Step-by-step explanation:
Given the inequalities as
y>-2x+3
y<1/2x-2
Graph the inequalities on the graph tool
The solution is points in the shaded area such as (2,2),(4,4),(4,2),(2,-2),(2,-4)
The point (-2,3) is not included in the solution area because it is located in the un-shaded area.
Mathematically, taking points (-2,3) into the inequality
y>-2x+3
3>-2(-2) +3
3>4+3
3>7---------------------not correct because 3<7

Answer:
474.5 ft ³
Step-by-step explanation:
<u>1) Find the volume of the cube</u>
where l is the side length
Plug in 9 ft as l
Therefore, the volume of the cube is 729 ft³.
<u>2) Find the volume of the cylinder</u>
where r is the radius of the base and h is the height of the cylinder
Plug in 3 ft as the radius and 9 as the height
Therefore, the volume of the cylinder is approximately 254.5 ft ³.
<u>3) Subtract the volume of the cylinder from the volume of the cube</u>
729 ft³ - 254.5 ft ³
= 474.5 ft ³
Therefore, the volume of the figure is 474.5 ft ³.
I hope this helps!
