Answer

Explanation:

Step1: Find intersection points

  1. Intersection of (x + 2y=10) and (y = 2): Substitute (y = 2) into (x+2y=10), we get (x+2\times2=10), so (x=10 - 4=6). The point is ((6,2)).
  2. Intersection of (x + 2y=10) and (x = 0): Substitute (x = 0) into (x+2y=10), we get (2y=10), so (y = 5). The point is ((0,5)). But since (y\leq2), this intersection point is not in the feasible - region.
  3. Intersection of (x + 2y=10) and (y = 0): Substitute (y = 0) into (x+2y=10), we get (x=10). The point is ((10,0)).
  4. Intersection of (y = 2) and (x = 0): The point is ((0,2)).
  5. Intersection of (y = 2) and (y = 0) is not a valid intersection for the feasible - region.
  6. Intersection of (x = 0) and (y = 0): The point is ((0,0)).

Step2: Evaluate (P = 4x+2y) at intersection points

  1. At ((0,0)): (P=4\times0 + 2\times0=0).
  2. At ((0,2)): (P=4\times0+2\times2 = 4).
  3. At ((6,2)): (P=4\times6+2\times2=24 + 4=28).
  4. At ((10,0)): (P=4\times10+2\times0=40).
