Question

y varies inversely with twice the value of x. When y = 10, x = 3. Find y when x = 5.
help me please

Answer 1

The equation is y = k(2x)

If y = 10, x = 3, then plug these 2 numbers in to the equation to find k.
10 = k(6)
k = 10/6

Now we know k = 10/6 or 5/3, so our equation is y = (5/3)(2x)

Lets now answer the question...find y, when x = 5,
so y = (5/3) (10)
y = 50/3.
