Jack has a rectangular piece of land, the area of which is represented by a1 = 9.5l. his brother has a different rectangular piece of land, the area of which is represented by a2 = l(14 − l). let a represent the area in square meters and l represent the length in meters of the pieces of land. the two equations plotted on a graph meet at a point as shown in the image

Wrong answers will be reported! (3,7), (10, 0), (2.5, 1)1. using the vertices of the feasible region you identified in #7, tell which of the vertices maximizes, and which minimizes, the following objective equation: p=8x+3y2. why do we often use x0 and y0 as constraints in a linear programming (optimization) problem?
