Can you solve 2x + 17 = 29 by first dividing and then subtracting? Do you get the same answer if you subtract first and then divide?

You cannot divide first because in equations you need to isolate the variable, which means subtracting first. The outcome will be different if you change the order.

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

3       6.8
