Please answer the math question in the picture as I’m not able to do it,, thank you very much in advance :))

11

step-by-step explanation:

32.50-7.50=25

225/25=11

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

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.
