Unformatted text preview: 1. If a system of n linear equa tions in n unknowns is consistent, then the rank of the matrix of coef ficients is n . 1. Always true 2. Sometimes true 3. False 1 2. If the determinant of the matrix of coefficients of a system of n linear equations in n unknowns is singular, then the system has in finitely many solutions. 1. Always true 2. Sometimes true 3. False 2 2a. If 0 is an eigenvalue of the matrix of coefficients of a system of n linear equations in n unknowns, then the system has no solutions. 1. Always true 2. Sometimes true 3. False 3 3. If the reduced row echelon form of the matrix of coefficients of a system of n linear equations in n unknowns is the identity ma trix, then the matrix of coefficients is singular. 1. Always true 2. Sometimes true 3. False 4 4. If a system of n linear equa tions in n unknowns is dependent, then the rank of the matrix of coef ficients is less than n ....
