Question

7.77 - 1.66x + 16.7x

Answer 1

15.04

Explanation:

7.77−1.66x+16.7x

Combine −1.66x and 16.7x to get 15.04x.

d/dx (7.77+15.04x)

The derivative of a polynomial is the sum of the derivatives of its terms. The derivative of a constant term is 0. The derivative of ax^n is nax^n-1.

15.04x^1-1

Subtract 1 from 1.

15.04x ^0

For any term t except 0, t ^0 =1.

15.04×1

For any term t, t×1=t and 1t=t.

and that leaves us with 15.04 as your answer
