Answer: -2
Step-by-step explanation:
See attached picture
X + y = 5 => 2x + 2y = 10
x - 2y = 2
_________(+)
3x = 12 => x = 12 / 3 => x = 4 => y = 5 - 4 => y = 1
The solution to the system of equations is ( 4 , 1 ).

Answer:
x > 2
Step-by-step explanation:
-1/2x + 6 < 4x - 3
Start by adding 1/2x to both sides to get both x's on the same side
6 < 4 1/2x - 3
Add 3 to both sides to keep the x's by themselves on one side
9 < 4 1/2x
Divide both sides by 4 1/2 to get x by itself
2 < x so x > 2
Answer:
The Volume is equal to 2x^3-3x^2+2x-3
Step-by-step explanation:
Formula for the volume of a rectangular prism is V=WHL
We know that:
W=x-1
L=x+1
H=2x-3
So, V= (x-1)(x-1)(2x-3)
Simplify
(x^2+1)(2x-3)
2x^3-3x^2+2x-3
