tell me why if it's wrong?

its not wrong.

 

[starryblue]

good luck every1! hopefully, we'll all get band 6's without studying! lol...impossible for me

 

[Some Vunt]

I don't get why they would make a school certificate exam if they are going to be testing you on year 8 work?

I don't get it either but that's what they do. :/
Except in my year the last question had some sort of geometric series shit that I had no idea about (piss easy, but I had never seen anything remotely similar before the exam)

um, get 85%+ correct ?
are you that dense ?

It's actually probably less than that. Haha

no, to get band 6, its 90+
i got bloody 85%!
5 more man!
So devostated!
but it was okay i guess.
did accelereated maths btw.
(that means i still gota do school cert this year for other subjects) <---

Get out.
It's obviously less than 90% raw.
I didn't answer several questions and I got the whole last page wrong and I got 96. Hahaha

My goal is 99. Is it possible?

My goal is 99. Is it possible?

Without a doubt, yes, if you have studied.

Btw which subjects?

2 x 4
= 8 units squared

 

[twinklegal19]

B(?,3)

sub y=3 into y=x+2
3=x+1
x=2
therefore B(2,3)

C(2,?)
sub x=2 into y=9-x
y=9-2
y=7
therefore C(2,7)

Area = 2 x (7-3)
= 8 units squared

Well by studied, I have been practicing math everyday for about an hour for the past year. I have done well in the practice test I have done and I feel really confident. I am only doing math as the subject because I'm just in year 9 and accelerated.

every day for an hour..? wow you're dedicated! I think about studying and then I turn my computer on and before I know it, it's already 11pm and I've spend like 5hrs playing video games ._.

haha, same! except instead of playing video games, I just surf the net... for hours

Is it possible to somehow obtain a copy of the SC paper after the exam has been completed? I was thinking about getting one and redoing the test at home and posting the answers on here and for my friends, to see how everyone went.

..+explanation..
lol

lol

1 hour, 10 to 2 is 4 hours, whilst 5 hours had gone by. Hence was turned off for 1 hour.

Solve:

(x+2)^2 > -x

 

[zombies]

(x+2)^2 > -x

(x + 2)^2 > -x
x^2 + 4x + 4 > -x
x^2 + 5x + 4 > 0
(x + 4)(x+1) > 0

x < -4 , x < -1

so x < -4 ?
I'm not really that sure tbh lol

 

[lath]

(x+2)^2 > -x

x < -4 and x > -1

Not to discourage you but that is quite a lot. Don't you find it repetitive as I remember when i was in year 9 there was no need to do any more than you did in class. It was all just too much the same. I advise you challenge yourself with questions you are not familiar with.

 

[RealiseNothing]

x < -4 and x > -1

Yer it's this

That would be a harder 5.3 question I think, no chance it would come up in the SC exam this Tuesday.

 

[RealiseNothing]

(x + 2)^2 > -x
x^2 + 4x + 4 > -x
x^2 + 5x + 4 > 0
(x + 4)(x+1) > 0

x < -4 , x < -1

so x < -4 ?
I'm not really that sure tbh lol

Just plug in a number between -4 and -1, if it suits the equation, then it is -4 < x < -1

If it doesn't suit the equation it has to be x < -4 and x > -1

So say x=-2, then -2^2 - 10 + 4 > 0

Which says 4-10+4 > 0, then -2 > 0

So it's false and x must be less than -4 but also can be greater than -1.

Why wouldn't this style of questions come up?
