Afamily of four goes to a salon for haircuts. the cost of each haircut is $13. use the distributive property and mental math to find the product 4 × 13 for the total cost.

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

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.
