Explanation of Solution
Using Gauss-Jordan method to indicate the solutions:
Consider the given system of linear equations,
The augmented matrix of this system is as follows:
The Gauss-Jordan method is applied to find the solutions of the above system of linear equations.
Replace row 3 of A|b by (row 3 – row 1), then the following matrix is obtained,
Now, replace row 3 of
This produces the following result,
Solving the above equations, the following result is obtained,
Therefore, the above system of linear equations has a unique solution.

- Briefly describe the issues involved in using ATM technology in Local Area Networksarrow_forwardFor this question you will perform two levels of quicksort on an array containing these numbers: 59 41 61 73 43 57 50 13 96 88 42 77 27 95 32 89 In the first blank, enter the array contents after the top level partition. In the second blank, enter the array contents after one more partition of the left-hand subarray resulting from the first partition. In the third blank, enter the array contents after one more partition of the right-hand subarray resulting from the first partition. Print the numbers with a single space between them. Use the algorithm we covered in class, in which the first element of the subarray is the partition value. Question 1 options: Blank # 1 Blank # 2 Blank # 3arrow_forward1.
