Hideki is draining a 45-gallon aquarium at a rate of 15 gallons per minute. what is the initial value of the linear function that represents this situation?

45-gallons

Step-by-step explanation:

Hideki is draining a 45-gallon aquarium at a rate of 15 gallons per minute.

Draining the gallons. So, rate should be negative because it reduce the amount of number of gallons.

Rate = 15 gallons per minute

Initial value = 45 gallons

Let t number of minutes aquarium left gallons.

This is linear function of given situation.

where, initial value is 45 and rate is 15

Hence, The initial value of the given situation is 45-gallons
