Chapter 6-Question15-Linear Inequalities Fig 6.5

Answer:

Question 16:

Show that the following system of linear inequalities has no solution

Answer:

let՚s plot the region of each inequality and then find the common region of all

Common Region
x31
y01

Also, satisfies the , hence region is towards the origin

Line:

Common Region
x04
y30

Also, satisfies the , hence region is towards the origin

implies that region is right to the y-axis and implies that region is up above the line ,

Question 17:

Solve the following system of linear inequalities:

Answer:

let՚s plot the region of each inequality and then find the common region of all

Common Region
x08
y120

Also, doesn՚t satisfy the , hence region is away from the origin

Line:

Common Region
x05
y150

Also, satisfies the , hence region is towards the origin

implies that region is right to the line ,

Question 18:

Show that the solution set of the following system of linear inequalities is an unbounded region

Answer:

let՚s plot the region of each inequality and then find the common region of all

Line:

Common Region
x08
y40

Also, doesn՚t satisfy the , hence region is away from the origin

Line:

Common Region
x010
y50

Also, doesn՚t satisfy the , hence region is away from the origin
