Answer

A = -28, B = 14 Explanation 1. Multiply first row by column vector A = 5 \times 4 + (-8) \times 6 2. Multiply second row by column vector B = -10 \times 4 + 9 \times 6 3. Calculate values A = 20 - 48 = -28; B = -40 + 54 = 14

Explanation

1. Multiply first row by column vector<br /> $A = 5 \times 4 + (-8) \times 6$<br />2. Multiply second row by column vector<br /> $B = -10 \times 4 + 9 \times 6$<br />3. Calculate values<br /> $A = 20 - 48 = -28$; $B = -40 + 54 = 14$
