Which pair of numbers is relatively prime? 12 and 81, 12 and 35, 12 and 32, 12 and 27

12 and 35   relatively prime

Step-by-step explanation:

Two integers are relatively prime  if the only number that goes into both numbers is 1

12 and 81  are both divisible by 3 so the are not relatively prime

12/3 =4 and 81 /3 is 27

12 and 35   relatively prime

12 and 32  are both divisible by 4

12/4 = 3 and 32/4 =8

12 and 27 are both divisible by 3

12/3 = 4 27/3 = 9

i will pick c put check it over to be sure

step-by-step explanation:

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
