Question

Question 2.2. Find the constant of variation for the relationship shown in the following table:

x 1 2 3 4
y 4 8 12 16

(Points : 1)
1
2
3
4

Answer 1

5. Which does not show a direct variation between x and y?
(Points : 1)
Y= 4/x
y=0.5x
y=x/9
y=7x

Answer 2

help please

Answer 3

x \(\bf {\color{blue}{ 1}}\) 2 3 4
y \(\bf {\color{blue}{ 4}}\) 8 12 16

\(\bf \begin{array}{llll}
\textit{something }&\textit{varies directly to }&\textit{something else}\\ \quad \\
\textit{something }&=(\textit{some value })&\textit{something else}\\ \quad \\
y&=(n)&x
\end{array}\\ \quad \\

x={\color{blue}{ 1}}\qquad y={\color{blue}{ 4}}\qquad y=(n)x\implies {\color{blue}{ 4}}=(n)\cdot {\color{blue}{ 1}}\)

solve for "n", "n" being the "constant of variation"

Answer 4

so its 4

Answer 5

yes

Answer 6

"Which does not show a direct variation between x and y? "

well, keep in mind that \(\bf \textit{direct variation}\implies y=(n)x\qquad \textit{inverse variation}\implies y=\cfrac{(n)}{x}\)

Answer 7

thank u and i no number 2
