Question: now find an augmented matrix in reduced echelon form that...

Question details

Now find an augmented matrix in reduced echelon form that represents a linear system of four equations in for variables for which the corresponding coefficient matrix has a pivot in each column. Choose the correct answer below. A. OB. 1 00 a 01 0 b 0 01 c 00 0 d 1 000 01 0 0 0 01 0 0 001 a 00 01 0 b 0 0 1 0 0 c0 000 d 1 1000 a 01 00 b 0 010 c 0 0 01d Use the augmented matrix to determine if the linear system is consistent. Is the linear system represented by the augmented matrix consistent? y A. Yes, because the rightmost column of the augmented matrix is not a pivot column. B. No, because the rightmost column of the augmented matrix is a pivot column. ° C. Yes, because the rightmost column of the augmented matrix is a pivot column. O D. Write the system of equations corresponding to the augmented matrix found above to determine the number of free variables. No, because the rightmost column of the augmented matrix is not a pivot columm.
