Question

what is indirect variation or inverse variation

Answer 1

it's when:

xy=k

where k is a constant

Answer 2

I know that k s always the constant. But explain indirect or inverse variation

Answer 3

Okay... so in indirect variation.. the x value decreases when the y value increases and vice versa.. in direct variation.. as one value increases so does the other:

inverse: xy=k
direct: x/y=k

Answer 4

Can u do a problem using indirect variation-show me how to work it out if it is a word problem?? Thanks

Answer 5

it would be really nice help if you could

Answer 6

yeah sure.. what is it?

Answer 7

lets say your problem is y varies inversely with x, and y is 34 and x is 14, find y when x is 18

Answer 8

xy=k
34(14)=k
476=k

18y=476
y=26.444444444

Answer 9

so youre basically dividing each side by 18?

Answer 10

yes... :)
