Question

Assume y varies inversely as x. If y = 60 when x = 80, find x when y = -20​

Answer 1

x=0

Explanation:

so we are going to first subtract by both sides,

x=80 y=60

-20 -20

------------------------

x=60 y=40

then again,

x= 60 y=40

- 20 -20

---------------------

x=40 y=20

and again,

x=40 y=20

-20 -20

-----------------

x=20 y=0

then lastly again,

x=20 y=0

-20 -20

------------------

x=0 y=-20

ta da, hopefully this is helpful
