Answer:

The average rate of change is -3

Step-by-step explanation:

we have

f(x)=-3x+1

This is a linear function in slope intercept form  f(x)=mx+b

where

m is the slope

b is the y-intercept

In this problem

The slope is equal to

m=-3

Remember that

In a linear function the average rate of chance is a constant and is equal to the slope of the linear function in any interval

therefore

The average rate of change is -3

Hello could you help me please?
Ilya [14]

Answer:

C. 6

Step-by-step explanation:

So it says read less thann 25 books --> that means the numbers are 13,14,14,16,19,21,21,22,23, and 24 --> a total of 10 numbers

Then it says read more than 35 books --> that means the numbers are 37,41,42,43 --> a total of 4 numbers

Now, it says how many more --> that means you subtract 4 by 10 = 10 - 4 = 6

Therefore the answer is 6 more students read less than 25 books than read more than 35 books.
