Question

Find the missing value. y is directly proportional to x and inversely proportional to the square of z. y = 30 when x = 60 and z = 10. Find y when x = 2 and z = 2.

Answer 1

y = k*x/z^2

Answer 2

is this algebra II?

Answer 3

It is precal. and 30=k*60/100?

Answer 4

Dude... ur on ur own

Answer 5

k=18

Answer 6

@perl would this be y=9?

Answer 7

@xapproachesinfinity

Answer 8

y directly proportional to x mean y=kx
the other one @perl gave it to you

Answer 9

wait so we are using direct and indirect?

Answer 10

no you have to use one equation
i just divide the meaning of each
perl gave you the equation above
find k=?
and answer the question for x=2 and z=2

Answer 11

so 30=60/10^2
