Can someone help me on this questions please and thank you!

Rectangle abcd is translated to get rectangle a’b’c’d’. rectangle abcd moves units along the x-axis to get rectangle a’b’c’d’. rectangle abcd moves units along the y-axis to get rectangle a’b’c’d’. the algebraic rule that describes this translation is t(x, y), where x = and y = .

Solve the system of equations. y= 2x y= x^2 - 15

Which is the completely factored from of xy^3-x^3y
