Answer: 41, 42, and 43 years old.
Step-by-step explanation:
41 plus 42 plus 43 = 126.
From inspecting the graph, you can identify the y-intercept and the slope of the line shown.
The y-intercept is 200 gallons.
The slope is
75-200
m = ------------- = -12.5 gallons/minute
10 - 0
Thus, y = 200 gallons - [12.5 gallons/minute ]t
To answer the 2nd question, let t = 12 minutes and calculate y(12).
To determine how long it wld take to empty the tank, set the above formula equal to zero and solve the resulting equation for t.
Answer:
it will be C because if u multiplie -6 by 4 it will equle -24 meaning that n=-6
