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

Answer:

y = 4

I hope it helps

Step-by-step explanation:

$y \alpha \frac{1}{x} \\ y = \frac{k}{x} \\ 10 = \frac{k}{2}$

$k = 20 \\ y = \frac{20}{x} = formula \: connecting \\ \: x \: and \: y$

$x = 5 \\ y = \\ y = \frac{20}{x} \\ y = \frac{20}{5}$

$5y = 20 \\ \frac{5y}{5} = \frac{20}{5} \\ y = 4$
