Answer: 5) Needs more info 6) 4 hours 7) y<-6

Step-by-step explanation:

5) Needs more info, what was the initial question?

6) So the employee rate for washing cars turns out to be 4*5 = 20 hours to wash 20 vehicles

Therefore, 5 employees will wash 5 vehicles in 1 hour

5 employees will wash 20 vehicles in 1*4 = 4 hours

7) y+4<-2

= y+4-4<-2-4

= y<-6

To graph the inequality, just draw a horizontal line through (0,-6)
