Combine like terms 3/4a +1/2b - 1/2a a) 1/4a + 1/2b b) 1/2b - 3/8a c) 3/4a d)3/4ab

A) 1/4a + 1/2b

Step-by-step explanation:

3/4a +1/2b - 1/2a

3/4a -1/2 a     + 1/2 b

We need a common denominator for the a terms which is 4

3/4a - 1/2*2/2 a  + 1/2 b

3/4a -2/4a     + 1/2 b

1/4a + 1/2 b

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
