Answer:
C. x - y > x
Step-by-step explanation:
You can compare the values of these expressions by using numerical values for x and y.
__
We can let x = 1 (a positive integer), and y = -1 (a negative integer).
A
y > x + y
-1 > 1 + (-1)
- 1 > 0 . . . . . . false
B
y < xy
-1 < (1)(-1)
-1 < -1 . . . . . . false
C
x - y > x
1 - (-1) > 1
2 > 1 . . . . . . true
D
-xy < x
-(1)(-1) < 1
1 < 1 . . . . . . . false
