Answer:

<em>r = 3.5 acre/hour</em>

Step-by-step explanation:

<u>Rate of Change</u>

Farmer Fran had harvested 2 acres of pomegranates at 10:00 A.M. At noon (12:00 P.M.) she had harvested 9 acres.

From both times, 2 hours had passed. During that time, she harvested 9-2=7 acres.

The rate of harvesting is:

r=\frac{7}{2}\ acre/hour

Or, expressed in decimal:

r = 3.5 acre/hour

It goes by 8!

If u see, 4 + 8= 12 +(another) 8 = 20! It skips 8 every time!

If u were to continue it, 20 + 8 = 28 and so on!
The difference is the sum of the number totalled.

Answer:

<h2>h(-8) = -8</h2>

Step-by-step explanation:

Put x = -8 to the formula of <em>h(x)</em>

h(x)=\dfrac{x^2+3x}{4x+27}\\\\h(-8)=\dfrac{(-8)^2+3(-8)}{4(-8)+27}=\dfrac{64-24}{-32+27}=\dfrac{40}{-5}=-8
