Find the constant of proportionality (r) in the equation y=rx

ahrayia [7]

Answer:

r = $\frac{1}{4}$

Step-by-step explanation:

Given the proportional equation

y = rx ← r is the constant of proportion

Divide both sides by x

$\frac{y}{x}$ = r

Use any ordered pair from the table.

Using (8, 2 ) , then

r = $\frac{2}{8}$ = $\frac{1}{4}$

What is the relation between the variables in the equation x^4/y=7?

makkiz [27]

Answer:

So, the relation between variables are

$y=\frac{x^4}{7}$

Step-by-step explanation:

We are given

$\frac{x^4}{y}=7$

Since, we have to find relation between variables

so, we can solve for y

$\frac{x^4}{y}=7$

Firstly, we will multiply both sides by y

$\frac{x^4}{y}\times y=7\times y$

we can simplify it

$x^4=7\times y$

we can isolate y

so, we can divide both sides by 7

so, we get

$y=\frac{x^4}{7}$
