Carrie and krystal are taking a road trip from greenville to north valley. each person has her own map, and the scales on the maps are different.
a. on carries map, greenville and north valley are 4.5 inches apart. the scale on her map is 1 inch=20 miles
b. the scale on krystal's map is 1 inch=18 miles. how far apart are greenville and north valley on krystal's map.

if x decreases by 4 then y increases by 10

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.
