-x^2 + 4x + 12 = -3x + 24

-> x^2 - 7x + 12 = 0

-> (x-3)(x-4) = 0

-> x= 3 or 4

so y = 15 when x = 3, y = 12 when x = 4

Blake's pool can hold 2.539 gal of water when full. If it takes 9 hours to fill the empty pool. How much water will be in the po
Dovator [93]

Answer:

0.2821 gal

Step-by-step explanation:

Since this is a direct and proportional relationship, we know that the ratio for 2.539 gal of water to 9 hours is the same as the ratio from the water in the pool after 1 hour to 1 hour. Therefore, we can simplify 2.539:9 into 0.2821111... I’m not sure what value you must round to, so I’ll assume it is to the nearest thousandth. Hence, our answer is 0.2821 gal.

I hope this helps! :)
