Describe a rigid transformation that takes Polygon A to Polygon B. Does Anybody know the answer to this problem? i've been struggling with it a lot and i really want to get it done so any help would be appreciated!

Polygon A is reflected across x- axis followed by the reflection across y-axis.

Step-by-step explanation:

A polygon A has been transformed by a rigid transformation to form an image polygon B.

Let one of the vertex of polygon A is (-2, 1).

When polygon is reflected across the x - axis,

Image point will be,

A(x, y) → A'(x, -y)

By this rule,

A(-2, 1) → A'(-2, -1)

Now the image point is further reflected across the y-axis,

Rule for the reflection across y-axis is,

A'(x, y) → B'(-x, y)

By this rule, image of A' will be,

(-2, -1) → (2, -1)

Therefore, Polygon A is reflected across x- axis followed by the reflection across y-axis.

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
