(-5k^3 – 6k + 1) +(-6k^2 + 5k)

I assume you have to simplify the expressions.

-5k^3-6k^2-k+1 is the answer.

Step-by-step explanation:

-5k^3-6k^2-k+1

Step-by-step explanation:

rewrite without parentheses

-5k^3-6k+1-6k^2+5k

group like terms

-5k^3+1-6k^2+(-6k+5k)

-5k^3-6k^2-k+1

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
