Your friend is trying to find the maximum value of p = -x + 3y subject to the following four constraints.

• what error did your friend make in the graph below?

• what is the correct solution?

The maximum value of P=11 occurs at x=1 and y=4

Step-by-step explanation:

we have

----> constraint A

----> constraint B

----> constraint C

----> constraint D

using a graphing tool

The solution is the shaded area

see the attached figure

The vertices of the solution area are

(0,0),(0,3),(1,4),(3,0)

Substitute the value of x and the value of y of each vertex in the objective function , to find out the maximum value of P

The objective function is

For (0,0) ----->

For (0,3) ----->

For (1,4) ----->

For (3,0) ----->

therefore

The maximum value of P=11 occurs at x=1 and y=4

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.
