Answer:
4,260 feet below sea level (-4,260 feet)
Step-by-step explanation:
The submarine starts at sea level which should be 0 for elevation. And descending 7 feet per second for 2 minutes which means it went down 840 feet ( 7x60x2). Then 4 feet per second for 3 minutes which is 720 feet (4x60x3). Lastly 9 feet per second for 5 minutes which is 2,700 feet (9x60x5). Then you add up those three totals, 840 + 720 + 2,700 = 4,260. So the elevation is -4,260 feet, or 4,260 feet below sea level
She should multiply y = x - 2 by -4...that way one x will be -4x and the other will be 4x and they will cancel out when added.
answer is -4
