Question If y varies directly with x and y = 48 when x = 6, find y if x = 3. First, find the direct variation equation. y = [? ]x

so this is direct proportional question so y=(k)x sub y=48 and x=648=6kk=8now you got a constant k now sub x=3 y=(8)(3)=24 Log in to Reply

so this is direct proportional question

so y=(k)x

sub y=48 and x=6

48=6k

k=8

now you got a constant k

now sub x=3

y=(8)(3)

=24
