True. a homogeneous system of four linear equations in four variables is always consistent. true. there is only one way to parametrically represent the solution set of a linear equation. false. a 4 x 7 matrix has four columns. false. multiplying a row matrix by a constant is one of the elementary row operations. False. for any matrix a, we have the equality 2a 3a=5a. true. if a is a 5×4 matrix, and b is a 4×3 matrix, then the entry of ab in the 3rd row 2nd column is obtained by multiplying the 3rd column of a by the 2nd row of b. false. for any matrix a, there exists a matrix b so that a b=0. true. If a linear system has more unknowns than equations, then it must have infinitely many solutions. false. if a and b are 2x2 matrices, then ab=ba. false. the ith row vector of a matrix product ab can be computed by multiplying a by the ith row vector of b. false. tr (ab) = tr (a)tr (b) false.
