What is the average rate of change for ƒ(x) = −2x + 70 over the interval 2 ≤ x ≤ 6?

- 2

Step-by-step explanation:

Since the function is linear then the average rate of change is the measure of the slope of the line.

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 2x + 70 ← is in slope- intercept form

with slope m = - 2

Thus rate of change is - 2

answer: 8

step-by-step explanation:

c = 0.429t

step-by-step explanation:

the constant rate at which carlos harvests cassava is 35 minutes per 15 cassavas 15/35 = 0.429 cassava per minute

therefore, an equation that models the number of cassava (c) that harvest carlos in a time (t) is the following:

where t is the time in minutes.

this means that when 35 minutes have elapsed 15 cassava have been harvested, at 70 minutes 30 cassava have been harvested and so on.
