Q14)a) x= 130 (180 - 50)
b) x= 230 and x= 310 ( 180 +50 and 360 - 50 )
Q15) 3* (4x-3/8) - 2*(3x-4/12)
12x-9-6x-8/24 = 6x-17/24
Q20) g inverse = multiply the bracket with a (-) so it can turn positive [x-3/-3]
( x +3/3 )
18+3/3 = 7 ??? hope thats correct
Q21) w = 90
x = 20
y = 40 ( 180 - (20+20) = 140 [180 - 140 = 40 ] angles on a st. lne add up to 180 )
z = 130 ( 180 - (90+40) = 50 [ 180 - 50 = 130 ] opposite angles in a quadrilateral add up to 180 )
Q23) u have to look at the graph ... there will be a point where y=-x thats wat they want u to find and the answer is -.6 draw the curve and u will see that .6 on y axis is equals to -.6 on the x axis .... so the point is (-.6,.6) ... the answer is x = .6 :D
oh for Ques 20(b) its:
y=3-3x
now make y the subject
therefore its: x=(y-3)/-3
then substitute 18 in to y
so its:
x=(18-3)/-3
x=(15)/-3
x=-5
solved the ques!! ;)
hope you understood!!!
IGCSE (CIE) Mathematics Paper 2 May/June 2001
(i have attached the paper)
Page 6, Question 14, Part (b) < -- it seems ill never get these graphs !!Page 7, Question 15(Done)
Page 8, Question 19, Part (b) < -- what are prime factors ??Page 10, Question 21, Angle z(Done)
Page 12, Question 23, Part (c), Section (ii) < -- what do they actually want ??
Total Questions Left: 4
I really hope i get the same help i got on my last post, help me guys ???
prime factors r numbers which can only be divided by 1 or itself. eg. 1, 2, 3, 5, ect
therefore product of prime factors for 99999 is = 3*3*11*101
cos all these numbers cannot b gotten by dividing by other numbers except 1 or itself
did u get it?
please here too

Thanks a lot
:D lol
ppl got used to that when u post anything, it will be old past papers LOL :D
u mean part C (ii)?
i this question the rule of
Y=Y applies
F(x)=2x
y=-x
so, 2x=-x
so the answer is the intersection of the 2 lines.....
i guess X will finally be -0.5 (just imagined the line), draw y=-x and check the intersection
a line needs 2 points.......but take 3 to be sure of it
take,
Y=0 >> (0)=-X >> X=0
Y=1 >> (1)=-X >> X= -1
Y=-1 >> (-1)=-X >> X=1
(0,0) (1,-1) (-1,1)
now plot the line and find the intersection
i didnt use Y=2 because on the grid the last point is x=-1.......use points that are available :D
ohh By the way.....any other questions we will be here for ya (me, twilight, astarmathsandphysics, amber and aishath)
gd luck dude! :) :D
Qboy can you post the ms for this? its not in freeexampapers! thanx!
now i have doubts in this paper!
Q11.(ii)
Why is it 0.255 shouldn't it be 0.254?
Q7. Isn't it 1:8? The mark scheme says 8:1!
