The average cost of microdermabrasion is $143, according to 2014 statistics from the American Society of Plastic Surgeons.The cost of microdermabrasion treatment can vary. The average fee referenced above does not include anesthesia, facilities or other related expenses.rices may also be based on the expertise and qualifications of the person performing the treatment, type of microdermabrasion procedure performed, time and effort the procedure requires, and the geographic location of the office.
A linear transformation is a transformation of the form X' = a + bX. If a measurement system approximated an interval scale before the linear transformation, it will approximate it to the same degree after the linear transformation. Other properties of the distribution are similarly unaffected.

If it contains only the zero vector, then the linear transformation is one to one and hence an isomorphism (as the two spaces in question are of the same finite dimension).Clearly, $ker T=\{(x,y):T(x,y)=(0,0)\}=\{(x,y):(x-y,x+y)=(0,0)\}=\{(x,y):x-y=0,x+y=0\}$.y the definition the linear isomorphism is a linear bijective map. We should show that for any point $(x,y)\in \mathbb R^2$ there exists unique point $(x',y')\in \mathbb R^2$ such that $f(x',y') = (x,y)$ (this point is called pre-image of $(x,y)$). Note that these any + unique are properties of a bijection.
