That is (f(-2)-f(1))/(-2-1)
ust find the slope between the points (-2,f(-2)) and (1,f(1))
f(-2)=(-2)^2+5(-2)-12=4-10-12=-18
f(1)=1^2+5(1)-12=1+5-12=-6
slope between them is (-18-(-6))/(-2-1)=(-18+6)/(-3)=-12/-3=12/3=4
average rate of change is 4
Answer:
Kevin can make 35 pillows.
Step-by-step explanation:
I assume that your question would be, "How many pillows can Kevin make?" If this is not the answer that you were looking for, you need to input your question.
Answer:
8
Step-by-step explanation:
If a = -16 and b = -2, just substitute the values in for the equation.
a/b = -16/-2
The negatives cancel out, since both the numerator <em>and</em> denominator are <em>both</em> negative.
-16/-2 = 16/2
If you symplify, you get 8.
So, your answer is 8
