No they are only there so u can understand and answer the questions
Hello!
2y(4-x)=x/2
<span>[plug in 2 for x] </span>
<span>2y(4-2)=2/2 </span>
<span>[4-2 is 2, 2/2 is 1] </span>
<span>2y(2)=1 </span>
<span>[divide both sides by 2] </span>
<span>2y=1/2 </span>
<span>[divide by 2 again] </span>
<span>y=1/4
</span>
====>So As Result As We See, y = 1/4.<====
Hope this Helps! Have A WONDERFUL Rest Of Your Day! :)

△DEF is rotated about point N to △D′E′F′.
A rotation is a transformation that turns a figure about a fixed point called the center of rotation. In your case the center of rotation is point N. A rotation is an isometric transformation: the original figure and the image are congruent. Main properties of rotation:
1) A rotation preserves lengths of segments.
2) A rotation preserves degrees of angles.
3) A rotation maps a line to a line, a ray to a ray, a segment to a segment, and an angle to an angle.
Therefore, option C is true (because the original figure and the image are congruent) and option D is false (because the original figure and the image must be congruent).
All corresponding points on the image and pre-image are equidistant to point N. This option is true (because rotation preserves lengths of segments), thus, DN≅D'N'.
Using the commutative property of addition, and since we simply add the numbers together in parenthesis, they do not
