×-y=0
×+y=-2
what is the solution to the system of equations

Use the first equation to get x in terms of y by moving y to the right side leaving you with x=y. Plug in y for x in the second equation and get y+y=-2 then 2y=-2. Divide by 2 and y=-1. Plug -1 in for y and you get x-(-1)=0 which solves to x=-1. Both variables equal -1.

d is the correct answer

step-by-step explanation:

x= 8 because 3x = 3 * 8, and 3*8 = 24

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
