Question

if "f" varies directly with "m" and f = -19 when m=14, what is "f" when m=2? enter the number that belongs in the green box. reduce to the simplest form. f= - ?/?

Answer 1

For this case we can use the following proportion rule:

`(-19)/(14)=(f)/(2)`

Then we can solve for f on this way and we got:

`f=2\cdot((-19)/(14))=-(19)/(7)`
