Question

Help me answer this please

Answer 1

Answer:

77 feet below sea level.

Step-by-step explanation:

Since y is the time the submarine is ascending, we can plug it in for y and find our answer. We can create an equation where D is the depth and y is time ascending: D = -230 + 17y

Substitute 9 for y:

D = -230 + 17(9)

D = -230 + 153

D = -77

The depth of the submarine after 9 minutes will be 77 feet below sea level. Hope this helps, and Brainly will be highly appreciated.
