The equation Ax = b is consistent if the augmented matrix [ A b ] has a pivot position in every row. Choose the correct answer below. A. False. If the augmented matrix [A b] has a pivot position in every row, the equation Ax = b may or may not be consistent. One pivot position may be in the column representing b. B. True. If the augmented matrix [A b] has a pivot position in every row, then the equation Ax = b has a solution for each b in Rm. C. True. The pivot positions in the augmented matrix [ A b ] always occur in the columns that represent A. D. False. The augmented matrix [ A b ] cannot have a pivot position in every row because it has more columns than rows.

Determine whether the statement below is true or false. Justify the answer. The echelon form of a matrix is unique. Choose the correct answer below. A. The statement is true. The echelon form of a matrix is always unique, but the reduced echelon form of a matrix might B. The statement is false. Neither the echelon form nor the reduced echelon form of a matrix are unique. They depend on the row operations performed C. The statement is false. The echelon form of a matrix is not unique, but the reduced echelon form is unique. D. The statement is true. Both the echelon form and the reduced echelon form of a matrix are unique. They are the same.
