Answer:

−15w+25z

Step-by-step explanation:

Let's simplify step-by-step.

−5w−5(−4z+2w)+5z

Distribute:

=−5w+(−5)(−4z)+(−5)(2w)+5z

=−5w+20z+−10w+5z

Combine Like Terms:

=−5w+20z+−10w+5z

=(−5w+−10w)+(20z+5z)

=−15w+25z

Aliun [14]

Answer:

The average rate of change = -10

The crop yield decreased by 10 pounds per acre from year 10 to year 20.

Step-by-step explanation:

A farmer is tracking the number of soybeans his land is yielding each year. He finds that the function f(x) =-x^2 + 20x + 100 models the crops in pounds per acre over x years.

The average rate of change can be calculated using formula

\dfrac{f(b)-f(a)}{b-a}

In your case,

a=10\\ \\b=20,

then

f(a)=-10^2+20\cdot 10+100=-100+200+100=200\\ \\f(b)=-20^2+20\cdot 20+100=-400+400+100=100

and the average rate of change is

\dfrac{100-200}{20-10}=\dfrac{-100}{10}=-10

This means the crop yield decreased by 10 pounds per acre (negative rate of change) from year 10 to year 20.
