jawaban yang benar adalah B. 

Pembahasan

Diketahui dan Ditanyavektor yang memenuhi operasi ? Dengan operasi penjumlahan vektor untuk mencari vektor : Dengan demikian,vektor yang memenuhi operasi adalah . Oleh karena itu, jawaban yang benar adalah B.

Diketahui straight a with rightwards arrow on top equals 3 straight i with rightwards arrow on top plus 5 straight j with rightwards arrow on top equals open parentheses table row 3 row 5 end table close parentheses dan straight b with rightwards arrow on top equals 4 straight i with rightwards arrow on top minus straight j with rightwards arrow on top equals open parentheses table row 4 row cell negative 1 end cell end table close parentheses

Ditanya vektor table attributes columnalign right center left columnspacing 0px end attributes row blank blank cell straight c with rightwards arrow on top end cell end table yang memenuhi operasi 3 table attributes columnalign right center left columnspacing 0px end attributes row blank blank cell straight b with rightwards arrow on top end cell end table plus 2 table attributes columnalign right center left columnspacing 0px end attributes row blank blank cell straight c with rightwards arrow on top end cell end table equals table attributes columnalign right center left columnspacing 0px end attributes row blank blank cell straight c with rightwards arrow on top end cell end table minus 2 table attributes columnalign right center left columnspacing 0px end attributes row blank blank cell straight a with rightwards arrow on top end cell end table ?

Dengan operasi penjumlahan vektor untuk mencari vektor table attributes columnalign right center left columnspacing 0px end attributes row blank blank cell straight c with rightwards arrow on top end cell end table :

table attributes columnalign right center left columnspacing 0px end attributes row cell 3 straight b with rightwards arrow on top plus 2 straight c with rightwards arrow on top end cell equals cell straight c with rightwards arrow on top minus 2 straight a with rightwards arrow on top end cell row cell 2 straight c with rightwards arrow on top minus straight c with rightwards arrow on top end cell equals cell negative 2 straight a with rightwards arrow on top minus 3 straight b with rightwards arrow on top end cell row cell straight c with rightwards arrow on top end cell equals cell negative 2 open parentheses table row 3 row 5 end table close parentheses minus 3 open parentheses table row 4 row cell negative 1 end cell end table close parentheses end cell row blank equals cell open parentheses table row cell negative 6 end cell row cell negative 10 end cell end table close parentheses minus open parentheses table row 12 row cell negative 3 end cell end table close parentheses end cell row blank equals cell open parentheses table row cell negative 18 end cell row cell negative 7 end cell end table close parentheses end cell row cell straight c with rightwards arrow on top end cell equals cell negative 18 straight i with rightwards arrow on top minus 7 straight j with rightwards arrow on top end cell end table

Dengan demikian, vektor straight c with rightwards arrow on top yang memenuhi operasi 3 table attributes columnalign right center left columnspacing 0px end attributes row blank blank cell straight b with rightwards arrow on top end cell end table plus 2 table attributes columnalign right center left columnspacing 0px end attributes row blank blank cell straight c with rightwards arrow on top end cell end table equals table attributes columnalign right center left columnspacing 0px end attributes row blank blank cell straight c with rightwards arrow on top end cell end table minus 2 table attributes columnalign right center left columnspacing 0px end attributes row blank blank cell straight a with rightwards arrow on top end cell end table adalah negative 18 straight i with rightwards arrow on top minus 7 straight j with rightwards arrow on top.

Oleh karena itu, jawaban yang benar adalah B.
