Answer:

Step-by-step explanation:
You are being asked to draw the reflection of the triangle DKW.
As with a reflection in a mirror, the reflected object appears to be as far behind the mirror as the original object is in front of the mirror.
When you reflect a point across a line, the image is as far from the line on the other side as the original point is from the line. When the line of reflection is a vertical line, as here (x = 0 = y-axis), the y-coordinates are unchanged.
Points W and K are 2 units to the right of the y-axis. Their reflections will lie on the same horizontal line, but will be 2 units to the left of the y-axis.
Point D is 5 units to the right of the y-axis, so its reflection will be 5 units to the left.

<em>Additional comment</em>
The original triangle and its reflection are symmetrical about the line of reflection.
Answer:
When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x). the line y = -x is the point (-y, -x).
Answer:
-5x/125 is the correct answer
X=-b+-sqrt (b^2-4ac)/2a
x=-11+-sqrt (11^2-4(8)(-300)/16
x=-11+-sqrt (121+9600)/16
x=-11+-sqrt (9721)/16
x=-11+-98.6/16
x=5.48 or x=-6.85
