the expression -300 + 14y represents a submarine that began at a depth of 300 feet below sea level and ascended at a rate of 14 feet per minute what was the depth of the submarine after 9 minutes?​

Respuesta :

Answer:

174 feet below sea level

Step-by-step explanation:

y is the number of minutes so you can multiply 14 by 9

14*9 is 126

then you add 126 to -300

126 + (-300) is essentially 126 - 300 and that is -174

the submarine was at 174 feet below sea level
