What is the value of y? 18+2y+4+10+2x+10

1) 18+2y+4+10+2x+10

2) 42+2y+2x

3) 42+2x=-2y

4) -1(42-2x=2y)

5) (42-2x=2y)/2

y=21-x

Step-by-step explanation:

1) Original equation

2) Combine like terms

3) Since the problem is asking to find the value of Y, Isolate it

4) Multiply by a negative to make Y positive

5) Since what we have left isn't in simplest form, divide by 2

What is left is y=21-x or y=-x+21

The relation represents y as a function of x, because each value of x is associated with a single value of y. (B)

Step-by-step explanation:

The relation definitely represents y as a function of x, so we can already eliminate two of the answers that say it does not represent. (It does not repeat)

There is one x value paired with one value of y. There isn't two values of x paired with one value of y.

Therefore, our answer is B, The relation REPRESENTS y as a function of x, because each value of x is associated with a SINGLE value of y.
