what’s the answer to the problem above?

100

70

30

(i thought it was 130 but i got that wrong the first time so i left it out of the options)

Notice the lines and angles are in parallel.

(x + 10)   and 40  are corresponding angles.

And corresponding angles are always equal

Therefore:

x + 10 = 40

x = 30 degrees

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.
