Perform the indicated row operations on the following matrix

Perform the indicated row operations on the following matrix. [1 -5 4 2 2 5] (-2)R_1 + R_2 rightarrow R_2 [-2 10 -8 2 12 -5] [1 -5 4 0 12 -3] [0 12 -3 2 2 5] [-2 10 -8 0 12 -3] Perform the operation, if possible. [-9 1 2 5] + [6 2 2 -3] [-3 -3 4 2] [3 3 4 2] [-3 -7 -7 -12] --3 3 4 2] Write the word or phrase that best completes each statement or answers the question. Let A = [0 -2 1 4 -1 0] and B = [1 -2 0 1 -2 -1]. Find AB. Choose the one alternative that best completes the statement or answers the question Solve the system as matrix equations using inverses. -2x_1 + 6x_2 = 6 3x_1 + 2x_2 = 13 (-3, -2) (-2, -3) (3, 2) (2, 3) Provide an appropriate response. Determine the value of each variable. [x+3 y+4 7 -1] = [6 0 7 k] x = 6 y = 0 k = -1 x = -3 y = 4 k = -1 x = 3 y = -4 k = -1 x = -3 y = -4 k = -1 x = -3 y = -4 k = -1

Solution

10) Option D) is correct

11) Option D) is correct

12) AB = [-2 -3]

[4 -9]

13) Option C) is correct

14) Option C) is correct

x + 3 = 6 ======> x = 3

y + 4 = 0 =====> y = -4

k = -1
