Answer:
C
Step-by-step explanation:
a=12,b= 9, c=7
x=-9±√9²-4x12x7/2x12
=-9±√81-336/24
=-9±√-225/24
{x=9+í√225/24 or x=9-í√225/24}

Step-by-step explanation:
A: The graph of the system is all points in the graph that suit 4x-2<y</=-5/2x-2
B: The point (-2,-2) is not included in the solution area. While it suits the second equation, it doesn't suit the first, ruling it out as a possible solution. If you plug in -2 as both y and x in the equation 4x-2>y, you'll get -8>-2, which is false. So, it is not a solution.
Answer:
y =

Some of the points on the graph are: (0,-3.2),(-8,0),(2,-4), and (-3,-2)
