s
O
A. x = 0
B. x = 2
c. x= 10
D. X = 20

A. x=0

Step-by-step explanation:

x+20+10x=20+9x

cancel equal terms

x+10x+9x

add x to 10x

11x=9x

move variable to left

11x-9x=0

subtract 11x to 9x

2x=0

divide Both sides by 2

x=0

b) 36

step-by-step explanation:

18 times 2 is 36

part a

x     y

0     8

2     7

3     6.5

4     6

5     5.5  

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

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
