3(n + 25) = 50 + 2n

Step-by-step explanation:

5 x 3/5 = 15/5.  Simplify...

3

5(10 + 2/5 n )

50 + 10/5 n

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.
