If y varies inversely as x and y is 6 when x is 12, what is x when y is 14.4? a.5 b.0.4 c.9.6 d.2.5

(a)

Step-by-step explanation:

Inversely: y = k/x, x = k/y

6 = k/12

k = 72

x = 72/14.4 = 5

a 5

Step-by-step explanation:

The formula for inverse variation is

xy =k

We know y=6 and x=12

12*6 = k

72 =k

xy = 72

We want to find x  when y = 14.4

x*14.4 = 72

Divide each side by 14.4

x*14.4/14,4 = 72/14.4

x =5

for the first question it would be the second answer for the second question it would be the third answer and for the third question it would be the first answer
