- True or False? In Exercises 73 and 76, determine whether each statement is true or false. If a statement is true, give a reason or cite an appropriate statement from the text. If a statement is false, provide an example that shows the statement is not true in all cases or cite an appropriate statement from the text. a If an mn matrix B can be obtained from elementary row operations on an mn matrix A, then the column space of B is equal to the column space of A. b The system of linearity equations Ax=b is inconsistent if and only if b is in the column space of A.arrow_forwardProof Let A be a nonsingular matrix. Prove that if B is row-equivalent to A, then B is also nonsingular.arrow_forwardDetermine Symmetric and Orthogonal Matrices In Exercises 25-32, determine wheter the matrix is symmetric, orthogonal, both, or neither.

- Proof Prove that the main diagonal of a skew-symmetric matrix consists entirely of zeros.arrow_forwardDetermine Whether Two Matrices Are Similar In Exercises 21-24, determine whether the matrices are similar. If they are, find a matrix P such that A=P1BP. A=[100020002],B=[133353331]arrow_forwardTrue or False ? In Exercise 73-76, determine whether each statement is true or false. If a statement is true, give a reason or cite an appropriate statement from the text. If statement is false, provide an example that shows the statement isnt rue in all case or cites an appropriate statement from the text. a The column space of matrix A is equal to the row space of AT. b The row space of a matrix A is equal to the column space of AT.arrow_forward
