A tank contains 550 gallons of water. When the valve is opened, the tank drains at a rate of 12 gallons per minute. Which function shows the relationship between the time t the valve is opened and the amount of water in the tank?

Answer 1

y= 550-12x

Explanation:

Given data

Content of tank= 550 gallons

Rate of drain= 12gallon per minute

let the time it will take to drain all 550 gallons be x minutes

Hence the expression for amount of water in the tank after x minutes will be

y= 550-12x
