Which expressions are equivalent to 2(25)?
2(20 + 15)
2(10 + 15)
2(2 + 5)
2(20 + 5)

answer: no, but if it does it's a obvious pattern.

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.

answer: x=3 and y=4
