Solve for z:
15 = -45 + z
Z=?

15 = -45 + z

Bring 45 to the other side by adding it to both sides.

15 + 45 = 60

60 = z

z = 60

Therefore, the value of z is 60.

z = 60

Explanation: To solve the equation 15 = -45 + z, notice that the variable is on the right side of the equation. Don't let this throw you off.

To solve for z, we need to get z by itself on

the right side of the equation by adding 45.

However, if we add 45 to the right side of the equation,

we also must add 45 to the left side of the equation.

On the right, the -45 and 35 cancel each other out and we have z and on the left side of the equation, 15 + 45 is 60.

So we have z = 60 which is

the solution to our equation.

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.
