A 30 gallon tub is completely full. The drain is opened and the tub begins draining at a of 1.5 gallons per minute. How long will it take the tub to completely drain?

1.5÷60=0.025 per second

30÷0.025=1200 second

1200÷60 =20 hours

20 hours

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
