What is the additive inverse of the polynomial –9xy2 + 6x2y – 5x3? 9xy2 – 6x2y + 5x3
9, xy, 2, – 6, x, 2, y, + 5, x, 3

–9xy2 – 6x2y – 5x3
–9, xy, 2, – 6, x, 2, y, – 5, x, 3

9xy2 + 6x2y + 5x3
9, xy, 2, + 6, x, 2, y, + 5, x, 3

–9xy2 – 6x2y + 5x3

y=1/4x-4

step-by-step explanation:

it is rigid.; it is isometric. ; the size is preserved.

step-by-step explanation:

a translation is called an isometry; these are transformations that preserve congruence between pre-images and images.

they are also called rigid transformations, as the only thing that can happen to a pre-image is that it is moved or turned, not stretched or shrunk.

since congruence is preserved, the size is preserved.
