2. Use the row reduction algorithm to find the row reduced echelon form of the matrix. Find the general solution specifying the basic and free variables). 1 -7 0 6 5 0 0 1 -2 -3 7 -4 2 3. Determine if b is a linear combination of a?, a2 and a3 a? = -2 5 a3 = b = 11 , a2 = 2 5 4. Write the augmented matrix for the linear system that corresponds to the matrix equation Ax = b. Then solve the equation and write the solution as a vector. 1 2 1 A = +8+0 -3 -1 2 b= 5 3 5. Describe the solutions of Ax = 0 in parametric vector form. A = 6 -26 -2 -9 5 1 -6
