1 Find the inverse of the given matrix, if it exists. Use the algorithm for finding Aby row reducing [A I]. A = 10-3 41-4 -2 3-4 Set up the matrix [A I]. 10 -3 1 0 0 [AI] = 4 1 -40 10 -2 3-4 0 0 1 (Type an integer or simplified fraction for each matrix element.) Find the inverse. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. The inverse matrix is A1 = (Type an integer or simplified fraction for each matrix element.) OB. The matrix A does not have an inverse.
