Answer:
It is A because if you make an imaginary line at x=1 then you can see that answer A just flips over the imaginary line.
Step-by-step explanation:
4x + 160y = 120
and
1x + 240y = 80
that will be be the equations. if we multiply the bottom equation by 4 we get:
4x + 960y = 320
now subtract one equation from another:
4x + 160y = 120
-(4x + 960y = 320)
and get:
-800y = -200
y = $0.25
now plug this into one equation
x +240(.25) = 80
x + 60 = 80
x = $20
so $20 per day and $0.25 per mile

Answer:
(x, y) =(-4,10)
Step-by-step explanation:
6x+2y=-4
3x+2y=8 /*(-1)
6x+2y=-4 (1)
-3x-2y=-8 (2)
6x+2x=-4
(1)+(2) 3x=-12
6x+2x=-4
x=-12/3
6x+2y=-4
x=-4
6*(-4)+2y=-4
x=-4
-24+2y=-4
x=-4
2y=-4+24
x=-4
2y=20 y=20/2 y=10
(x,y)=(-4,10)
-9y + 3 is the answer to your Simplify equation
