8' 4" − 2' 6" = Subtract measurement with Same Difference Theorem

4th option is correct xy=-10

if this was to u plzz mark me the brainliest

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.

just sum

10 + 10 = 20
