im not shure.help

Answer 1

i think b

Answer 2

If adding y and subtracting y lead to the same result, then y must be 0. So then x has to be...?

Answer 3

I THINK B

Answer 4

If x and y are both 0 then x + y = 0

Answer 5

am i correct?????????

Answer 6

I believe it is Zero. Because the equations are linear Graph am I correct? So X is going to be X for both Equations and so I so is Y and in this case X=0 and Y=0 so X + Y = K is Really 0 + 0 = 0 and X - Y = K is really 0 - 0 = 0 So Yes You are correct :D
