Describe what happens to the x' and y-coordinates after a point is reflected across the x- axis

1 answer:

3 0

The y coordinate would become a negative or positive depending on the number. The x coordinate stays the same. For example, if the numbers were (3,2), then they the x coordinate, 3, stays the same and the y coordinate, 2, changes to -2 (negative 2).

Additive inverse of 400

Goshia [24]

Given:

A number is 400.

To find:

The additive inverse of 400.

Solution:

We know that the sum of a number and its additive inverse is 0.

If "a" is number and "b" is its additive inverse, then

$a+b=0$

Let x be the additive inverse of 400. Then,

$400+x=0$

Subtract both sides by 400.

$400+x-400=0-400$

$x=-400$

Therefore, the additive inverse of 400 is $-400$ .
