Solve for x. -3x + 4 = -8
a) x = 4
b) x = -4
c) no solution
d) x = - 4 /3

Your answer is definitely going to be:

A) x = 4

Step-by-step explanation:

I literally just took this test the other day.

you probably already have the answer but anyways it's b. 15.0

step-by-step explanation:

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.
