Solve the equation 7[X-4] - 2[X-3(5+X)] = 2/3[X-6]

Hello! :) have a good day!

Exact Form:

x = −18/31

Decimal Form:

x = −0.58064516

x = -2

y = 848

step-by-step explanation:

plug in the numbers

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.
