Question

HELP PLEASE!! (attatchment with question) asap! will medal

Answer 1

a direct variation means, something like
y = (some value) * x

like say y = 3x
so if x = 1, y = 3
x = 2, y = 6
x= 3, y = 9 and so on
-----------------------------------------------
inverse variation means
\(y=\frac{some\ number}{x}\qquad \textit{for example}\qquad y=\frac{3}{x}
\qquad
\begin{array}{llll}
x&y
\\\hline\\
1&\frac{3}{1}\to 3\\
2&\frac{3}{2}\\
3&\frac{3}{3}\to 1\\
&\textit{and so on}
\end{array}\)

Answer 2

can you help me with the first one then???

Answer 3

well... what do you think on the first one

notice, "y" seems to always be bigger than "x"

is there any factor for that?

Answer 4

nope so is it inverse?

Answer 5

or neither?

Answer 6

hmmm actually.... "y" fluctuates

Answer 7

what do you mean

Answer 8

it varies.. is up first.. then down... .is bigger than "x", and then it goes smaller

Answer 9

ok so what does that mean

Answer 10

well... looking at their pattern, I don't see a common factor to get an expression on any of of them...thus I'd say neither on all 3
