Answer:
[tex]<35,13>[/tex]
Step-by-step explanation:
Lets review vector properties:
Let vector A=<a,b> and B=<c,d> and let "c" be a constant, then:
- cA = c<a,b> = <ca,cb>
- A+B = <a,b> + <c,d> = <a+c,b+d>
Now, let's do the vector operation shown:
[tex]3a-2b\\=3<9,9>-2<-4,7>\\=<27,27>+<8,-14>\\=<27+8,27-14>\\=<35,13>[/tex]
This is the vector after the operations shown.
