Answer:

Simplifying

4x + -5 = 6x + 5

Reorder the terms:

-5 + 4x = 6x + 5

Reorder the terms:

-5 + 4x = 5 + 6x

Solving

-5 + 4x = 5 + 6x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-6x' to each side of the equation.

-5 + 4x + -6x = 5 + 6x + -6x

Combine like terms: 4x + -6x = -2x

-5 + -2x = 5 + 6x + -6x

Combine like terms: 6x + -6x = 0

-5 + -2x = 5 + 0

-5 + -2x = 5

Add '5' to each side of the equation.

-5 + 5 + -2x = 5 + 5

Combine like terms: -5 + 5 = 0

0 + -2x = 5 + 5

-2x = 5 + 5

Combine like terms: 5 + 5 = 10

-2x = 10

Divide each side by '-2'.

x = -5

Simplifying

x = -5

The grid shows Figure Q and its image Figure Q′ after a transformation.
Svetach [21]

The transformation of pentagon Q to pentagon Q' is a clockwise rotation of 180° about the origin.

<h3>What is transformation?</h3>

A transformation is a general term for four specific ways to manipulate the shape or position of a point, a line, or a geometric figure.

We have,

Coordinates of a pentagon Q.

(2, 4), (3, 7), (7, 5), (5,4), and (4,2).

Coordinates of pentagon Q'.

(-2, -4), (-3, -7), (-7, -5), (-5,-4), and (-4,-2).

We see that the coordinates of each point of the pentagon Q have changed their position as negative coordinates in pentagon Q'

The coordinates of pentagon Q are in (x, y) which can be assumed to be in the first quadrant of the coordinate plane.

The coordinates of pentagon Q' are in (-x, -y) which is in the 3rd quadrant.

From the first quadrant to 3rd quadrant there is a rotation of 180°.

Thus the transformation of pentagon Q to pentagon Q' is a clockwise rotation of 180° about the origin.
