Triangle ABC goes through a series of three transformations. Vertex A has coordinates (2,-3) Find the coordinates of A’ after a 180 degree rotation about the origin A’’ afer A’ is reflected over the x-axis A’’’ after A’’ is reflected over the y-axis

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.

It means if x is -1 what is y then . check -1 on x axis and then check the value of y when x is -1
