Question

Given vectors a = <9, 9> and b = <–4, 7>, find 3a − 2b

Answer 1

Answer:

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:

$3a-2b\\=3-2\\=+\\=\\=$

This is the vector after the operations shown.
