Find the inverse function of

m(x) = 5x - 5

1)m-1^(x) = 5x + 5
2)m-1^(x) = -5x + 5
3)m-1^(x) = x+5/5
4)m-1^(x) = x+5/-5 x

y=5x-5

y+5=5x

x=y+5/5

m^-1 (x)=x+5/5

Hope this helps

Step-by-step explanation:

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
