A yard cleanup service charges a $380 fee plus $14 per hour.
380 + 14x
Another cleanup service charges a $260 fee plus $20 per hour.
260 + 20x
How long is a job for which the two companies' costs are the same?
380 + 14x = 260 + 20x
380 - 260 = 20x - 14x
120 = 6x
20 = x

Answer:
a
Step-by-step explanation:
x+2y=-10
-x -x
2y=-10-x
y=(1/2)x-5
This is one of the lines and reduces the options to a or c.
3x-y=12
-3x -3x
-y=12-3x
y=3x-12
This is the line with the positive slope and since both lines match, the answer is a.
