is that right?

I think so... u used similarity or what?

Nope you could get values by putting the function = 3x + 1 and rearranging to bring all the terms to the left side and then simplifying. A was -5, b was -1, c was 12.

Thats exactly what i was wondering.... but the question said USE YOUR GRAPH not algebra

How is it 55/56? They said she then picked a third sweet, find probability that she does not pick Lemon in any of the three so it could be either O,S,O or S,O,O or O,O,S. That gives 3/28.

:'( :'( :'( :'(

Nopes i used trigonometry

what was that fuel question? 600/x question
what were the answers?

 

[Saad the Paki]

Which question was this?

so am i right now?? please tell me i am right AnonymousX9

Same here...

I subtracted 15-8=7 of the trapezium and then used SOH

 

[Saad the Paki]

Yup

the value for the litres was 13.5 right?!

 

[misscute406]

yes yes!!

 

[Saad the Paki]

A

I subtracted 15-8=7 of the trapezium and then used SOH

oh wow.. same method here too!

 

[iThink LARGE]

-80 and 100

I got the same

 

[iThink LARGE]

A

oh wow.. same method here too!

high5 what were the ratios of the masses?

 

[Saad the Paki]

high5 what were the ratios of the masses?

I cant remember... :/

which paper was better? paper2 or paper4?

 

[NOneed2speedd]

bearing was?? B from A??

I don't remember but first u had to find angle A using sine rule and then subtract it from A to C

 

[Saad the Paki]

which paper was better? paper2 or paper4?

Definitely Paper2
