scalar multiplication, now, add them up
scalar multiplication, now, add them up
Answer:
<-20 , -42>
Step-by-step explanation:
u = <5, 6>, v = <-2, -6>
To find -2u + 5v, we use scalar multiplication
Multiply -2 with vector u
u = <5, 6>, -2u = -2<5,6> = <-10, -12>
v = <-2, -6>, 5v=5<-2, -6> = <-10, -30>
Now we do -2u + 5v
Add both the vectors we got
<-10, -12> + <-10, -30>
<-10+-10, -12-30>
<-20 , -42>
