Question

y varies inversely with x
k= 1.25
What is the value of y when x is 5?

Answer 1

Answer:

The value of y is 0.25

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form $y*x=k$ or $y=k/x$

For x=5

Find the value of y

k=1.25

substitute in the equation

$y=k/x$ -----> $y=1.25/5=0.25$
