Find the image of (1,2) after a
reflection about x = 6 followed by a
reflection about x = 4.

(-3,2)

Step-by-step explanation:

When the point P(x,y) is reflected in the line , the mapping is

.

The image of (1,2) after a  reflection about x = 6 is

.

.

.

When the resulting point is again reflected in the line x=4, we obtain

.

.

.

Therefore the image of (1,2) after a

reflection about x = 6 followed by a

reflection about x = 4 is (-3,2)

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}
