Question

Anything good mathematicians out there? Need help (brainliest + points)

The variables x and y vary inversely with a constant of variation of 6. Find y when x = 12.

A.
1/4
B.
1/2
C.
2

D.
3

Answer 1

Answer:

B

Step-by-step explanation:

Given that x and y vary inversely then the equation relating them is

y = $\frac{k}{x}$ ← k is the constant of variation

here we are given k = 6, thus

y = $\frac{6}{x}$ ← equation of variation

When x = 12, then

y = $\frac{6}{12}$ = $\frac{1}{2}$ → B

Answer 2

Answer:

$\boxed{\text{B. }\frac{1 }{2 } }$

Step-by-step explanation:

y = 6/x

Let x = 12, Then,

y = 6/12 = ½

When x = 12, y = \boxed{\frac{1 }{2 } }
