Question

x and y vary inversely, and y = 3 when x = 6. Find y when x = 9.


A. 2
B. 4.5
C. 12
D. 18

Answer 1

they both vary inversely, to "vary inversely" meaning, when one INCREASES the other DECREASES, so the increment in one, decreases the other

Answer 2

if "x" was 6, and now it WENT UP to 9, so, "y" would?

Answer 3

Go down 3?

Answer 4

the pattern of varying inversely, pretty much rules out 3 of your choices

yes, it goes BELOW its previous standing, below 3

Answer 5

The only thing less the three is two though... SO would it have to be 2?

Answer 6

yes

Answer 7

When you have eliminated the impossible, whatever remains, however improbable, must be the truth.
