For the situation described first write the equation in the form y=mx+b. Then solve: A water tank holds 18,000 gallons. How long will it take for the water level to reach 6000 gallons if the water is used at an average rate of 450 gallons per day?

It will take 13.33 days to fill it to 6,000 gallons.

Step-by-step explanation:

13.3 Days | 6,000 = 450 (13.3) + 0

Step-by-step explanation:

6,000 = 450 (x) + 0

m = Rate of 450 gallons

x = Quanity of days passed

b = starting amount in tank

y = total amount of gallons in the tank

6,000/450 = 13.3 repeating

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
