Sorry but I don’t know the answer to this question
Answer is false, because every function is a relation but every relation is not a function :) (Please mark me brainliest)
Answer:
To add or subtract some rational numbers, you have to change the rational numbers so they have a common denominator. When you have a common denominator, you can then go on with the addition or subtraction on the numerator part.
Basically just add them all together like normal addition except there is a z attached to each number:
43z + 15z + 7z + 5z + 46z + 14z
58z+ 7z + 5z + 46z + 14z
65z + 5z + 46z + 14z
70z + 46z + 14z
116z + 14z
130z
Hope this helped!
