Math Problem Statement
- Solve the following L.P.P. graphically Min Z = 6x + 2y Such that x + 2y 30 x + 2y 120 2x + y 40 x 0, y .
Solution
It seems like the inequality symbols in the constraints are missing. From the context, I will assume the constraints should look something like this:
- ,
Let's proceed to solve this Linear Programming Problem (LPP) graphically.
Steps to solve graphically:
-
Plot the lines for the constraints:
- For and , find the points of intersection with the axes.
- For , find the points of intersection with the axes.
-
Shade the feasible region:
- Identify the region that satisfies all the inequalities.
-
Identify the corner points:
- The feasible region will have corner points where the lines intersect.
-
Evaluate the objective function:
- Substitute the corner points into to find the minimum value.
I'll walk you through the solution and plot it graphically. Let's begin by solving for the points where the lines intersect the axes.
Step 1: Find the intercepts

- When , .
Thus, the intercepts are and .
For :
- When , → .
- When , .
Thus, the intercepts are and .
For :
- When , .
- When , → .
Thus, the intercepts are and .
Step 2: Plot the lines and identify the feasible region
Now we will plot these lines on a graph and find the feasible region that satisfies all the constraints.
Let me plot this graphically.
