i will try my best :)

Thank you! Give me a few seconds.

ok

1st Q: http://prntscr.com/7a1nki

If you don't know it, it's fine, we can move on if you'd like :)

I'm in algebra 2 as of now and I'm not sure of the answer lol

Okay! No problem. (I'm in Algebra 1) Let me get out the next Q.

http://prntscr.com/7a1pxw

It would be A. you want an explanation?

Yes, please :)

ok so the shaded part of the graph would all be correct answers

and A is the only ordered pairs within the shaded part

Oh okay, so by trial and error, one can get the correct answer easily. Thank you!

np

Q.3: http://prntscr.com/7a1r4w Are they asking for the rate of change?

I don't think so

im pretty sure its C.

Why is that?

because when i plugged in the numbers into the equation they equaled eachother

5 is plugged into h(5) =

and 0 is plugged into x

yep :)

http://prntscr.com/7a1ssa I was thinking it's either the peak or the left part

(Those are the only parts that make the function non-linear)

So it's either A or B

But then C also describes the peak

huh

or no sorry not C

Precisely... but they're asking for an interval, so it can't be C

Ya its a or b im not sure which one

ya i was just about to say that as well

i would go with A

Okay! http://prntscr.com/7a1uuj (Let me know when you're sick of answering my Q's) :)

so 24 = x/3

then you would do inverse operations

and get x = 72

Okay, like cross-multiplication. So it would be 24 * 3 and x * 1?

ya that would work too

72/x?

it would be 24 * 3 = x * 1

So 72 = x! Meaning answer is D?

you forgot the equal sign

yep

What is the pattern of this sequence? http://prntscr.com/7a1wqe

Do you have any ideas what the pattern might be?

yeah im not sure on this one sorry:(

No problem! :) Next one: http://prntscr.com/7a1z2r

I think it's A.

Yes it is :)

http://prntscr.com/7a1zt7 Disregard the answer I chose, it was by accident.

Yep and might I say u seem really smart btw you type lol

so your in like AP algebra 1 im guessing?

There isn't an AP Alg 1.. is there? I'm in honors

there is in some schools but I think its A but im not sure

I understand :)

Next question? or are we still on this one?

I believe that the answer to the one I just asked is either A or B

Oh it's above :)

And B would eventually exceed 24,000 if im not mistaken

Since the value of the car is a decreasing exponential function, I agree with your points.

I think it is C. actually

But wouldn't the 'y' represent range instead of domain?

thats also what i was thinking as well but its the only one that makes sense i think

or no cause its also greater than or equal to

either there's a mistake with the question or we are missing something lol

oh ok then that must be it

http://prntscr.com/7a2622 (Again disregard the answer)

Ya its C

since its asking for the Y values (or range values)

lol

:P

http://prntscr.com/7a2796
http://prntscr.com/7a27c5
(It wouldn't fit into my screen)

Right. It's linear.

yep

Are you still willing to help? I know that your time is precious.

Yes I am still willing to help i just do my homework while helping others :)

Thank you for that and no problem :)

With that said.. http://prntscr.com/7a28mg

It is A.

Because the x-intercept is when y = 0, right?

And vice versa for the y-intercept.

yes thats correct

Or its B sorry

because when you set y equal to zero then that goes away leaving you with x = 12

because -6(0) = 0

Right. Sorry I didn't see that error either.

http://prntscr.com/7a2afg

I'm not sure what zero of this function means?

It means when y is set to zero

Also known as the x-intercept

oh ok

So its D then right?

well the equation f(x) = 1/2x -4

When x = 0 the y is -4

and if y = 0 then x = 8

Horrible homework makers

but im pretty sure its asking for the x-intercept

http://prntscr.com/7a2e21 You're right

They're asking for the x-intercept. So it would be D.

Ya ok

http://prntscr.com/7a2ekm

4 would work

Since it's absolute value, the answer would ultimately be positive,

Yeah

but 20/3 would not since it would make a decimal

You're right.. again! It can't be the other options either

and the other numbers are way to big

so theres no answer..... lmao

Another mistake.. I'm totally going to contact my teacher about this

yeah you definitely should :P

http://prntscr.com/7a2ggl

I have very few left

I could graph this one OR calculate its vertex and ultimately maximum point.

