is there anybody who can ans my question.. ????:(

Since y=p is a straight line, and a horizontal one,
Y co-ordinate has to be P.

X co ordinate can be found by substituting y=p into the equation.
hence, 4p=3x+15
x = (4p-15)/3
y = p

Is this correct?

If learning is difficult for you, just simply derive them.
Draw a graph and mark (1,0) on x-axis.
Then mark (0,1) on y-axis.
If, for example, you want a matrix transformation for reflection in x-axis, so (1,0) remains same as it is already on the x-axis and (0,1) becomes (0,-1) after reflection.
So the matrix transformation becoms [1/0 0/-1].
I wonder if you can understand like this but that's all I could explain here.
Solve past papers/
bro, id e so so so obliged if u could xplain tht matrix thng in paint and upload a screenshot :( would b quite a bit of hassle for u but please....

O Levels or A Levels?
EDIT: Just read the title so O Levels only. Removed the infinity term formulae.

A+(n-1)d

A= First Term
n= Nth term
d= Common difference.

This is only true for Arithmetic Progressions.

I don't think Geometric Progressions were a part of O Level Math. I'll check and get back to you on that.

Nonetheless, for G.P
A(1-R^n)/(1-r)

A= First term
R= Ratio b/w them
N= Nth term/Number of terms.
Thanks! I'll try some questions

yes but when we are dividing like that, 1 will not be divisible so a decimal will be placed but how will we know that an extra zero has to be written down before putting the decimal?
Try some complex figures like 753/4 and this method will be good enough !
These simple calculations can be verified so you don't need to worry about them !
