2 answers:

8 0

Y = 2x - 4
y = x + 2

2x - 4 = x + 2
2x - x = 2 + 4
x = 6

substitute x = 6 into one of the first 2 equation, i chose the 2nd one.
y = 6 + 2
y = 8

Does (lnk)/(k^3), where as k starts at one and continues on to infinity, converge? ...?

max2010maxim [7]

Yes. The numerator does not increase as fast as the denominator increases, causing the function's value to decrease with every subsequent increase in the value of k. This causes the function to converge at a point.
