Answer 1

do you know the equation for inverse variation ??

Answer 2

yea

Answer 3

y = k/x

Answer 4

okay so replace x and y by their values
use first one x = 8 and y = 10
and find k first

Answer 5

Answer 6

this is like an SAT question

Answer 7

Answer 14

ok hold on

Answer 15

\(\Huge\ddot{\Large\smile}\) okay

Answer 16

10?

Answer 17

nope

Answer 18

I did y=80/8

Answer 19

\[\large\rm y = \frac{ k }{ x }\]
k = 80
x = 6 solve for y

Answer 20

ok

Answer 21

nope x is not 8 this time you have to use 2nd x value
