Question

Use k as the constant of proportionality to write the equation expressing the relationship: y varies inversely as x.

If y = 25 and k = 50, what is x?

1/2
2
1,250

Answer 1

Answer: 2

Step-by-step explanation: i got it right :)

Answer 2

y varies inversely as x. this mean x time y = k. We can find x by setting up the equation.

k = xy
Now insert the number we know into the equation. We know y = 25 and k = 50

k = xy
50 = x25
50 = 25x
50 / 25 = 25x/ 25
2 = x
x = 2 <-----answer
