Hi are some of your answers wrong in answers part to paper c, non calculator. In particular Q:2,5,8(a)(b). My maths may be wrong on 5 but am not sure however I have put Q 2 into a calculator and it gave me the answer I had instead of in the answer scheme. I also can not see how 8(a) is 2 and not 1/2 which would also make b wrong. I have practiced these questions over and over and can’t seem to make the answer scheme fit?
Sorry buddy! These are not my answers but they are correct!
Q2 you must follow BODMAS and do addition in bracket first. This gives 7/4 + 3/8 which is 14/8 + 3/8 = 17/8. Multiply by 2/7 to get 17/28.
Q5 Factorises to (7 – x)(1 + x) = 0
Q8(a) Using your gradient formula (the right way round!!) gives (3-(-7))/(4-(-1)) which is 10/5 = 2. Then answer to (b) follows.
Good luck today!!
