Step-by-step explanation:
Average rate of change is just the slope between the 2 points
we can do this the long way or the smart way
long way, find the 2 points and find the slope between them
when x=-5, f(-5)=-2(-5)+1=10+1=11
when x=1, f(1)=-2(1)+1=-2+1=-1
so the points are (-5,11) and (1,-1)
the slope between them is (-1-11)/(1-(-5))=(-12)/(1+5)=-12/6=-2
the answer is B, -2
smart way
recognize that that is a linear equation and the slope between any 2 points will be the m in y=mx+b
f(x)=-2x+1
the slope is -2
the average rate of change is -2
answer is B. -2
Answer:
$15
Step-by-step explanation:
Each cup is 50 cents which is basically $0.50
Multiply $0.50 by 120= $60

divide 60 by 4 to get your own profit:
60/4=15
Answer: 20+7b
Step-by-step explanation:
Given
(6+7b)+14
Take off parentheses
=6+7b+14
Move like terms together (Commutative property)
=6+14+7b
Combine like terms
=20+7b
