If y varies inversely as x and y = 107 when x = –15, find y when x = 5. round your answer to the nearest hundredth, if necessary.
35.67
321
–321
–35.67

  -321

Step-by-step explanation:

The new value of x is the old value divided by -3. Since y varies inversely, its new value will be the old value divided by 1/-3, equivalently, multiplied by -3:

  (-3)(107) = -321

-321

Step-by-step explanation:

We know that x and y varies inversely, and that when y = 107, x = -15

we can represent this in the following table:

  y                x

107       ⇒   -15

Now we need to know the value of y when x = 5,

  y                x

107       ⇒   -15

 ?         ⇒     5

we find the answer by inverse rule of three: multiply the top quantities (107 by -15) and then divide by the remaining amount (5), this is:

107(-15)/5 = -1605/5 = -321
