Okay, this may take a while, I'll check them all.

anonymous · Answer

When you substitute 1, you end up with:

3 x 1 - 5

3 - 5

-2

anonymous · Answer

So 1 doesn't work

derpisthewordorisit · Answer

So only C and D

anonymous · Answer

Yes, but C gives more data.

anonymous · Answer

C would be the better answer. Good Job!

derpisthewordorisit · Answer

Okay! Just 2 more and we're all done.

anonymous · Answer

$$3x-5\ge7$$
$$3x \ge7+5$$
$$x \ge \frac{ 12 }{ 3 }$$
$$x \ge 4$$
solution is ?
