Suppose that y varies inversely with x and y = 3 when x=10 find y when x=5

zysi [14]

Answer:

y=1.5

Step-by-step explanation:

if (y = 3) is (x = 10) and (y = ?) is (x = 5) we see that x is half of the first equation in the second. This means we divide both variables in the first equation by half to get the second. [(x = 10) / 2 = (x = 5)] therefor, [(y = 3) / 2 = (y = 1.5)]. Making your answer 1.5.

Hope this helps :)
