Answer 1

I cannot see the links which need logins.
You may want to copy and paste what's shown in the links.

Answer 2

Ok hold one..

Answer 3

a)

Answer 4

ahh the joy of "flvs" urls, which require a login

fyi, not everyone has an account at flvs, and not everyone with an account ther is logged in flvs website,, and thus unless one is logged in flvs website, for which you'd need an account, for which you'd need to first register, for which you'd need to fill out a form first, then you can't access the secure session or any of its resources

Answer 8

an inverse relation will usually mean "y is decreasing as x is increasing"
check that in the graphs

Answer 9

@jdoe0001 its D I think

Answer 10

hmm, D is a scatter plot..... do you think "y" is getting bigger as "x" moves to the right?

Answer 11

which would be the opposite of "decreasing" of course

Answer 12

@jdoe0001 the graph are kinda confusing so no hold on..

Answer 13

A?

Answer 14

A is a scatter plot
well, is "y decreasing or increasing" as "x increases, or moves to the right"?

Answer 15

An inverse relationship (as defined in your context) is a function in which the product of x and y are constant.
For example,
(4,1)
(2,2)
(1,4)
are points which lie in an inverse function.
The answer is not D.

Answer 16

@mathmate & @jdoe0001 ohhhhhhhhhhh its C sorry omg

Answer 17

let's see C
x = 3, y =12
x = 6 , y used to be 12 now is 24
x = 9, y used to be 24 now is 36

so that'd be a DIRECT VARIATION, "y is increasing with x increment"
so that is NOT an inverse variation

Answer 18

@jdoe0001 so I am right?

Answer 19

what do you think?
is "y increasing or decreasing" as "x" increases in C?

Answer 20

You got it! Well done, Juliette!
