# Use the row reduction algorithm to transform the matrix into echelon form or reduced echelon form as indicated. 3) Find the echelon form of the given matrix. [1 -3 2 4 -11 2 -2 9 5 3 -5 -1] A) [1 0 0 4 1 0 -2 3 27 3 4 17] B) [1 0 0 4 1 -6 -2 3 9 3 4 -7] C) [1 0 0 4 1 0 -2 3 27 3 4 0] D) [1 0 0 4 1 0 -2 3 15 3 4 -1] Solve the problem. 4) Let a_1 = [3 4 -4], a_2 = [-4 1 1], and b = [2 -10 6]. Determine whether b can be written as a linear combination of a_1 and a_2. In other words, determine whether we x_1 and x_2 exist, such that x_1 a_1 + x_2 a_2 = b. Determine the weights x_1 and x_2 if possible. A) x_1 = -1, x_2 = -3 B) x_1 = -2, x_2 = -2 C) x_1 = -2, x_2 = -1 D) No solution Show transcribed image text
