Answer:
b. n-4
Step-by-step explanation:
a number=n
4 less than it =n-4
We can factor out a 1 from -3 to get .
We know from simple arithmetic that .
So, our answer is
13.5 is your answer, here u are
Subtract corresponding x and y components
- u - v = - <- 8, 4> - <2, 7> = <8, - 4> - <2, 7> = <8 - 2, - 4 - 7> = <6, - 11>
u - v = <- 8, 4> - <2, 7> = <- 8 - 2, 4 - 7> = <- 10, - 3>
v - u = <2, 7> - <- 8, 4> = <2 + 8, 7 - 4> = <10, 3>
