satisfy that inequality, a point must be on or above the line y = 2x + 3. So
we can eliminate B, C, and E.The second inequality has a “less-than-or-equal-to” sign, so to satisfy
that inequality, a point must be on or below the line The
choice with the proper shading, then, is (D).29 . B
Plug x = 10 and y = –6 into the definition:
30 . D
Mark up the figure. Draw in not only the segment AE you’re looking for,
but also the perpendicular that makes the two right triangles as shown:Each of the interior angles of a regular hexagon measures 120°, and these
two right triangles split one of those 120° angles. That means the two
right triangles are in fact 30-60-90s:
