5. Which statement is true about a transformation of point (x, y)?
А
(x, y) ='(-x, y) reflects the point across the y-axis.
B (x, y) → (-x, y) reflects the point across the x-axis.
с (x, y) + (-x, y) rotates the point 90° clockwise.
D (x, y) = (-x, y) rotates the point 270° clockwise.

Select the correct answer from each drop-down menu. consider the following polynomials equations. 3x^2(x-1) and -3x^3+ 4x^2-2x+1 perform each operation and determine if the result is a polynomial. is the result of a + b a polynomial? yes or no is the result of a - b a polynomial? yes or no is the result of a · b a polynomial? yes or no
