Question

If y is inversely proportional to x and y = 5 when x = 2, find
(i) the value of y when x = 8,
(ii) an equation connecting x and y,
(iii) the value of x when y = 10.​

Answer 1

Answer:

formula = y= k/x

k = y/x

y= 5 , x= 2

k = 5/2

part a

y = 2/5 × 8    =   3.2

part b

y = $\frac{5}{2}$ × x

part c

x = k/y

x = $\frac{2}{5}$ × 10   = 4

hope it helps
