Assume that y varies inversely with x. If y = 7 when x = 2/3, find y when x = 7/3. <br>y = [?] ​
Alekssandra [29.7K]

Answer:

y = 2

Step-by-step explanation:

varies inversely

xy = k

y = 7 when x = 2/3

(2/3)7 = k

14/3 = k

k = 14/3

--------------------

find y when x = 7/3

(7/3)y = 14/3

multiply both sides by 3/7

y = 14/3 * 3/7

y = 2
