what is the value of x and y

x= 2

z=117

Step-by-step explanation:

To find x:

63=(6x+51)

Simplify/ Subtraction property

12=6x

Evaluate/ division property

2=x

To find z:

Subtract 180 and 63 to get 117

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.
