Jesse is not allowed to work more than 20 hours each week at his part time job . he has already worked 4 hours this week. the inequality shown can be used to find h, the number of hours jesse can still work this week.

Been a bit since i’ve done this kind of problem.

X+4=20

X is the number of hours needed to work, while 4 is the hours already there.

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

0       8

1       7.6

2       7.2
