Question

.

Answer 1

@kx2bay
hey i have one more question and i don't think anyone would understand it but u

Answer 2

Two different relationships are shown below.

Relationship 1: y = 8x

Relationship 2:

a) Identify each relationship as direct or inverse variation.
b) Calculate the constant of each relationship and explain how you arrived at your answer.

Answer 3

hey housekill, somehow the image shows only the points from a curve, are u sure this is the right image for this question?

Answer 4

yea thats the one it shows in the question

Answer 5

why is it not usable liek does it not make sense or something ?

Answer 6

so the image is for relationship 2 right?

Answer 7

yea i need to know what relationship 2 is and that image is in the question so i think so

Answer 8

that looks like a curve, let me think what the formula is, but I can help u answer the first question

Answer 9

what the one that says identify each relation ship as a direct variation ?

Answer 10

in the first relationship y = 8x, u can see that as the value of x increases so does the value of y so this is called Direct Variation

Answer 11

for the second relationship, if you notice as X moves to the right, i.e. increases, Y moves down, i.e. decreases, so this is Inverse variation, ok?

Answer 12

is that for the first one ofr second one ?

Answer 13

ok, I got the equation for the second relationship, it is

y = 8 / x

and if u use the points on the graph and substitute each X with a value u will get the corresponding Y

Answer 14

the answer to ur above Q is - for the first one

Answer 15

but the first relationship is y=8x are they sup post to be that alike

Answer 16

now about calculating the constant, am not sure if they are referring to the 8 or the Y intercept, so please ask someone else to verify that, may be @ganeshie8 can help???

Answer 17

It says the calculate the constant of each relationship so like i think which one stays the same

Answer 18

so if refashionship 2 is y = 8 / x i think 8 is the constant right ?

Answer 19

I know I also think so, it is 8 but please confirm also with some one else

Answer 20

@ganeshie8 can u help please?

Answer 21

okay @Miracrown can u tell us if 8 is the constant of y = 8x
and y = 8 / x

Answer 22

@ganeshie8 can u verify that

Answer 23

oh yes @Miracrown is good

Answer 24

Relationship 1: y = 8x

Relationship 2: y = 8/x

Answer 25

yea so the constant is 8 right

Answer 26

constant of variation for first relationship is 8
const of variation for second relationship is 8

Answer 27

compare them wid standard equations :
\(y = kx\)

\(y = \dfrac{k}{x}\)

Answer 28

okay thank you we just needed someone to verify that for us

Answer 29

Answer 30

@Miracrown nvm we got the answer

Answer 31

That's great! :-]

Answer 32

@kx2bay okay how are they different from each other i know there similar because they have the same constant

Answer 33

@kx2bay u there ??

Answer 34

@ganeshie8 can u tell me how y=8x is different from y=8/x
