Augmented Matrix a coefficient matrix with an extra column containing the constant terms Consistent system a system of equations or inequalities that has at least one solution Is the statement "Every elementary row operation is reversible" true or false? True, because replacement, interchanging, and scaling are all reversible. Is the statement "A 5×6 matrix has six rows" true or false? False, because a 5×6 matrix has five rows and six columns.

If the columns of A are linearly dependent Correct Answer Then the matrix is not invertible and an eigenvalue is 0 Note that A−1 exists. In order for λ−1 to be an eigenvalue of A−1, there must exist a nonzero x such that Upper A Superscript negative 1 Baseline Bold x equals lambda Superscript negative 1 Baseline Bold x . A−1x=λ−1x. Suppose a nonzero x satisfies Ax=λx. What is the first operation that should be performed on Ax=λx so that an equation similar to the one in the prev...
