Answer:
It is a function.
Step-by-step explanation:
Functions are relations in which one domain value is assigned to exactly one range value. The x-value must not repeat in the relation set for it to be a function.
{(2,3), (4,3), (6,3), (5,9), (3,9)}
There are no repeating x-values given.
The relation should be a function.

Answer:
80.6
Step-by-step explanation:
F = 9/5 C + 32
F = (9/5)*27 + 32 Substitute 27 into the equation
F = 243 / 5 + 32 Multiply 9 and 27 together
F = 48.6 + 32 Divide by 5
F = 80.6 Add on 32
A very quick way to do this is to double your centigrade temperature and and 30 which you should be able to do in your head.
2*27 = 54 Add 30
54 + 30 = 84
This quick way will tell you if you get near the right answer.
