The point a(4,10) is reflected across the x axis. where is a?

Reflection across the x-axis puts the image point as far below the x-axis as the original is above. That is, it changes the sign of the y-coordinate.

The image of A(4, 10) is A'(4, -10).

Selection c. (4, -10) is appropriate.

can you add an image ?

step-by-step explanation:

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
