The graphs of a function f(x)=3x+b and its inverse function f^-1(x) intersect at the point (-3,a). Given that b and a are both integers, what is the value of a?

 

Find the common ratio of the infinite geometric series:

5/6 - 4/9 + 32/135

 

If x, y, and z are positive real numbers satisfying:

log x - log y =a

log y - log z = 15

log z - log x = -7

where a is a real number, what is a?
