Solve the proportion x/12.6=45/63

x=9

Step-by-step explanation:

x/12.6=45/63

We can solve using cross products

x * 63 = 45*12.3

Divide each side by 63

x = 45*12.6/63

x = 9

a

step-by-step explanation:

the answer is a

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.
