What is the result of subtracting the second equation from the first?
–3x +2y=7
-3x – 2y = 4

4y = 3

Step-by-step explanation:

To subtract the 2nd equation from the first, negate all three of the second equation terms:  3x + 2y = -4

and then add (combine) this result to (with) the first equation:

 -3x + 2y = 7

  3x  +2y = -4

           4y = 3  (this is the desired result))

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
