Answer to Problem 39E
The solutions of the system of equations are
Explanation of Solution
Given:
Calculation:
Consider the system of equations.
In order to solve the system in graphing method, solve for y in terms of x.
And the second equation is,
The system of equations becomes
Find the intersect points:
Enter the equations in graphing calculator as follows.
Set the windows as follows.
To get the graph of the equations, press GRAPH button.
To find the intersection points, press
Then confirm the first and second curves by using the right and left buttons.
Find the other intersect point.
From the screen shots, the intersection points are,
Hence, the solutions of the system of equations are
Conclusion:
Hence, the solutions of the system of equations are
