n 2. (each lpt] Let A be a nxn square matrix. Mark True of False. (-1pt if the answer is wrong) (a) The inverse of an upper triangular matrix is a lower triangular matrix. (b) det(-A)=-det(A). (c) If A has no inverse, the system Ax=b has no solution. (d) Any homogeneous system of linear equations has at least one solution. (e) The inverse of an elementary matrix is an elementary matrix. (f) A" has the same eigenvalues and eigenvectors as A. (g) If x and are the eigenvectors of A corresponding to distinct eigenvalues and 12, respectively, x, and x are orthogonal. (h) If A has real eigenvalues, then A is symmetric
