(1 point) Which of the following statements are true? There may be more than one true statement. A. If the columns of the matrix A form a linearly independent set, then the equation Ax=b is consistent. B. If the echelon form of the augmented matrix [A | b] has a leading entry in every row, then the equation Ax=b is inconsistent. C. If A is an m×n matrix and if the equation Ax=b is inconsistent for some b in Rm, then the echelon form of A cannot have a leading entry in every row. D. Every matrix equation Ax=b corresponds to a vector equation with the same solution set. E. If A is an m×n matrix whose columns do not span Rm, then the equation Ax=b is inconsistent for some b in Rm. F. The solution set of a linear system whose augmented matrix is [a1 a2 a3 | b] is the same as the solution set of Ax=b, if A=[a1 a2 a3 ].
