Part 5) The maximum value of z is 110.7

Part 6) The maximum value of z is 6

Part 7) The minimum value of z is 120

Part 8 The minimum value of z is 3

Step-by-step explanation:

Part 5) Maximizes function z subject to constraints

z=5x+7y

$2x+3y\leq 45$ ----> constraints A

$x-3y\leq 2$ ---> constraints B

$x\geq 0$ ---> constraints C

$y\geq 0$ ---> constraints D

using a graphing tool

The solution is the shaded area

The vertices of the shaded area are

(0,0),(2,0),(15.7,4.6) and (0,15)

see the attached figure N 1

Substitute the value of x and the value of y of each vertex in the objective function z and then compare the results

For (0,0) ----> z=5(0)+7(0)=0

For (2,0) ----> z=5(2)+7(0)=10

For (15.7,4.6) ----> z=5(15.7)+7(4.6)=110.7

For (0,17) ----> z=5(0)+7(15)=105

therefore

The maximum value of z is 110.7

Part 6) Maximizes function z subject to constraints

z=2x+y

$y\leq x+2$ ----> constraints A

$y\leq -x+3$ ---> constraints B

$x\geq 0$ ---> constraints C

$y\geq 0$ ---> constraints D

using a graphing tool

The solution is the shaded area

The vertices of the shaded area are

(0,0),(3,0),(0.5,2.5) and (0,2)

see the attached figure N 2

Substitute the value of x and the value of y of each vertex in the objective function z and then compare the results

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

For (3,0) ----> z=2(3)+(0)=6

For (0.5,2.5) ----> z=2(0.5)+(2.5)=3.5

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

therefore

The maximum value of z is 6

Part 7) Minimize function z subject to constraints

z=2x+2y

$x+2y\geq 80$ ----> constraints A

$3x+2y\geq 160$ ---> constraints B

$5x+2y\geq 200$ --> constraints C

$x\geq 0$ ---> constraints D

$y\geq 0$ ---> constraints E

using a graphing tool

The solution is the shaded area

The vertices of the shaded area are

(0,100),(20,50),(40,20) and (80,0)

see the attached figure N 3

Substitute the value of x and the value of y of each vertex in the objective function z and then compare the results

For (0,100) ----> z=2(0)+2(100)=200

For (20,50) ----> z=2(20)+2(50)=140

For (40,20) ----> z=2(40)+2(20)=120

For (80,0) ----> z=2(80)+2(0)=160

therefore

The minimum value of z is 120

Part 8) Minimize function z subject to constraints

z=7x+3y

$3x-y\geq -2$ ----> constraints A

$x+y\leq 9$ ---> constraints B

x-y=-1 --> constraints C

$x\geq 0$ ---> constraints D

$y\geq 0$ ---> constraints E

using a graphing tool

The solution is the line segment (0,1) to (4,5)

see the attached figure N 4

Substitute the value of x and the value of y of each endpoint in the objective function z and then compare the results

For (0,1) ----> z=7(0)+3(1)=3

For (4,5) ----> z=7(4)+3(5)=43

therefore

The minimum value of z is 3
