If you are multiplying into a vector, do it like you would any other form of distribution. -2<5,6> = <-10,-12>. 5<-2,-6> = <-10,-30>. Now add those together: <-10,-12>+<-10,-30> = <(-10+-10),(-12+-30)> = <-20,-42> That last bracketed pair that's bolded is your answer.
Answer:
Value of -2u+5v is:
<-20,-42>
Step-by-step explanation:
We are given:
u = <5, 6> and v = <-2, -6>
We have to find the value of -2u+5v
-2u+5v= -2 <5, 6> +5 <-2, -6>
= <-10,-12>+<-10,-30>
= <-10-10,-12-30>
= <-20,-42>
Hence, Value of -2u+5v is:
<-20,-42>
