<span>get their dot product, if the dot product is 0, then they're orthogonal (
perpendicular).
also keep in mind that, if two vectors bear the same slope, namely <a,b> and <c,d> and the simplified slope b/a is the same value as d/c, then they're
parallel vectors.</span>
In order from top to bottom, your answer should be:
A
C
B
Answer:
Step-by-step explanation:
hello :
a(x) = 3x - 12 and b(x) = x-9, so
a[b(x)]=a(x-9) =3(x-9)-12
a[b(x)]=3x-9-12
a[b(x)]=3x+21
1. 12/5
2. 24/10
3. 48/20
4. 96/40
