Question

Find the constant of variation k for the inverse variation. Then write an equation for the inverse variation. Y = 4.5 when x = 3

A) k = 1.5; y = 1.5/x
B) k = 13.5; xy – 13.5
C) k = 1.5; y = 1.5x
D) k = 13.5; 13.5y = x

Answer 1

okay so do you know what equation u have to use ??

Answer 2

hmm that is slope intercept form equation

Answer 3

\[\huge\color{blue}{{\rm y = }\rm \frac{ k }{ x }}\]
this is equation for inverse variation
u have to find k(constant of variation ) so replace y and x by the value that they gave you then solve for k

Answer 4

C

Answer 6

let me know if you didn't understand @Answers101

Answer 7

I don't understand @Nnesha

Answer 8

okay i gave u the equation right
and u have y and x values u need to find k replace y by 4.5
and x by 3 then solve for k

Answer 9

I think the answer is either B or D because 13.5 divided by 3 is 4.5

Answer 10

what is k value ??

Answer 11

13.5

Answer 12

yes right now replace k by 13.5 in the equation that i gave u

Answer 13

Y = k/x So 4.5 = 13.5/3 right?

Answer 14

so which one ur answer ??

Answer 15

D ?

Answer 16

@Nnesha

Answer 17

look at ur answer choices there is mistake somewhere check it

Answer 18

B

Answer 19

nope i'm saying there is mistake somewhere look at again there is typo or error

Answer 20

On B I meant = instead of -

Answer 21

yess so its
is it right or not ??

Answer 22

Yes
