## DerpisTheWordOriSiT one year ago Find the solution set for the given inequality if the replacement set is {1, 2, 3, 4, 5, 6}. 3x – 5 ≥ 7 A. {1, 2, 3, 4} B. {1, 2, 3} C. {4, 5, 6} D. {5, 6} @forgiveness

Substitute all the numbers in the answers

2. DerpisTheWordOriSiT

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

3. anonymous

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

4. anonymous

So 1 doesn't work

5. DerpisTheWordOriSiT

So only C and D

6. anonymous

Yes, but C gives more data.

7. anonymous

C would be the better answer. Good Job!

8. DerpisTheWordOriSiT

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

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