Answer:
   C
Step-by-step explanation:
You can reflect point x across the origin to find is is just above -1. Adding 3 to that value gives a point just above -1+3 = 2. That's where point C is located.

<em>Algebraic solution</em>
Algebraically, you can set y = -x +3, and solve for x. That gives you ...
   x = 3 -y
Using the relation given at the start:
   0 < x < 1
   0 < 3 -y < 1 . . . . . substitute for x
Adding y gives ...
   y < 3 < y+1
We can separate this into two inequalities:
   y < 3, and
   3 < y+1
   2 < y . . . subtract 1
Now, we have ...
   2 < y < 3 . . . . . the location of point C
As you can see, it is much easier to use the number line directly to find the desired point.
 
        
             
        
        
        
So find the volume of the separate shapes. For rectangular prisms (which includes cubes), multiply width by height by length. So multiply 4 by 6 by 2. And for the cube, multiply 2 by 2 by 2. Then, to find the total volume, add the two together.
