You seem to have done very well on the exam, well done
Thanks! I did make one stupid mistake though, which was the k question with the cubic graph, even though I posted the working earlier, I know where I went wrong.

In the exam, I put 9 - 9 - 9 as - 27, even though it is - 9!

I literally left out so many questions - could not answer the isosceles triangle, I got to 3(3-3rt3) instead of 3(3-rt3) for the perimeter of the trapezium so gave up, wrote some random co-ordinates for the application of completing the square for the minimum point (could not remember what everything meant), kept getting different values for the simultaneous equations with the perpendicular fraction coordinates and bleh probably got everything else wrong too. What did everyone get for 'find the integer values bleh bleh -insert quadratic thing here- (or something like that)?' I got x is less than or equal to 12 but I have a feeling it's 8 less than or equal to x less that or equal to 12... (there goes my chance of a decent grade)
I don't think it can be equal to 8 or 12 because it's and inequality that says it has to be less than 0. It said write down the integers so I think it would be 9,10 and 11 but I left it as 8<X<12 as the answer: would is still get the marks?
3. me too

2x+48 and 3x

i did the same thing but i put -18 ((

i thought it asked state the range?

It's not going to affect your overall grade that much anyway, I wouldn't worry x

QUESTION=X^4+81
Simplify=(x^2+9)(x^2-9)
Simplify-further-blah
Rt X^4 = X^2
Rt 81 = 9
Difference of two sqaures = (x+3)(x-3)

really...I got just 9

-80
Yeah it was definitely -80 because it said y<0 and y could either be -1/5 or 1/5 so you had to use -1/5 which is less than 0 and do 16 divided by -1/5 which is the same as 16 x -5 which gave -80 🙌🏽

Oh sorry, I meant k - 9 = 0, and k - 27 = 0, so I ended up with 27, even though it was actually 9
12. (Original post by Romy06)

The answer for k is 9 but he is saying that 9 - 9 - 9 = -9 so to make it equal to 0 k has to be 9.

Annoying, isn't it?

That's a good point actually, but I think most people, including me and you, put 8 < x < 12. I think that should be enough though.

Cos(theta symbol)= -5/6

X=121 for the one that was like (3-rootx)^1/3 - 2

(X-5)^3= x^3 - 15x^2 + 75x - 125

Completing the square: (X+3)^2 - 7
Minimum value thing: (-3,-7)

For proving the perimeter thing, inthink you had to show it was 3(3+root3) by doing 3+3+3+6/root3+3/root3 then it made 9+9/root 3 in which you had to rationalise the 9/root3 to get 9root3/3 and then that gave altogether 9+3root3 then you just had to put it in brackets?

dy/dx was like 3x^2 - 20x (correct me if I'm wrong I can't quite remember)

The X/Y thing was -80

There was one where an answer was 45 (maybe X=45)

Where you had to find p and m or something it was 8 and -1

Centre of the circle I can't remember but it was either the 2nd or 3rd option.

The difference between 2 squares was (X+3)(X-3)

There are more but I can't quite remember off the top of my head

yh it was x<-8 and x>8
17. (Original post by Examscanyounot)
I got -80 for that because it was 16/-0.4 which is the same as 16 x -5 which was -80
i got +80
18. (Original post by lily628)

yh it said state the range of integers
19. (Original post by 1jonam16)
yepp. Tbf i'm glad no one is complaining seeing as the test was harder than usual, which is nice!
U know for the x/y question, i got 80, would i lose a mark? and for the trig identity i didn't do negatives for both :/

Hey u know for the trig question i wrote 3/5, would i lose 1 mark, i showed my working..?
