Which of the following equations are examples of inverse variation? xy=c, cy=x, y=c/x, x=y/c, 1/y=xc

Respuesta :

Answer: [tex]y=\frac{c}{x}[/tex]

Step-by-step explanation:

1. By definition, an inverse variaton is a relationship between two variables:

- When of them increases, the other one decreases.

- When one of them decreases, the other one increases.

2. An inverse variation has the following form:

[tex]y=\frac{k}{x}[/tex] ([tex]y[/tex] is inversely proportional to [tex]x[/tex])

Where [tex]k[/tex] is a nonzero constant.

3. The option that has the form shown above is:

[tex]y=\frac{c}{x}[/tex]

Where [tex]c[/tex] is the nonzero constant.

Answer:

A: xy=c

C: y=c/x
