The answer would be x^3 + x^2 - x - 1
Given system:
-2x-y=1 ....................(1)
-4x-2y=-1 ..................(2)
2*(1) -(2)
-4x-2y +4x+2y = 2-(-1)
0=3 => there is no solution because the two lines (equations) are parallel and distinct (never meet), so no solution.
Answer:
The scale factor is 
Step-by-step explanation:
we know that
The scale factor is equal to the ratio between the side length of the scale drawing to the corresponding side length in the actual
so
(0, 2 )
to find the y-intercept, let x = 0 in the equation
x = 0 , then 10y = 20 ⇒ y = 2 ← ( y- intercept ) ⇔ (0, 2 )
