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

The answer is c the third one
Answer:
it means your adding it again lets use your example.
Step-by-step explanation:
Your increasing by 100% because 100% of 5 is 5 so your just addding 5+5 which is 10.

Answer:
Sample mean = 30
Standard deviation = 10
Step-by-step explanation:
A system with two linear equations can be modeled with the information given in order to find the sample mean (M) and the standard deviation (s):
Solving the linear system:
The sample mean is 30 while the standard deviation is 10.
