1. Consider the following system: $x_1 + 2x_3 + x_5 + 4x_6 = 8$ $2x_2 - 2x_4 - 4x_5 - 6x_6 = 6$ $x_3 + 2x_6 = 12$ $3x_1 + x_4 + 5x_5 + 3x_6 = -6$ $-2x_2 = 2$ $x_1 + 2x_2 - x_3 + 2x_4 = 1$ (1) (a) (5 points) Put the above system into matrix form $A\vec{x} = \vec{b}$. Use Matlab's rref function to determine the reduced row echelon form of A. Now, knowing the RREF of A, write down the basis for the solution space to the system. (b) (10 points) Using Matlab's inv function, solve the system of equations. Compare this result to the solution you obtained in (a). What do you notice? Explore the warnings that Matlab gives you.

For each of the following statements, decide if it is true or false: Statement Any two eigenvectors for the same eigenvalue $\lambda$ must be linearly dependent. Any eigenvalue has infinitely many eigenvectors. If A is similar to B and B is diagonalizable then A is diagonalizable. Let A be invertible; then each eigenvalue of A is also an eigenvalue of $A^{-1}$. Let A be invertible; then each eigenvector of A is also an eigenvector of $A^{-1}$. The sum of two eigenvectors of A is also an eigenvector for A. If A is not diagonalizable then A has complex eigenvalues. True or false
