Answer:
None of the options are correct, the correct answers are: x = 0.967 and -2.067
Step-by-step explanation:

Comparing this equation with 
a = 1, b = 1.1, c = -2
Using the almighty formula for solving quadratic equation:

1 7/12 becuase 2 neg is a neg, 1 neg and 1 pos is which is bigger in this case it is pos.
Answer:
No
Step-by-step explanation:
A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line). This article reviews all three cases. One solution. A system of linear equations has one solution when the graphs intersect at a point.
