## Gabylovesyou 3 years ago Choose the correct description of the graph of the compound inequality x - 1 </= 9 or 2x >/= 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 a closed circle on 10, shading to the left, and a closed 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.

try drawing it yourself, lets see what you get..

2. baldymcgee6

Just by looking at it, you know that both circles have to be filled in.. right?

3. Gabylovesyou

yea so its between B and D right?

4. etemplin

after you know that, you can simplify each one individually, find the spot where each circle goes, and plug in a value into one of them to see if that value works. If it does shade in the direction of the value, if not shade in the other direction. Repeat for the other inequality by finding the value and shading

5. baldymcgee6

right, you just have to figure out which way it is shaded

7. baldymcgee6

You can complete the number line, just look to see which way the shading points

8. Gabylovesyou

in between ... right?? @etemplin @baldymcgee6

9. baldymcgee6

no...

10. etemplin

no

try plugging in 0 into x<=10. does it satisfy the inequality? it does, so you must shade in the direction of 0 starting at 10. Similarly, plug 0 into x>=12. it doesnt work, so you shade the other way

13. baldymcgee6

it reads "x is less than or equal to ten" and "x is greater than or equal to twelve"

14. Gabylovesyou

ohh its B ?

15. etemplin

yes
