9. water is added to two containers for 20 minutes. the equations below model the ounces of
water, y, in each container after x minutes. at the time when the containers hold the same
amount of water, how much water do they hold?
container a: y=62x+48
container b: y=-2x2 +80x+120
234 ounces
482 ounces
792 ounces
920 ounces

792 ounces

Step-by-step explanation:

At the time when the containers hold the same amount of water the value of y in the equations is the same,  so

Solve the quadratic equation:

Take only the positive solution since x is positive (minutes)

Now, compute the amount of water y by replacing x = 12 in any of the two equations, for example in container A which is easier to calculate

y = 62(12) + 48 = 792

The correct answer is then 792 ounces
