A: -.12x^2 + 2.11x + 4.22
B: -6x^2 + 1.06 + 79
C: -.06x^2 + 1.06x + 7.9
D: -18x^2 + 2.11x + 4.21

answer: 486in^2

step-by-step explanation:

the correct answer is b.

this is because an open circle means < or > & since the line goes left it is < -3.

the next one has a filled circle so it can only be ≥ or ≤ and since the line goes right from 1 it is ≥ 1

hope that

sometimes it can be so they can fit in with a certain group, and others are just like that because of their personality.

option a is correct.

only one solution to the system of equations

step-by-step explanation:

if the graph of the equations do not intersects(i.,e if they are parallel) then, there are no solutions that are true for both the equations.

if the graph of the equations intersects, then there is one solution and that is true for both the equations.

since, in the given figure:

the two lines intersect each other

⇒there is only one solution which satisfy both the lines of an equations.

therefore, there is only one solution to the system of equation
