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

14 (a) Thanks !! the ans is correct ;D
(b) the m/s says the ans is 210 and 330 ??? im confused !!
15 Thanks for the help, By the way -9--8 = -1, so the ans = 6x-1/24 ;D
20 i dont think it is ??? the m/s says its -5 how did we get -5 !!
21 Thanks a lot !! the ans is correct ;) (Thanks for the tips)
23 is there a formula or something, cause the graph only goes to -1 ???
Thanks a lot for the help amber. i appreciate it !!! :)
Aishath:
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!!!
