Answer:

y = 12

Step-by-step explanation:

set up equation for 'y varies inversely with x':  y = k/x

where 'k' is the constant of variation

8 = k/6

therefore, k = 48

value of y when x = 4:  y = 48/4; therefore, y = 12

Thevalue of y when x is 4 is 12

If y varies inversely as x, this is expressed as;

  • y  = k/x
  • k is the variation constant

If x = 8 and y=6

k = xy

k = 8 * 6

k = 48

To get the value of y when x = 4

y = k/x

y = 48/4

y = 12

Hence the value of y when x is 4 is 12
