help pleasee A segment with endpoints A (3, 4) and C (5, 11) is partitioned by a point B such that AB and BC form a 2:3 ratio. Find B. (3.8, 6.8) (3.9, 4.8) (4.2, 5.6) (4.3, 5.9)

    2 equation, 2unknows The distance between the points is known, let it be d So the distance A and B =2d/3...1 The distance BC =d/3 By these two eqautions, both unknowns(x,y coordinates) can be found

    I'm not sure if what you're is okay, but surely the distance will device to 3 parts, not 5. That is, one third and two thirds

    hmm I'm thinking of a different way but I get what you mean.. I'll try your method and see if I'll get the same thing.

    oops sorry, I'm talking to ahmad.. and no, it shouldn't be 2/5. distance of AB= 2/3 and BC= 1/3

    no, because it is not exactly referring to the actual distance. It only shows the scale on how far is A to B and C to B

    oops sorry I lost my connection So we'll do the x-coordinate first, bx. (bx-ax) : (cx - bx ) = 2 : 3 (bx - 3): ( 5 - bx) = 2:3 it will be 3(bx-3) = 2(5-bx) 3bx - 9 = 10 -2 bx 5 bx = 19 bx = 19/5 Now, you do the same thing for by

    (by-ay) : (cy-by) = 1:3 (by-4) : (11-by) = 1:3 sorry im really bad at this .. need a little help on the next step.. ):

    (by-ay) : (cy-by) = 2:3 (by-4) : (11-by) = 2:3 I think the easiest way for you is turn the ratios into fraction |dw:1435173012809:dw|

    2(11-by) = 3(by-4) 22-2by = 3by -12 22+12 -2by-2by = 3by+2by -12+12 5by /5 = 34 /5 by = 6.8 :D
