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:
f(5.5) = -26.5
Step-by-step explanation:
f(5.5) = -5x+1
f(5.5) = -5(5.5) +1
