    you just know that x = 8 so plug in x = 8 into the equation x+ 2y = 0 so then 2y + 8 = 0 => 2y = -8 then solve for y

      JAPBOYGT, DUH back atcha. Why is it OK for you to say x<>8 above and then say x=8 here, telling DicipleofMath (dom) he's a dumb fuck for saying x=8? x=8. You're the dumb jerk of a fuck. dom was just being nice enough to give sheliad a heads up on how to solve.

    3x8=24
    x+2-4=0
    y= -4 haha! :)

  3x=24 divide both sides by 3 to find the value of x. Then substitute the value of x for x in the second problem and solve for y.

  Slide 3 is wrong.

  Area of triangle = (1/2)bc*sinA

  Slide 1 layout is really bad
  He is trying to say
  (Sin A)/a = (Sin B)/b = (Sin C)/c
