Answer:
-144ft below sea level
Step-by-step explanation:
It is a linear equation. Written as y=14x-270. So what you do is substitute x for 9,
y=14(9)-270
y=126-270
y=-144
I think the answer is A. The submarine was 144 feet below sea level(-144) after 9 minutes.
This is how i got me answer:
z=9
14 x 9 = 126
-270 + 126 = -144
