Question

if x is inversely proportional to y and x=12 when y=0.4,determine:
a.) the value of x when y=3
b.) the value of y when x= 2

Answer 1

x=k/y where k is some constant..put x=12 and y=0.4 and find k...

Answer 2

:(( huh.. i got confused

Answer 3

12=k/0.4
or k=12*0.4=4.8

Answer 4

now you get x=4.8/y
a)put y=3 and calculate x
b)put x=2 and calculate y

Answer 5

thanks!

Answer 6

got your answers?

Answer 7

therefore the when y=3 then x is1.6
and if x=2 then y is 2.4

Answer 8

well done...

Answer 9

thanks!

Answer 10

i got the answer of is it correct???
