6 x 18 x 20 = 2,160 divided by 3 equals 720
ANSWER
The constant of variation is 6.
EXPLANATION
The inverse variation equation is:

We want to find the constant of variation, when x=-3 and y=-2.
We substitute the values for x and y to get,

Multiply out the left hand keeping in mind that negative times negative yields a positive result.
This implies that;

Hence the constant of variation is 6.
15. x ≤ -24
x + 19 ≤ -5
x ≤ -24
16. z > -12
3z > -36
z > -12
17. 185 + c > 410; c > 225
18. C.
x - 6 ≥ 1
x ≥ 7
