Question

Determine whether y varies directly with x. if so, find the constant variation of k.?

x l y
4 l 6.4
7 l 11.2
10 l 16
13 l 20.8

Answer 1

"something" varies directly with "something else" just means
as "something else" changes, the changes affect also "something"
by some factor, usually you'd say "k"

what the smokes is all that?

y = (k) x
any changes to "x", will affect "y"

what's "k"? we dunno
but we know that from the table you provided when x = 10, y = 16
so we can say that

y = (k) x # x = 10, y = 16
16 = k (10)

solve for "k"

Answer 2

"mind blown"

Answer 3

you can't solve for "k"
or you didn't get what I meant?

Answer 4

so I do 16 x 10?

Answer 5

yeap, that's K

Answer 6

k=160?

Answer 7

ohh ... shoot, ... ahemm no

Answer 8

I didn't even notice heheh, anhohw, no
what you want is to isolate K

Answer 9

say , if you had to solve

4 = 2x

for "x", what would you get?

Answer 10

I just need the equation

Answer 11

well, you'd just need to find "k"

Answer 12
