Answer:
y= -4x+4
Step-by-step explanation:
y=mx+b
where x=-1, y=8, and m=-4
8=(-4)(-1)+b
8=4+b
4=b
Thus, y= -4x+4

Answer: -4
Step-by-step explanation:
2.5x = -10
1. divide -10 by 2.5
2. x = -4
In order to reach the total cost of $128, you need to find the number of hours the company cleaned. The equation to do so would be
30x+ 8 = 128
If you subtract 8 from both sides and then divide by 30 you'll find that x=4.
