Rearranging the subject of the formula isnt too hard but can get very tricky depending on the numbers,stem and leaf and questionaires practically spoonfeed us marks.


Especially difficult when you have to factorise. Ikr, they're great. For harder questions maybe like vectors, simultaneous equations (hope not), circle theorems and surds

So am i but even I sometimes rush into my answers without thinking.


same I need to be more focused

I think when they say"prove this is a straight line using vectors" might be the toughest question we will get tommorow

OooOoh the tension hahah :wink:


haha - didnt mean for it to sound that bad (just realised - whoops!)

there are other ways of doing the question but the one in the solutions is easiest (i initially tried the method 'mahrez' used but got in a pickle!)
What is the difference between alternate angles, supplementary angles and corrosponding angles?
Original post by Mahrez
2.5x 3=7.5
0.25mx0.2=0.5
7.5/0.05=150
150/20=7.5
8X8.50=68


I corrected it pink lemondade

Hah no it's ok your confidence just made me laugh :mmm: I haven't even looked at the question lol!! Good luck (: what you revising now?

do you know or are you testing people? :smile:

No i do but dont in a way so i want like some help

alternate angles are your z angles so if you look at the parallel lines try and see if there's a z and the angles on the inside of the z are going to be equal.
corresponding are the f angles so the again look for an f shape this time using the parallel lines and the angles on the inside will be the same
i don't know what you mean by supplementary? is that when they add to 180? if yes then angles on a straight line add to 180 degrees
erm my explanation is a bit hard to understand lol but if you type in z angles and f angles on google images hopefully it should make more sense
hope that helps :smile:
hi
do we get tracing paper in the maths exam?
Is on maths website down for you guys?

Supplementary angles just add up to 180, so angles on a straight line and co-internior angles are supplementary.

Ok sure, try to remember it as VOICA
VO = vertically opposite angles are the same
I = internal angles (supplementary) angles add up to 180 degrees
C = corresponding angles are the same. These are the f angles
A = Alternate angles are the same. These are the z angles.

Hope this helps

yes I think thats right and thank you very much

hi
do we get tracing paper in the maths exam?


yep we should do
(x-2)- (2/(x+1))=1 find X

no if cross multiply (x^2+x-4)/2x+2=1
2x+2=x^2+x-4
0=x^2+x-4-2x-2
=x^2-x-6
=(x-3)(x+2)
x=3 or x=-2

Nope, i think you're wrong, I double checked.
