Question

math help ss below

Answer 1

@AZ

Answer 2

when it varies inversely, that means xy = k

when it varies directly, that means y = kx

Answer 3

ok so sqrt(x)*y=k in this case?

Answer 4

Exactly! I guess I should have worded it better

when x varies indirectly with y, then it's written as xy = k

when x varies directly with y, when it's written as y = kx

so yeah

Answer 5

so how would i use this for the problem??

Answer 6

You plug in the values

x = 24 and y = 15, so find the value of 'k' and then once you know the value of k, you plug in y = 3 and solve for x

Answer 7

oh ok
so sqrt(24)*15=30sqrt(6)
so then
sqrt(x)*3=30sqrt(6)
so sqrt(x)=10sqrt(6) and that means x=600?

Answer 8

Yup!

Answer 9

Good job :)

Answer 10

thank u

Answer 11

No problem!
