CharityDanielle Group Title hoose the correct description of the graph of the compound inequality x - 1 < or = to 9 or 2x > or = to 24 A number line with an open circle on 10, shading to the left, and an open circle on 12, shading to the right. A number line with an open circle on 10, an open circle on 12, and shading in between. A number line with a closed circle on 10, a closed circle on 12, and shading in between.

@dmezzullo sorry for taggiin you soo much..i know you must hate me right now ):

2. dmezzullo Group Title

Its ok idk this one

3. CharityDanielle Group Title

poo

4. satellite73 Group Title

$x-1\leq 9\iff x\leq 10$

5. CharityDanielle Group Title

huh????????????

6. satellite73 Group Title

$2x\geq 24\iff x\geq 12$

7. CharityDanielle Group Title

im confsed!!

8. satellite73 Group Title

before you can answer the question, you have to solve each inequality for $$x$$ that is the first step

9. satellite73 Group Title

the first inequality is $$x-1\leq 9$$ to solve this for $$x$$ add 1 to both sides, which gives you $x\leq 10$

10. satellite73 Group Title

to solve $$2x\geq 24$$ divide both sides by 2 and get $$x\geq 12$$

11. satellite73 Group Title

this tells you $$x\leq 10$$ OR $$x\geq 12$$

13. satellite73 Group Title

both circles are closed because you have $$\leq$$ and $$\geq$$ instead of $$<$$ and $$>$$
