Question

A watering can dispenses water at a rate of 0.15 gallon per minute. The original volume of water in the can was 5 gallons. Which set of ordered pairs shows the volume of water in the can in gallons (y) as a function of time in minutes (x) from the first minute after the can starts dispensing water? {(1, 5.0), (2, 4.85), (3, 4.60)} {(5.0, 1), (4.85, 2), (4.70, 3)} {(1, 4.85), (2, 4.70), (3, 4.55)} {(4.85, 1), (4.70, 2), (4.45, 3)}

Answer 1

Y equals volume of water, x equals time. If they ask to find the coordinates at one minute, then the first thing you should do is set x equal to 1. That leaves two possible answers. Finally you need to decide how much water is lost in one minute. if you need more help leave a comment.