Yeah, we won't always have access to graphing calculators on the exam.

because your not allowed or you just dont have one?

So vertex formula is: x = b/2a, right?

Or maybe I mixed it up

its -b isnt it?

Right! -b/2a = x

b = 300 and a = 5

-(300)/2(5) = -300/10

= -30

Hmm... answer choices don't match up

it would be 300/10 wouldnt it?

not negative

No it's negative because of the "-b"

for the x side

and its also a negative 5 so

it would end up being 30 = 30

if im not mistaken

yes lol

and your very smart :P

honestly

http://prntscr.com/7a2ley I don't think so.. math is one of my weaker subjects haha

The formula for exponential increase is: f(x) = Initial Value(Rate)^x

ok so

But I also recall a (1 + r) rate to an exponential function

the r is if there is an interest rate

or no disregard that statement lol

Ah, okay. So what are your thoughts?

I think its C and ill explain

Okay

sorry if i didnt explain that well enough lol

oh your completely right since A (the initial population) is already in the equation.

my bad :P

So yes its A

Yes! I outsmarted the wise one

:) Jk jk

haha

all good

trust me its not too hard to outsmart me at times :P

http://prntscr.com/7a2r8m I doubt it!

is D. y = 88x? or is it just y - 88x? lol

D. is y = 88x

ok

I think what they're doing is the simplified version of 40/880

So It would most likely be B

Yes that is correct

i wouldn't to try and outsmart you if math is your weaker subject :P

|dw:1432751159345:dw|

It's A

you mean divided by 20 right?

No, by 2… it's kinda how I simplify fractions in my head

I cancelled out the zeroes

oh yes i understand ok lol see i told you its not to hard to outsmart me :P

|dw:1432751466669:dw|

Same answer lol

for sake of me learning now lol why is the 40 the numerator and not the 880?

you dont have to explain if you dont want to :P

Oh pretend that it's not a fraction.. I just divided both numerator and denominator by 40.

no i understand that but for the equation why is it 40/880 and not 880/40

ya

im not sure which way it should be set up

In other words, it's y/x… so now I'm truly split between this

I believe that the relationship refers to slope.

So im pretty sure it is B now lol

does that make sense?

Definitely. (See, you outsmarted me again)

http://prntscr.com/7a2wi6

hahaha that seemed harder than it should have been

Another sequence problem ^^

right lol

i would guess B

I would guess either C or D because B would be the 6th value.. not the 8th

but im not exactly sure what the pattern is

so u think the fractions are multiplying by 2?

|dw:1432752458487:dw|

The last three have a pattern and the first two have a separate pattern

i saw that as well

so D then correct?

I think D is the answer

ya and the numerator is multiplying by 2

Brb for 5 mins

ok

just tag me in the chat when you're back :)

I have 5 or 6 Q's left if you're up for it

im up for it :)

Thank you! http://prntscr.com/7a3hj7

Please disregard the answer I chose.. it's a random guess as I didn't look at the Q

It's C right?

Ya it's C

Let me check

Yup! It's C.

http://prntscr.com/7a3kpt I put the #'s in order

School A: 1300, 1350, 1350, 1370, 1400
School B: 1300, 1350, 1375, 1400, 1410

C is correct for the first part

I think #45 and #46 are separate Q's and aren't two part Q's

ok i thought so as well

Is #46 D?

I'm not sure

Wait no it says least likely to be a normal distribution, so it's either A or B

It would be B then right?

How old are you just curious?

I'm 12 but I take advanced class and skipped two grades

classes*

:0

im embarrassed now lol

Why? No need to be but how old are you?

I'm 16

Most of my friends are 15+ haha

and your just as smart if not smarter than i am lol

true true but back to the Q im not sure what it is :(

It's fine! I put in A. http://prntscr.com/7a3qw7 Last question and you're free of me! :)

It would be D :)

Yup! Just checked. Thank you so, so much.

np ;)

Just tag or message me if im on if you want any help

ok you too :)
