Question

Suppose that y varies inversely with x, and y = 6 when x = 7. (search it on brainly and type it for the answer, I can't search on brainly it's blocked).

Answer 1

Answer:

$k=42$

Step-by-step explanation:

y ∝ 1/x

making an equation from the equation above, we can assume:

y = K/x Where k is a constant

Let's clear K

K = xy

If y = 6 when x = 7, then:

K = (7)(6) = 42

Verifying

y = K/x

y = 42 / 7 = 6
