B. Olivia and Isabella want to find out how much money they earn altogether. Suppose they earn $12 for each dog walk. Will you get a different amount if
you evaluate Isabella's expression instead of Olivia's? Explain.

$18

Step-by-step explanation:

you have to subtract 12 from the ration of dogs that they will walk

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.

if you was gonna solve for a, a is a   < -12
