(2x + 29) + 91 = 180.
This is because they add to form a straight line which is 180 degrees, in other words the angles are supplementary.
2x + 29 = 89 (Subtract 91 from each side)
2x = 60 (Subtract 29 from each side)
x = 30 (Divide 2 from each side)
x = 30
The answer is B
(x-7)(4x^2-x+3)
4x^3-x^2+3x-28x^2+7x-21
4x^3-29x^2+10x-21
Answer:
Domain of inverse:
Range of inverse:
Explanation:
The domain and range swap. This is because the inputs (x) and outputs (y) swap roles when going from the original function to the inverse, and vice versa.
I think you left some information out but rewrite it in the comments and I will answer it I already did this
