anyone?

hero · Answer

I suggest testing a random point in the solution region.

debbieg · Answer

Pick a point int he shaded region. Any point will do (1, 1) is an easy one.

Check it in each of the 4 choices. If it makes ALL the expressions in the choice true, then that choice is the answer.

debbieg · Answer

For only one of your answers will the point make ALL of the inequalities in that choice a true statement.

anonymous · Answer

A and B both are true

anonymous · Answer

am i missing something?

hero · Answer

Can you show the work you did for A and B?

hero · Answer

It is impossible for A and B to both be true.

hero · Answer

Try to figure out why...

anonymous · Answer

I have no idea

hero · Answer

You should post your work for A and B so that I can take a look.

debbieg · Answer

If you picked a point INSIDE the shaded region (not ON one of the lines bordering the region) then A and B can't both be true.

Certainly, if you tried the point I suggested, (1, 1), then they are not both true.
