Answer:
$289
Step-by-step explanation:
If you know the cost of one of the two items, you can subtract that item from the total in order to find the price of the second item
So: total price - computer price = printer cost
So: $1039- $750 = $289
The printer is $289
Answer:
4
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is

Here [ a, b ] = [ 3, 4 ] , then
f(b) = f(4) = - 1 ← from table
f(a) = f(3) = - 5 ← from table , then
average rate of change =
=
= 4
78, because you have to do the inverse operation so 80/2= 40 then 40-1= 39 and 39*3 = 78
