Answer 2

so k=1300

Answer 3

would it also y always be in fraction form

Answer 4

if y varies inversely with x then yes. Always makes sure you read what varies with what and in in what way.
So, what do you think?

Answer 5

d

Answer 6

what is the form of y varies inversely with x? including k

Answer 7

I dont think x would be on the

Answer 8

Is it \(y=\frac{k}{x}\) or \(y=\frac{x}{k}\)?

Answer 9

y = x/k

Answer 10

well actually no its the other one

Answer 11

i messed up

Answer 12

y = k/x

Answer 13

Yes, exactly. y = x/k is actually a direct inversion in disguise, because dividing by a constant is just like multiplying by a constant.

Answer 14

Right, so if you plug 1300 in, what do you get?

Answer 15

but you said that was wrong earlier

Answer 16

No, k = 1300 is fine, the question is what is the answer

Answer 17

if we plug
$$
y = \frac{k}{x} \implies y=\frac{1300}{x}
$$
That is not d

Answer 18

its b

Answer 19

Right
