=3y-11, 4x-3y=-26 Substitution
3x+4y=12
9x-2y=15
we will use elimination
multiply 3x+4y=12 by -3
-9x-12y=-36
9x-2y=15
_________ add
-14y=-21
÷-14 both sides
y=1.5
find x
3x+4 (1.5)=12
3x+6=12
-6 both sides
3x=6
÷3 both sides
x=2
x=2
y=1.5

Answer:
The volume of a cube with side length 2 is 8.
Step-by-step explanation:
The argument of the function is the side length. In v(2), the argument is 2, so the side length of the cube of interest is 2 units.
The value of the function is the volume of the cube. The value of v(2) is 8, so that is the volume of the cube whose side length is 2.
