Answer:

The value that maximize the objective function is the point (1,4)

Step-by-step explanation:

we have

3x+y\leq 7 ----> inequality A

x+2y\leq 9 ----> inequality B

x\geq 0 ----> inequality C

y\geq 0 ----> inequality D

Using a graphing tool

The solution is the shaded area

see the attached figure

The coordinates of the solution area are

(0,0),(0,4.5),(1,4),(2.33,0)

we have

The Objective Function is equal to

P=2x+y

To find out the value of x and y that maximize the objective function, substitute each ordered pair of the vertices in the objective function and then compare the results

For (0,0) --------> P=2(0)+0=0

For (0,4.5) --------> P=2(0)+4.5=4.5

For (1,4) --------> P=2(1)+4=6

For (2.33,0) --------> P=2(2.33)+0=4.66

The value that maximize the objective function is the point (1,4)

Solve the system by graphing.
igor_vitrenko [27]

Answer:

Hi There the correct answer is {x,y} = {-1,-10}  

 

System of Linear Equations entered :

  [1]    3x - y = 7

  [2]    4x - 2y = 16

Graphic Representation of the Equations :

   y + 3x = 7        -2y + 4x = 16  

 

 

Solve by Substitution :

// Solve equation [1] for the variable  y  

 

 [1]    y = 3x - 7

// Plug this in for variable  y  in equation [2]

  [2]    4x - 2•(3x-7) = 16

  [2]    -2x = 2

// Solve equation [2] for the variable  x  

  [2]    2x = - 2  

  [2]    x = - 1  

// By now we know this much :

   x = -1

   y = 3x-7

// Use the  x  value to solve for  y  

   y = 3(-1)-7 = -10  

Solution :

{x,y} = {-1,-10}  

Hope it helps!
