If y varies inversely with x, and y = 2 when x = 8, what is k, the constant of proportionality?
y = k/x
now just plug in your values:
2 = k/8
k=16
if y inversely x and y=20 when x=8 what is the constant of varition
To find the constant of proportionality, k, when y varies inversely with x, we can use the formula:
y = k/x
Given that y = 2 when x = 8, we can substitute these values into the equation:
2 = k/8
To solve for k, we can cross multiply:
2 * 8 = k * 1
16 = k
Therefore, the constant of proportionality, k, is 16.
To find the constant of proportionality (k) when y varies inversely with x, we can use the formula for inverse variation:
y = k/x
Given that y = 2 when x = 8, we can substitute these values into the formula:
2 = k/8
To solve for k, we can multiply both sides of the equation by 8:
16 = k
Therefore, the constant of proportionality (k) is 16.
