Please see the attached image.
Step-by-step explanation:
I'm assuming you've already learnt how to draw an equation in slope intercept form. The line of an inequality is drawn the same way.
The difference is that for inequalities you will have to shade.
Basically, the inequality sign will tell you which are to shade.
Greater than will mean above the line and
Less than will be below the line.
Also, if the sign is a "or equal to" sign, then the line will be solid, if not, it's dotted.
Answer:
The side length of the cube is 9.
Step-by-step explanation:
To find the volume of a cube you use the equation V=E³, although edge can mean length.
Since we already know the volume though, we have to do this equation backwards, and find the cubed root of 729.
To do this we do which will give us our answer of 9 cubic inches.
