A system of linear equations can have exactly two solutionsFalse, Either 0,1, or infinity solutions The reduced row echelon form of a matrix is uniqueT The columns of any 2 x 3 matrix are linearly dependentT Each column of the matrix produce AB is a linear combination of the columns of BF Every 2 x 2 matrix which is not the zero matrix is invertibleF If A and B are both 4 x 4 matrices, and det A = 7 and det B = π, then det(B^tA^T) = 7πT

If A and B are invertible nxn matrices, then the product AB is also invertible. - True If Ax = 0 for some x =/= 0, then the matrix A is not invertible. - True If matrix A is row reduced to echelon form to produce matrix E, then the column spaces of A and E have the same dimension. - True Any set of vectors which span all of R3 is automatically a basis for R3. - False If λ=0 is an eigenvalue of A, then the matrix A is non-singular. - False If A and B are nxn matrices and det(AB) =/= 0, th...
