Evaluate 9x - 4y if x=3 and y= -2

35

Step-by-step explanation:

9x-4y

9(3)-4(-2)

27-4(-2)

35

y = mx+b

10 = 9/8(0) + b

b = 10

Equation: y = 9/8x + 10

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.
