What is the solution to the equation 2x+4-12=20 x=0 x=1 x=2 x=9

x=2

Step-by-step explanation:

Given a linear equation with x as a variable

The equation is

Now add 12 to both the sides

Divide by 2

Take 4th root both the sides

we get

x =2

So answer is x=2

Verify:

Substitute 2 for x in the equation given and check

Left side =

Verified

21

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.
