Hey, I assume that y2 is "y squared"? Have you tried replacing x with 3 and y with 2 in the equation and seeing what you get?

i dont understand what your trying to say

luffingsails · Answer

Well, think about this... if you have the equation x+y and I said x =2 and y = 3. What is the value of x+y?

You'd say x + y = 2 + 3 = 5. Same applies with your problem.

He means that his problem is this
$$5x+\frac{1}{2}*y^2$$

luffingsails · Answer

Yep, just plug and chug... 

5(3) + 1/2 * (2)^2 = 15 + 1/2 * 4 = 15 + 2 = 17.
