If C is the midpoint of AB and AB = 20, what is AC?

AC = 10

Step-by-step explanation:

AC+ BC =AB

If C is the midpoint then AC = BC

AC + AC = 20

2 AC = 20

Divide by 2

2AC /2 = 20/2

AC = 10

correct answer:

i^31 = -i

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
