Because like terms you add or subtract together to make it easier to do the problem. just like you do with whole numbers. you add an subtract to make the answer simpler.
The rule for reflecting a point over the y-axis is this:
(x, y) ---> (-x, y)
The x term becomes the opposite and the y term stays the same
(3, 4) ---> (-3, 4)
Hope this helped! Let me know if you have any further questions!

First you need to add 10 + 55 and get 65 then do 65xh= that's it
Procedure:
1) Integrate the function, from t =0 to t = 60 minutues to obtain the number of liters pumped out in the entire interval, and
2) Substract the result from the initial content of the tank (1000 liters).
Hands on:
Integral of (6 - 6e^-0.13t) dt ]from t =0 to t = 60 min =
= 6t + 6 e^-0.13t / 0.13 = 6t + 46.1538 e^-0.13t ] from t =0 to t = 60 min =
6*60 + 46.1538 e^(-0.13*60) - 0 - 46.1538 = 360 + 0.01891 - 46.1538 = 313.865 liters
2) 1000 liters - 313.865 liters = 613.135 liters
Answer: 613.135 liters
You will need 3 gallons of paint or 6/2 because 1/2 * 2=1
