1. And since it is nearly always the extreme points of the regions, I tried all three. Two were obviously useless (y=0...), and the top one gave 14. I did not take it any further than this. There are ways it can be checked, but I am very, very lazy...
2. oh yeh did the top oen two but ended up with 18 dont no how i managed that but aybe marks for subsitution. what was the line again 2x and 3y equals 18?
3. (Original post by clowes)
What was question 10 and how did it involve simultaneous equations.. I can't remember.
"Find the coordinates of the points of intersection of the line y = 5 - 2x with the curve y = x^2 - 4x - 11, giving your answers correct to 2 decimal places."

I forgot to find the y coordinates.
