Question

Suppose f varies inversely with g and that f = 45 when g = 6 . What is the value of f when g = 9?

Answer 1

Answer:

30

Step-by-step explanation:

f=k/g

45=k/6

k=6[45] =270

f=270/g  

=270/9=30

Answer 2

$\mathfrak{\huge{\red{ANSWER}}}$

$f = \frac{k}{g}$

$45 = \frac{k}{9} \\ \\ = \geqslant k = 405$
