∠A and \angle B∠B are supplementary angles. If m\angle A=(2x+10)^{\circ}∠A=(2x+10)
∘
and m\angle B=(2x+2)^{\circ}∠B=(2x+2)
∘
, then find the measure of \angle A∠A.

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

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.
