Laplace transform property for convolutions of the type

${\int}_{0}^{x}f(x-y)g(y)\phantom{\rule{thinmathspace}{0ex}}dy$

is very well known. There exists a Laplace transform property to calculate functions of the type below

${\int}_{a}^{x}f(x-y)g(y)\phantom{\rule{thinmathspace}{0ex}}dy,$

when a>0?
