Ignore the bottom but can someone help me and give me the right answer please also put how you got the answer so show your work please

4x-15

Step-by-step explanation:

5(x-3)-x

first we want to distribute 5 to x and -3

5xx=5x 5x-3=-15

now we have

5x-15 - x

then we just have to combine like terms and the only alike terms are 5x and -x

5x-x=4x

so the answer is 4x-15

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.
