Tyler needed to get his computer fixed. He took it to the repair store. The technician at the store worked on the computer for 5 hours and charged him $112 for parts. The total was $237. What was the cost of labor, per hour?

$25 dollars per hour

Step-by-step explanation:

I subtracted the parts (Doesn't count), and I took the remaining balance and divided it by 5 hours to get the amount per hour.

for ex: the reciprocal of 3/4 is 4/3. it is the opposite.

reciprocal definition:

a mathematical expression or function so related to another that their product is one; the quantity obtained by dividing the number one by a given quantity.

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )
