Write a vector equation LEHEHEHEI y+ that is equivalent to the system of equations: -5 x 6 x + 2x + x+ 2 y 6 y 4 y T I + 5 z = 3 z 8 z = = -4 2 2 =

AH expressed as a combination of vectors is: 6 Oc-a Oa + c O a à - c O-a-c C F H G 2

Consider the three equations: - 2y = -1,3x4z = -1 and 2x + 2y + z = 2. Write these in the form of Ax = b. Which of the following are true of the matrices A and b? A22 = 0 A31 = -2 b₂ = -1 b3 = 2 A13 = 0

Use the figure at the right. Determine whether the given statement is true or false. F+E=C+D g SITTE K C 14. LA 0 Q Is the statement F+E=C+D true or false? OA. False; because vector F+E moves 16 units horizontally and 1 units vertically, and vector C+D moves 6 units horizontally and -5 units vertically OB. True, because vector F+E moves 16 units horizontally and 1 units vertically, and vector C+D moves 16 units horizontally and 1 units vertically OC. True, because vector F+E moves 6 units horizontally and 1 units vertically and vector C + D moves 6 units horizontally and 1 units vertically. OD. False, because vector F+E moves 6 units horizontally and -5 units vertically, and vector C + D moves 16 units horizontally and 1 units vertically.
