Question 109214
"a. provide a coeffient matrix corresponding tp the system of linear equations."


Simply write the coefficients without their corresponding variables in a matrix like this:


{{{(matrix(3,3,3,-2,1,-1,1,0,0,-2,6))}}}

"B. the transpose is ? is it the switching of rows?"


The transpose simply takes every row and makes it a column and vice versa



So the first row becomes the first column and the first column becomes the first row. This is applied to each row and column


So the transpose of {{{(matrix(3,3,3,-2,1,-1,1,0,0,-2,6))}}} is {{{(matrix(3,3,3,-1,0,-2,1,-2,1,0,6))}}}

"c.The determinant? is it the part of a matrix A, det |A| or , is a real number associated with every square matrix."

The determinant of any matrix is just a scalar value (some single number)
