## ihavemathquestions 2 years ago Solve the compound inequality. Graph the solution. –8 ≤ 2x – 4 < 2

I would leave the -8 and add the 4 from the 2x-4 to the <2 What would you get?

3. Kitt020912

That's only the first step(:

4. ihavemathquestions

2x < 2

5. Kitt020912

Not quite. |dw:1361036597370:dw| Then what would you do?

6. ihavemathquestions

2x <14

7. ihavemathquestions

-2 ≤ x 3

8. Kitt020912

It's a double inequality so it's going to look like\[[ ] \le x <[ ]\]

so you need to get x by itself, to do that you have to divide everything by 2. |dw:1361036855393:dw| Then what would you get?

kitt, you made a mistake, you cant just add 4 to the right side and middle you must do it to the entire inequality including the left side this would of course change the answer you gave

@ihavemathquestions kitt's process if fine except for the 1st step just follow it can you'll get the answer

so if you dived that out you should get the right answer(: the inequality signs don't change because you aren't multiplying or dividing by a negative number.

@completeidiot thank you for catching my mistake.
