Which graph is that of the inequality shown below?
defon

All answer choices show the boundary line going through (0,-2) and (2,2). This  is because y = 2x-2 goes through these two points. We make the boundary line a dashed line to indicate that solution points are not found on the boundary (because there is no "or equal to" portion in the inequality sign).

The shading is below the boundary line because of the "less than" sign. Any solution point (x,y) will have its y coordinate smaller than the y coordinate of points on the boundary line. So if (a,b) is on the boundary, then (a,c) is a solution where c < b.

In summary, the graph has a dashed boundary line and the shading is below the boundary

A tank that measures 40 feet by 36 feet by 18 feet is filled with water to 5/6 of its height. 1/3 of the water is poured out of
rodikova [14]

so assuming the tank is just a big tall rectangular box-like tank.


well, the volume of a rectangular prism is simply the product of its length, height and width. So the volume for this one will be 40 * 36 * 18, or 25920 ft³.


if we fill that up to only 5/6, not the whole tank, how much is 5/6 of 25920? well, is really just their product, namely 21600 ft³.


and then we dump 1/3 of that 21600, how much is that anyway? well 1/3 of 21600 is really just their product, so 7200 ft³.


so we had 21600 ft³ of water, and dumped 7200 ft³, we're left only with 21600 - 7200, or 14400 ft³.
