Find the x value for point F such that DF and EF form a 1:3 ratio. 0.75 −1 2 −1.75
so you know distance formula will be involved? and you want one distance to be 3 times the other, right?
I'm guessing so! :) @myininaya
great can you set the equation then?
Okay, 2 minutes please
\[\sqrt{(2-(-3)^{2}+(4-(-3)^{2}}\]
Is this correct? @myininaya
ok we have this line |dw:1402446909617:dw| we want the distance from E to F be equal 3 times the distance from D to F You should have an equation here I just called F (x,y) since we don't know it yet and we are looking for that value x
yes I understand so far!
ok try making an equation from that sentence
I am not sure on how to do this which is why I asked for help..@myininaya
I'm asking you to translate "the distance from E to F" is "3 times the distance from D to F"
replace the word is with an equal sign replace the distance from E to F with the distance formula and the points entered from E and F and do the same thing from D to F (which is on the other side of equation because it is on the other side of the is)
