x)
f^-1(x) = sqrt[(x + 4)/(10)]
Good luck to you!
