Sketch the graph of the solution set of system of inequalities and label it
Answer to Problem 36E
The first inequality will be away from the origin and the second inequality region will be towards the origin.
Explanation of Solution
Given:
The system of linear inequalities is:
Make the constant positive for the both inequalities by reversing the sign
Whenever the right hand side has only the positive constants, the inequality is less than or less than equal to then the region will be towards the origin and when the inequality is more than or more than equal to then the region will be away from the origin, here the first one will be away from the origin and the second inequality region will be towards the origin.
To find the point of intersection solve equations:
Multiply equation (1) by 5 and subtract from equation (2)
Putting value of y in equation (1)
The point of intersection is
The graph which shows the point of intersection is as follows:
