guys (A U B)'' aur (A intersection B) mein koi difference hai ??

Yes, a big difference. In (AUB)' you shade every other part except A and B while in (A intersection B) you only shade the common!

No specific way, trial and error i should say !
btw n=n-5 is not an expression

want to ask one thing. in circle questions where angle is to be found which is usually about 1 mark should we write down the answer straight away or write too the property which we are applying?

write the property u r applying! it may not be of marks but it may help you in further parts of the question

(A U B)' = A' intersection B'

If you haven't memorized it then draw a imaginary triangle and put its coordinates in a matrix form. Multiply it with the Matrix given and draw the resultant coordinates. You'll come to know which transformation it is!

only if you are left with time

De morgan's law: (A U B)' = A' ∩ B'
So of course there is a difference!

Q1 B

 

[beeloooo]

Given that
f–1(x) = cx + d, find the values of c and d.

find f inverse ....it will come in the form cx + d !!! and the value with x will be c and the other lone value d !!

4 times as many people owned a car only as owned a bicycle only it should mean like 4p=x isn't it? but the markscehme says opposite
