Question

There is 1 in. of water in a pool. The water level is increasing at 0.75 in./min . Which linear equation represents the total depth of the water, in inches, after x minutes?

A. 1+y=0.75x

B. y=0.75x+1

C. y=0.75x

D. x=0.75y

Answer 1

y = 0.75 + 1 → B

increasing at 0.75 in/min , thus 0.75x after x min

The depth is already at 1 in

y = 0.75x + 1 is the equation.
