For problems 3–5 below, a triangular or quadrilateral region is defined by the system of inequalities listed.
a. sketch the region.
b. determine the coordinates of the vertices.
c. find the perimeter of the region rounded to the nearest hundredth if necessary.
d. find the area of the region rounded to the nearest tenth if necessary.
3. 8x − 9y ≥ −22 x + y ≤ 10 5x − 12y ≤ −1
4. x + 3y ≥ 0 4x − 3y ≥ 0 2x + y ≤ 10
5. 2x − 5y ≥ −14 3x + 2y ≤ 17 2x − y ≤ 9 x + y ≥ 0
