The number of water bottles, y, filled in x
minutes by each of two machines is given by the
equations below. use substitution to determine
if there is a point at which the machines will
have filled the same number of bottles.

160x + 2y = 50

y + 80x = 50

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

step-by-step explanation:

the answer would be c:   ax + b = ax + c
