Answer 9

anyone?

Answer 10

please?

Answer 11

Well, you see...D looked like it works, but it doesn't. I'll show you.

2x + y > 0 and -2x - y > -8
(-1,-1)

2(-1) - 1 > 0
-2 - 1 > 0
-3 > 0...no

-2(-1) + 1 > -8
2 + 1 > -8
3 > -8...which is correct

If you follow the same steps for the other choices, you see that they work, too.

Answer 12

you are correct ,no pair satisfy the given condition.
