Question

if xy > 0, then

• A. x > 0 and y > 0
• B. x < 0 and y > 0
• C. x < 0 and y < 0
• D. x > 0 and y < 0

Answer 1

Answer: (A), (C)

The correct options are
A

x > 0 and y > 0

C

x < 0 and y < 0

The product of two positive integers or two negative integers is a positive integer.

E.g: If x = 2 and y = 3

Than, x $\times$ y = 2 $\times$ 3 = 6 (Positive integer)

If x = -2 and y = -3

Than, x $\times$ y = -2 $\times$ -3 = 6 (Positive integer)
