Question

LAST ONE GUYS...PLS HELP ASAP!! y is inversely proportional to x. Given that y=10 when x=2, find the value of y when x=5

Answer 1

y = 4

I hope it helps

Explanation:

`y \alpha (1)/(x) \\ y = (k)/(x) \\ 10 = (k)/(2) \\`

`k = 20 \\ y = (20)/(x) = formula \: connecting \\ \: x \: and \: y \\`

`x = 5 \\ y = \\ y = (20)/(x) \\ y = (20)/(5) \\`

`5y = 20 \\ (5y)/(5) = (20)/(5) \\ y = 4`
