Question

Please help me, please and thank youuu! :D

Answer 1

f = -
`(19)/(7)`

Explanation:

Given f varies directly with m then the equation relating them is

f = km ← k is the constant of variation

To find k use the condition f = - 19 when m = 14

- 19 = 14k ( divide both sides by 14 )

-
`(19)/(14)` = k

f = -
`(19)/(14)` m ← equation of variation

When m = 2 , then

f = -
`(19)/(14)` × 2 = -
`(19)/(7)`
