Diketahui vektor

table attributes columnalign right center left columnspacing 0px end attributes row cell a with rightwards arrow on top end cell equals cell open parentheses table row 5 row cell negative 8 end cell end table close parentheses end cell row cell b with rightwards arrow on top end cell equals cell open parentheses table row cell negative 4 end cell row 3 end table close parentheses end cell row cell c with rightwards arrow on top end cell equals cell open parentheses table row 6 row 12 end table close parentheses end cell end table

Vektor d with rightwards arrow on top adalah hasil dari operasi hitung ketiga vektor di atas, maka

table attributes columnalign right center left columnspacing 0px end attributes row cell d with rightwards arrow on top end cell equals cell 2 a with rightwards arrow on top minus b with rightwards arrow on top plus 1 over 6 c with rightwards arrow on top end cell row blank equals cell 2 open parentheses table row 5 row cell negative 8 end cell end table close parentheses minus open parentheses table row cell negative 4 end cell row 3 end table close parentheses plus 1 over 6 open parentheses table row 6 row 12 end table close parentheses end cell row blank equals cell open parentheses table row cell 2 times left parenthesis 5 right parenthesis end cell row cell 2 times left parenthesis negative 8 right parenthesis end cell end table close parentheses minus open parentheses table row cell negative 4 end cell row 3 end table close parentheses plus open parentheses table row cell 1 over 6 times left parenthesis 6 right parenthesis end cell row cell 1 over 6 times left parenthesis 12 right parenthesis end cell end table close parentheses end cell row blank equals cell open parentheses table row 10 row cell negative 16 end cell end table close parentheses minus open parentheses table row cell negative 4 end cell row 3 end table close parentheses plus open parentheses table row 1 row 2 end table close parentheses end cell row blank equals cell open parentheses table row cell 10 minus left parenthesis negative 4 right parenthesis plus 1 end cell row cell negative 16 minus 3 plus 2 end cell end table close parentheses end cell row blank equals cell open parentheses table row 15 row cell negative 17 end cell end table close parentheses end cell end table

Dengan demikian, vektor d with rightwards arrow on top equals open parentheses table row 15 row cell negative 17 end cell end table close parentheses.

Oleh karena itu, jawaban yang benar adalah B.
