(12x^2 + 3x + 6) + (-7x^2 – 4x – 2) = 5x^2 - x + 4
(2x2 – x) + (-x – 2x2 – 2) = -2x - 2
(x3 + x2 + 2) + (x2 – 2 – x3) = 2x^2
(x2 + x) + (x2 + 8x – 2) = 2x^2 + 9x - 2

Answer:
The owner will have to pay $ 125 after 2 hours.
Step-by-step explanation:
Given that the line graph shows the amount of water loss in a leaking tank during 7 hours, and the owner pays $ 1 for every 8 liters of water lost, to determine how much will he have to pay after 2 hours the following calculation must be performed :
((6000 - 5000) / 8) x 1 = X
(1000/8) x 1 = X
125 x 1 = X
125 = X
Therefore, the owner will have to pay $ 125 after 2 hours.
