Question

medal(:

Answer 1

For each function, y varies directly with x. Find each constant of variation. Then find the value of y when x= -0.3.
13. y= 2/3 when x= 0.2

Answer 2

@Nnesha

Answer 3

\[y=kx\]and in this case \[\frac{2}{3}=0.2k\], so find \[k\](the constant of variation)then substitute it in the first equation i wrote to find \[y\]when \[x=-0.3\]

Answer 4

oh okay so I would do 2/3=0.2(-0.3)?

Answer 5

can you help me with math questions please? :)
@pkjag

Answer 6

No, you have to find a different \[y\], the first one has been given so that you can find \[k\]. First solve for \[k\] for now

Answer 7

so instead of using the -0.3 I put in the 0.2 and solve?

Answer 8

yes, just \[k\]for now

Answer 9

okay im sorry im still a little confused /: can you give me step by step? Like the equation I start with and so on just so I know how to work other problems like this

Answer 10

@Nnesha im confused do you think you could help me? /: its saying x=-0.3 but then in my question its giving me x=0.2

Answer 11

we are working on the 2nd equation from my first reply

Answer 12

just find\[k\] by dividing \[\frac{2}{3}\]with \[0.2\]

Answer 13

whats the question ???

Answer 14

0.13?

Answer 15

@Nnesha For each function, y varies directly with x. Find each constant of variation. Then find the value of y when x= -0.3.
13. y= 2/3 when x= 0.2

Answer 16

see what throws me off is it says x=-0.3 and then the question says x=0.2? and no it doesn't have a table or anything that's why im confused /:

Answer 17

2/3 divide by 0.2 isn't 0.13?

Answer 18

@pkjag it is or isn't 0.13? cus when I did 2/3*0.2 that's what I got?

Answer 19

it isn't do 2/0.6

Answer 20

@pkjag I got 3.33? but how did you get 2/0.6?

Answer 21

@nnesha you shouldn't be multiplying

Answer 22

@Nnesha no I don't have multiple choice answers /: and I did 2/3*0.2 and I got 0.13

Answer 23

yes now thats k the constant variation, use it to find y when x=-0.3

Answer 24

use y=kx

Answer 25

okay so y=3.33*-0.3?

Answer 26

yes, but i don't understand part of your question: 'when x= -0.3. 13. y= 2/3 when x= 0.2' whats the 13?

Answer 27

13 is just the question like 13. y= 2/3 when x=0.2 like this question that I may also need help with 15. y=4 when x=-3

Answer 28

this:For each function, y varies directly with x. Find each constant of variation. Then find the value of y when x= -0.3.

Is just saying what we need to follow for the questions I think .-. that's why im confused

Answer 29

for all other questions like 13. start with finding the k, since you already have x and y, then use that k like you did in : 'okay so y=3.33*-0.3?'

Answer 30

this is what i got so far
