2. aaliyah's water bottle has 600 lof water, and is leaking at a rate of 5 liters per
minute. bella's water bottle has 400 l of water, and is leaking at 3 liters per minute.
how many minutes, m, will it take for the two water bottles to have the same amount of
water?

100 minutes

Step-by-step explanation:

600 - 500 = 100  

400 - 300 = 100

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
