Question

Which relationship shows a quadratic variation?

Answer 1

3rd one? @misssunshinexxoxo

Answer 2

Is it right @Loser66 ?

Answer 3

nope

Answer 4

what? why?

Answer 5

show me your logic, why 3?

Answer 6

(x-1)*2?

Answer 7

Oh wait.. oops, that doesn't work with all of them..

Answer 8

Oh, so (x-1)^2

Answer 9

to me, it's 4 because y = x^2 +1

Answer 10

quadratic form: y =ax^2 +bx +c

Answer 11

Oh, that makes perfect sense! So its the 4th one for sure?

Answer 12

S/U/R/E

Answer 13

Which is the quadratic variation equation for the relationship?

y varies directly with x^2 and y = 48 when x = 2.

A. y = 4x^2
B. y = 12x^2
C. y = x^2 + 25
D. y = 4x

B?

Answer 14

S/U/R/E? O.o

Answer 15

Y/U/P

Answer 16

Ok... can you see if my answer for the top is correct or not? :)

Answer 17

What is the top?

Answer 18

This one: @Loser66

Answer 19

Again, Y/U/P

Answer 20

you are correct :)

Answer 21

ok, thanks :) can you help with a few more, just see if they are correct, @Loser66 ?

Answer 22

just post, stay here, no need to open a new one.

Answer 23

Ok, thanks :) give me a minute?

Answer 24

Which relationship shows an inverse variation?

Answer 25

3rd one?

Answer 26

2*12=24
4*6=24
6*4=24
8*3=24

all answers are 24

Answer 27

Y/U/P

Answer 28

Ok, thanks :) just 2 more! @Loser66

y varies inversely with x and y = 5 when x = 2.

Which is the inverse variation equation for the relationship?

A. y = x + 2
B. y = 2x
C. y = 1/2x
D. y = 10/x

D?

Answer 29

if c is not \(\dfrac{1}{2x}\) then you are correct.

Answer 30

Nope, its 1/2 then x

Answer 31

Then, Y/O/U A/R/E/ C/O/RR/E/CT

Answer 32

Ok :)

Which is a coordinate rule for the translation of f(x) to g(x)?

A. (x, y) → (x – 4, y + 5)
B. (x, y) → (x + 5, y – 4)
C. (x, y) → (x – 5, y + 4)
D. (x, y) → (x + 4, y – 5)

Answer 33

Umm.. would this be B?

Answer 34

redo

Answer 35

redo? you mean wrong?

Answer 36

aha, however, have to recheck your typing on the problem, Are you sure you typing is correct?

Answer 37

Yep, there all correct, I just rechecked

Answer 38

oh yea, your typing is ok, your choice is NOT ok

Answer 39

Ok.. then C?

Answer 40

hey, don't guess!! I am a strict mentor. I will ask for the logic. OK why B? or why C?

Answer 41

which grade are you?

Answer 42

No, I'm not guessing! Well.. B is x + 5, and that means going up, right? and then y - 4 goes left? ugh.. this is soo confusing

Answer 43

I'm in 9th

Answer 44

Hmm.. can you explain more?

Answer 45

I would say A..

Answer 46

oh, I confused , too. hahaha, I am sorry, a point dilation is different from a curve dilation.
I need time to review or need other's help

Answer 47

I am so sorry Lovely Anna

Answer 48

@Isaiah.Feynman Please, give us your hand

Answer 49

Oh, its ok :)

Answer 50

So...?

Answer 51

How come @Isaiah.Feynman isnt replying?

Answer 52

I think it's D
about @Isaiah.Feynman I think he is sleeping

Answer 53

Oh, can you explain?
Lol, your funny!

Answer 54

Its C.

Answer 55

It is? :/

Answer 56

Wait.. for which question?

Answer 58

Oh, ok, can you explain?

Answer 59

@Loser66 do you think its correct?

Answer 60

Ok.. but can you please hurry, I'm in a bit of a hurry for something important.. :( @Loser66

Answer 61

if you are on that hurry, take @Isaiah.Feynman answer, he is better than me in maths

Answer 62

I haven't studied abstract algebra yet! @Loser66

Answer 63

Oh, ok.. I'll wait a few minutes for your answer, is 5 min enough?

Answer 64

FINAL ANSWER C

Answer 65

@Isaiah.Feynman It's A because x -4 only, y +5

Answer 66

So.. which one is it?

Answer 67

A

Answer 68

100% sure?

Answer 69

99% only

Answer 70
