Question

suppose y varies directly with x. write a direct variation equation that relates x and y. then find the value of y when y=15 when x=6

Answer 1

y varies directly with x so

y = kx

when y=15 then x = 6
y = kx
15 = 6x
k = 15/6
k = 5/2

you're missing some info in your question

Answer 2

thats all it says this is ls me but but still helpful

Answer 3

you're sure? it doesnt say what x is? the question should be something like "find y when x is ____"

Answer 4

nothing like that?

Answer 5

i think it may say 7

Answer 6

ahh better

y = kx
find y when x = 7

y = (5/2)(7)
y = 35/2

Answer 7

ok thanks

Answer 8

welcome
