Matrices A and B are row equivalent. Choose one mathematical statement that can be made concerning the properties of the matrix 0 -7 -71 4 -7 -7 -6 1 11 1 0.5 -1.5 A = B = 0 -4.95 -4.75 0 0.0404 7 -5 10 19 -1 3 -1. Selected Answer: A is invertible because there are no rows of all zeros in B. Answers: A is invertible because there are no rows of all zeros in B. A is not invertible because B has no free variables. A is invertible because A has four pivots. All of the above. None of the above.
