Answer 2

I think it's either C or D

Answer 3

y = kx

Plug in what we know:

4 = k(12)

4 = 12k

Divide 12 to both sides

Answer 4

professor please

Answer 5

xD

Answer 6

One second

Answer 7

direct variation: \(y=kx\)

indirect variation: \(y=\dfrac{k}{x}\)

Answer 8

Okay one second sorry xD

Answer 9

\(k = \dfrac{4}{12}\)

Simplify 4/12

Answer 10

0.3333333? Thats what i got

Answer 11

or 1/3
