Answer 8

f(x) = kx
when x = 20
f(x) = 6
get k
plug it in the equation

Answer 9

?

Answer 10

fx=10/3x is that right

Answer 11

@John_ES is that right

Answer 12

It is just the inverse. 3/10

Answer 13

so f(x)=3/10x is the answer

Answer 14

\[f(x)=m\cdot x\Rightarrow 6=m\cdot 20\Rightarrow 6/20=m\Rightarrow 3/10=m.\]

Answer 15

ok ty

Answer 16

Yes, that is the answer.
