u just posted a similar question b4... and its not that much of a challenge

Then why don't you answer it hotshot?

ok i will

Find the equation of the locus of a point that moves so that it is equidistant from the line

3x+4y-5=0
5x+12y-1=0

let P(x,y) be a point on the locus

D=|3x+4y-5|/root(25)

D=|5x+12y-1|/root(169)

13|3x+4y-5| = 5|5x+12y-1|

13(3x+4y-5)=5(5x+12y-1) or -13(3x+4y-5) = 5(5x+12y-1)
14x-8y-60=0 or 94x+112-70=0

OOOOoooOOO I forgot absolute values >.<" At least I know now =]

He is accelerated 2-3 years early.

wow your just a family of mathletes then

 

[Timothy.Siu]

wow your just a family of mathletes then

lol i like that term, mathletes

 

[Aplus]

wow your just a family of mathletes then

Everyone in Asia accelerates that fast though.

To be honest, yr 7-9 are too easy that the contents can be learnt in a semester if learnt properly and if the contents are properly compressed.

I am just teaching my brother the way I learnt 9-11 maths in a year.
