if x > y and either both x, and are +ve or -ve
based on equation x = 1/2 + y => both x and y are +ve. Right?
Hi all, I'm new here but figured I'd jump right in!!
I agree with you on this one. Taking the two statements together we know abs(x) must be greater than abs(y) and that x and y are either both positive or both negative.
We also know that 2x - 2y = 1.
2(x-y) = 1
x - y = 1/2
x = 1/2 + y
There is no way abs(x) could be greater than abs(y) if x and y were both negative.
x = -2
-2 = 1/2 + y
-5/2 = y
abs(-2) < abs(-5/2)
x = -4
-4 = 1/2 + y
-9/2 = y
abs (-4) < abs(-9/2)
I'm going with C for my answer.
