Answer:

Step-by-step explanation:

You haven't given the equation, but I can make one up.

Cost = 55 + 42*h

So let the cost = 265 dollars

265 = 55 + 42h Subtract 55 from both sides

210 = 42h Divide both sides by 42

210/42 = 42h/42

h = 5

What is the rate of change seen in the graph below?

eimsori [14]

Answer:

- 2

Step-by-step explanation:

Rate of change is the measure of the slope m

Calculate the slope using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (0, 2 ) and (x₂, y₂ ) = (1, 0) ← 2 points on the line

m = $\frac{0-2}{1-0}$ = $\frac{-2}{1}$ = - 2
