## anonymous one year ago Choose the true statement about the graph of x < 4. closed circle on 4 and all numbers to the left shaded open circle on 4 and all numbers to the right shaded open circle on 4 and all numbers to the left shaded

1. anonymous

closed circle on 4 and all numbers to the left shaded

2. UsukiDoll

while the left shaded part is true. If we have a > or < sign, it should be an open circle

3. UsukiDoll

should we have a $\leq$ or $\geq$ we have a closed circle. I don't see those signs for x<4

4. anonymous

and if they give that like this Choose the true statement about the graph of 3x ≥ 6. closed circle on 2 and all numbers to the right shaded closed circle on 2 and all numbers to the left shaded open circle on 2 and all numbers to the right shaded open circle on 2 and all numbers to the left shaded

5. UsukiDoll

for that question, solve the inequality first. then since you have a $\geq$ we have a closed circle

6. UsukiDoll

and graph according to the point of the symbol

7. UsukiDoll

for example if I want to graph x < 2 on a number line |dw:1437999382990:dw|

8. anonymous

so it will be the second one

9. UsukiDoll

|dw:1437999408835:dw|

10. UsukiDoll

no.... not exactly... because our inequality symbol would have been $\leq$ so that shading is going to the left.

11. UsukiDoll

$3x ≥ 6.$ ok first solve this inequality by dividing 3 on both sides.

12. UsukiDoll

then we can obtain x by itself and since we have $\geq$ we should be shading to the right with a closed circle

13. UsukiDoll

I'll give a similar example suppose we are given $4x \geq 16$ solving for x by dividing both sides by 4, we get $x \geq 4$ since we have a $\geq$ sign we have a closed circle and based on the opposite direction of the symbol's mouth, we are shading to the right. |dw:1437999750344:dw|
