Answer:
6 < x ≤ 20
Step-by-step explanation:
First, let's use the points (0, 50) and (20, 0) to find the equation of the line.
m = Δy / Δx
m = (0 − 50) / (20 − 0)
m = -2.5
y = -2.5x + 50
Now find the time when y = 35.
35 = -2.5x + 50
-15 = -2.5x
x = 6
So there is less than 35 gallons in the barrel when 6 < x ≤ 20.
Collect like terms
1/2((10x - 8x) - 6y)
Simplify (10x - 8x) - 6y to 2x - 6y
1/2(2x - 6y)
Simplify 2x - 6y/2
2x - 6y/2
Factor out the common term 2
2(x - 3y)/2
Cancel 2
<u>Answer: D. x - 3y</u>
