Question

xy = –16. What is the constant of variation for this relationship?



A.-6




B.-1.6




C.1/4




D.-0.16

Answer 1

and i will give medal to the best answer and explanation

Answer 2

General form of inverse variation equations

x*y = k

k is the constant of variation

Answer 3

x*y = k can be rewritten into \(\LARGE y = \frac{k}{x}\) after solving for x

Answer 4

ok i got it written down what next?

Answer 5

can you give me the answer so i can check my work? then i will give you a medal.

Answer 6

jim_thomsan?

Answer 7

the answer is practically given to you

compare x*y = k to the equation you have x*y = -16

you'll see what the value of k must be

Answer 8

so -16 is the answer

Answer 9

no not that

Answer 10

-6

Answer 11

jim?

Answer 12

jim_thopson 5910?

Answer 13

yeah k = -16

Answer 14

so -16 is the constant of variation
