1. X3, 15x - 10y = 80 15x - 7y = 51
-17y = 29
2. 8 = 1/60 + a. 8 - 1/60 = 7.98333333333
6 = 1/80 + b. 6 - 1/80 = 5.9875
13.9708333333

since the slopes are equal the lines are paralell
Answer:
20 cubic inches
Step-by-step explanation:
Answer:
see below
Step-by-step explanation:
First line:
y = mx+b where m is the slope and b is the y intercept
y = 2x + 10
Second line
y = mx+b
y = 3x+0 since there are no barrels filled on this line when they flip the switch
Setting the two equations equal
2x+10 = 3x
Subtract 2x from each side
2x+10-2x= 3x-2x
10 = x
Each line will have filled 10 barrels when they numbers are equal.
