For this exercise assume that the matrices are all nxn. The statement in this exercise is an implication of the form "If "statement 1", then "statement 2"." Mark an implication as True if the truth of "statement 2" always follows whenever "statement 1" happens to be true. Mark the implication as False if "statement 2" is false but "statement 1" is true. Justify your answer. If the equation Ax = 0 has only the trivial solution, then A is row equivalent to the nxn identity matrix. Choose the correct answer below. OA. The statement is true. By the Invertible Matrix Theorem, if the equation Ax = 0 has only the trivial solution, then the matrix is invertible. Thus, A must also be row equivalent to the nxn identity matrix. OB. The statement is false. By the Invertible Matrix Theorem, if the equation Ax = 0 has only the trivial solution, then the matrix is not invertible; this means the columns of A do not span Rn. Thus, A must also be row equivalent to the nxn identity matrix. C. The statement is true. By the Invertible Matrix Theorem, if equation Ax = 0 has only the trivial solution, then the equation Ax = b has no solutions for each b in Rn. Thus, A must also be row equivalent to the nxn identity matrix. O D. The statement is false. By the Invertible Matrix Theorem, if the equation Ax = 0 has only the trivial solution, then the matrix is not invertible. Thus, A cannot be row equivalent to the nxn identity matrix.
