A water tank is draining. The volume of the water in the tank, in gallons, is a linear function of the amount of time it has been draining, in hours. It can be modeled using the equation V (t) = –12.8t + 685, where V is the volume and t is the time. Explain what the values -12.8 and 685 mean in the context of this problem.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

idk what the heck he answer is, i’m just putting this here so i finish my account

i those same problems in math and dont know how to do them
