Answer: {(1, 8.65), (2, 8.30), (3, 7.95)}
EXPLANATION
Given,
The watering can dispenses water at a rate of 0.35 gallon
per minute.
The original volume of water in the can was 9 gallons.
Therefore if,
y = the volume of water in the can in gallons
x = time in minutes
f(x) = y = 9 – 0.35x
When x = 1,
y = 9 – 0.35(1)
y = 9 – 0.35
y = 8.65
Therefore we have the pair (1, 8.65)
When x = 2,
y = 9 – 0.35(2)
y = 9 – 0.7
y = 8.3
Therefore we have the pair (2, 8.30)
When x = 3,
y = 9 – 0.35(3)
y = 9 – 1.05
y = 7.95
Therefore we have the pair (3, 7.95)
The 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 is {(1, 8.65), (2, 8.30), (3, 7.95)}
