Question

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

Answer 1

Answer:

I think the answer is -40

Step-by-step explanation:

1. what I did was added the -20 +-20

Answer 2

Answer:

x=0

Step-by-step 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
