Solve the equation for y-value and choose whether it is a direct variation or inverse variation. xy=7

a) y=7/x direct variation
b) y=x/7 direct variation
c) y=x/7 inverse variation
d) y=7/x inverse variation

Given:

The equation is .

To find:

Whether the given equation is a direct variation or inverse variable.

Solution:

Direct variation: y is directly proportional to x.

Inverse variation: y is inversely proportional to x.

Where, k is the constant of proportionality.

We have,

Divide both sides by x.

It is in the form of inverse variation.

Since and it is inverse variation, therefore the correct option is (d).

step-by-step explanation: lol

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
