As you can see from what I’ve drawn, 12 divided by -2 will give us -6 (12/-2=-6).
Now, ask yourself this:
3 multiplied by what makes - 6? (You have to divide) so, - 6/3= - 2. The answer is 2. So one number must be 2.
Now, what times what makes 2? 1 x 2. Since we already have 2, we just have to add 1. So the last number will be 1.

Answer:

1) x ≤ -2;

2) x > 2;

3) x - 2 < 0

4) 2 ≤ x;

5)-2 < x;

Step-by-step explanation:

≤ means equal to or smaller than;

≥ means equal to or greater than;

< means smaller than;

> means greater than;

In addition, ≤ and ≥ are closed dots in the intervals. < and > are open dots in the intervals.

1) x ≤ -2; By looking at the intervals, the dot is -2, and the arrow is going to the left sides, -4, that the numbers were in a range of smaller than -2. And also because it's a closed dot, it means equal to or smaller than.

2) x > 2; The number starts in 2 with an open dot, and goes to 4, which means x in a range that greater than 2 but not equal to.

3) x - 2 < 0, we get x < 2, by plus 2 in both sides. The number starts in 2 with an open dot and goes to -4, which means x becomes smaller than 2 but not equal to.

4) 2 ≤ x; The number starts in 2 with a closed dot and goes to 4, the x is places in a number range that is equal to or greater than 2.

5)-2 < x; The number starts in -2 with an open dot and goes to 4, which means x becomes bigger than -2 but not equal to.
