x < 0
Step-by-step explanation:
If you were to graph the function, you would get a parabola that opens down with the vertex at (0, 0). So, the graph is increasing from -∞ to 0.
-3x + 18 = 7x
3x + (-3x) + 18= 7x + 3x
18 = 10x
18 10x
— = —
10 10
1.8 = x
48 qrts * 25 barrels per trip = 1200 qrts get picked up per trip
1200 qrts * 1 hr/7qrts = 171.43 hrs to fill all 25 barrels
171.43 hrs * 1 day/24hrs = 7.14 days
