70=A=Lw

L=2w-4

70=(2w-4)w

70=2w²-4w

70=2(w²-2w)

35=w²-2w

0=w²-2w-35

0=(w+7)(w-5)

-7=w or w=5

Measurements aren't negative

w=5 ft

L=2(5)-4

L=6 ft

What is the image of (2,3)(2,3) after a reflection over the line y=-xy=−x?
saw5 [17]

Answer:

The image of (2,3) after a reflection over the given line will be: (-3,-2)

Step-by-step explanation:

The given point is (2,3)

Let (x,y) be a point, when it will be reflected over the line y=-x the coordinates are exchanged and are negated i.e. point (x,y) becomes (-y,-x)

When a point is reflected over a line the distance between the image of point and the line remains the same as the distance between original point and line.

Given point will become: (-3,-2)

Hence,

The image of (2,3) after a reflection over the given line will be: (-3,-2)
