Could the answer to the final question possibly be x= -1.25 and y= 3.25 ?

For the bank question i worked out 2000(1.04) and 2000(1.01) and then added them together (for the international bank and then the same w/ different values for the friendly bank) is this correct?

I got £6000 for the scatter graph estimation one - is this close enough to get the marks or were they looking for £6200 specifically?

On scatter graph questions there are always a range of acceptable answers.

for the final question i did everything right, i made y the subject of the formula then plugged it in to the first equation, then made it equal zero, then i did the quadratic formula , i did everything completely right but i made an error on one of the numbers when i plugged it into the calculator which left me with different final values than i should of got (could't believe it when i got home - i was furious). Will i still get 4/6 of the marks? , PLEASE ANSWER, cheers

Hi, what was the trial and improvement question?

Was it x^3 + 2x = 100?

110 not 100.

It can vary depending on the position of your line of best fit.

Mr M, I have a couple of questions. Firstly, What was the first question to do with surface area with the answer 40.5?
Secondly, For the answer with upper and lower bounds i put my answers to three decimal places with the longer answers written out in the working, will I get full marks?
Thirdly, for the inverse proportion question, what was the question and how do you do it?
Thank you so much for your time.

thanks

if i put the correct answers but used trial and error on the last question, could i still get full marks

i.e. i put 2.87/-0.87 and vice versa, but no simultaneous equations working out, could i still get 6 marks? cheers

I've answered this already. Yes that will be ok.

Mr M u know for question 9, I did angles in a triangle add up to 180 and then I got the 55 but then I used angles on a straight line to work out the angle like 125. I then used allied angles to work out the required 55. Long winded I know , but would I get the marks??

what do you reckon will be will be the grade boundaries for an A?

Were these papers harder than last year?

For the last question would I get any marks for this? This is how my teacher taught me... But I'm really confused now!

x^2 + y^2 = 9 .....(1)
x + y = 2 .....(2)
From (2) we get
y = 2 - x
Substitute this value for y into equation (1) to get...
x^2 + (2 - x)^2 = 9
x^2 + 4 + 4x + x^2 = 9 [ multiply out the bracket]
2x^2 + 4x - 5 = 0 [ gather terms on the left hand side]
This is a quadratic and it factorises to give
(2x + 1)(x - 5) = 0
Either
2x + 1 = 0
x = - 1/2 = - 0.5
or
x - 5 = 0
x = 5
- 0.5 + y = 2
y = 2.5
5 + y = 2
y = - 3
x = - 0.5, y = 2.5
x = 5, y = -3

I believe it was -4x, when you expand (2-x)^2 , Although your method looks right.
