Edexcel IGCSE Mathematics 4MA0 4H - 4th June 2015

What did people get for the last question??? I got x=4 y=2 or x=-4 y=6 but I'd don't think you were supposed to get two different answers ?? Because I got my answers from putting the question into the brackets (5x-20)(x-4)

the co-ordinates i got (0,5) (-4,37) what did people get for the vectors question? did you add them?

oh i got the wrong answer do you remeber what you differentiated?

For the hexagon quesstions did every get that It's (n-2) x 180 which gives 720. Then minus the angles you're given then divide by two to give 142???

7 on the top and then -4 beneath or something like that i can't remeber exactly but you had to reverse DC

It was (0,5)

Yeah that's right

Yeah you're supposed to add them. The answer was 7 on the top and -4 on the bottom.

It was only one answer, x=4 and y=2. When you factorise the quadratic you should have got (x-4)(x-4)

How did everyone find itttttt

Really happy that 4H was much easier than 3H! The balance has been restored now. Grade boundaries won't change that much. I'm guessing A* is 80 ish. Maybe 79 but really it should be quite high I felt.
(That's my boundary prediction for both papers by the way.)

Same here, definitely a bit more confident about an A* but we will see!! I think they will be high 70s too so let's hope they go in our favour 🙏

also how many marks would you lose if you put -2 and -4 along with 4 and 2

one because that's wrong

-2 is not equal to 10 - - 4

(5x-20) = 0

x=4

(x-4) = 0

x= 4

so....ur wrong its only one answer whih is x = 4, y = 2

What are y'all predicting for grade boundaries?
I'd say 85 A*. 72 A. 60 B. 54. C.
I know these are quite high but i thought the paper was really good and (judging from the unofficial mark scheme) I got 87 :smile:
