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

solution

For this case we can use the following proportion rule:

$\frac{-19}{14}=\frac{f}{2}$

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

$f=2\cdot(\frac{-19}{14})=-\frac{19}{7}$
