Question

Given x varies inversely with y and xy= 2, what is the value of z when y = 1?
A- -1
B- - 1/2
C- 1
D - 2 I’ll give brainlist :)

Answer 1

The answer is D because x=2 when you plug in 1 for y and solve

Answer 2

Answer:

Option D

Step-by-step explanation:

Given x varies inversely with y and xy= 2

When x varies inversely with y then equation is $x=\frac{k}{y}$

Multiply by y on both sides

$xy=k$

Given xy=2, so k=2

The equation becomes $x=\frac{2}{y}$

Plug in 1 for y and find out x

$x=\frac{2}{1}$

x=2
