The value of k

Answer 1

k=4

Answer 2

To solve this problem, we need to use the given equation and the values of x and y. We are given that y=4x and that x=10. Plugging in the value of x, we get:

y=4(10)

y=40

So the value of y is 40 when x is 10. Now, we need to find the value of k. Since we only have one equation and two unknowns, we cannot find the exact value of k. However, we can find an expression for k in terms of y:

k=y/(y-2x)

=40/(40-2(10))

=)40/10

=4

Therefore, the value of k is approximately four. However, it's worth noting that this is an approximation since we only used one equation and two values of x and y.
