Question

Graphically, a point is a solution to a system of two inequalities if and only if __________.
A.
the point lies in the shaded region of the top inequality, but not in the shaded region of the bottom inequality
B.
the point lies in the shaded region of the bottom inequality, but not in the shaded region of the top inequality
C.
the point lies in the shaded regions of both the top and bottom inequalities
D.
the point does not lie in the shaded regions of the top or bottom inequalities

Answer 1

Im pretty sure it's C

Answer 2

how did u find that's c, because i want to undrestand the way, please

Answer 3

For an inequality the solution lies in a shaded region.

So for the first inequality there will be a shaded region and for the second inequality there will be a shaded region too. Solutions that satisfy both inequality will lie in the overlapped shaded region.

Answer 4

intersection set you may say
