Answer

$ a. \left[ {\begin{array}{cc} -4 \\ 1.5 \\ -16 \\\ \end{array} } \right] $ $ b. \left[ {\begin{array}{cc} 1 & 1\\ 2.5 & 10 \\ \end{array} } \right] $

Work Step by Step

Add corresponding elements. a. $5 - 9 = -4$ $3.2 - 1.7 = 1.5$ $-4.9 - 11.1 = -16$ Subtract corresponding elements. b. $ -4 + 5 = 1$ $0 + 1 = 1$ $3 - 0.5= 2.5$ $7 + 3 = 10$
