Why are the solutions to the proportions 50/x=10/20 and 10/50=20/x the same?

a. because both result in the equation 20x=500, which simplifies to x = 25

b. because both result in the equation 20x=500, which simplifies to X= 250

c. because both result in the equation 10x= 1,000, which simplifies to x= 10

d. because both result in the equation 10x= 1,000, which simplifies to X=100

c: lkllmn.

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.
