great game.

you know, you can use e-mails,but it's going to be slower because of the fact that more people will see PMs rather than e-mails.

hi zee-f

number 4,5,6 are correct.8 is (-2,-4).9 is correct.10 is incorrect,it should be (13/5,7/5).as for 14 y=2.16,17 and 18 are also correct.

hi zee-f

your answer for 1 and 2 is correct.and if i calculated it correctly it should be E.
first try to set an equation for first part of the text.
then set one for the second part.
then solve like a system of equations.
if you get stuck somewhere just ask.

aah.ok think i get it.

could you also make a topic on integrals?it would be nice to practice working on them.
