Answer:
just mark points it is very easy
2x+30y=12x+17
30y=10x+17
y=(10/30)x+(17/30)
x-intercept:
0=(10/30)x+(17/30)
-17/30=(10/30)x
-17/10=x

Answer: 
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.
