Question

Identify as a direct variation, inverse variation or neither.
y = 6x

Answer 1

@Jack1

Answer 2

direction variation is defined as two variable quantities (in this case, y and x) having a constant/unchanged ratio

Answer 3

Okay... So..? Lol

Answer 4

lol so that means if x increases, then y should do so as well. according to your equation, as x increases by 6, then y will also increase

Answer 5

Here is a webpage that clearly illustrates what I'm trying to say

Answer 6

Also, your equation is y=6x

The formula for direct variation is y=kx, where k represents the constant of variation
as long as k is greater than zero (in other words, positive) we know that x will increase as y increases. therefore making this equation an example of...

Answer 7

^ lol i basically just said it ;-;

Answer 8

perfectly explained @TheGh0st , props

@xo_kansasprincess_xo if it helps: in terms of the last question we went through
V = kP => Direct variation of V to P
V = k/P => Inverse variation of V to P
V = Q => No relationship between V and P

Answer 9

Thanks y'all!

Answer 10

What about this one?

Identify as a direct variation, inverse variation or neither.
If x men can build a house in y days, how do x and y vary?

Answer 11

@TheGh0st @Jack1

Answer 12

think about it this way. the more men you have, the less time it takes to build a house.

So both don't increase...

Answer 13

more men can build a house in less time, so as x goes up, y goes down: this is an inverse variation
if x increases as y increases ==> direct variation
if x increases but y decreases ==> inverse variation

Answer 14

lol, jinks

Answer 15

So neither?

Answer 16

jinks or jinx? xD

Well there is definitely a variation. but it's not direct since one increases as the other decreases

Answer 17

Okay... So inverse

Answer 18

yep :)
