  what does the gradient mean?
  tt 1 i anyhow answer lol. i wrote it meant the object was falling down towards the ground at 11m/s. but looking back now there seems to be no other representation for the magnitude...no si unit for it zzz..gradient = m/m

  gradient should be -10
  
  gradient should be the gravity. i get -12, dunno will get penalised boh.
  
  haish i got a feeling i never do good for my o levels.

  perfect gradient is -11. do dy/dx and u'll noe.

  2(a) (i) Simplify n^2 -(n+a)(n-a).
  (ii) Hence evaluate 326541829^2 -326541833 x 326541825.
  
  (b)Solve the simultaneous equations
  2x=y+6,
  6x-2y=13.
  
  (c)It is given that y= t^2 -2.
  (i)Find y when t=-3.
  (ii)Express t in terms of y.
  
  (d) Express as a single fraction in its simplest form
  
  5/3x -1/6x

  eh. method marks hor...
  
  if for e.g... that quest on "percentage reduce"....my values are wrong...but my method is correct (value difference/initial value *100%)...So will i be awarded the method mark?...Let's say only 1 mk is deducted for accuracy?
  
  And also....the one on the GST....i took it as 100%...So my ans is wrong.. But method is there. Any method mark?
