Answer:

<h2>10+2x=4</h2>

first, by using inverse operations subtract 10 on both sides.

<h2>10-10+2x=4-10</h2>

4-10 is -6. whys the 6 negative? because the number takes the sign of the bigge number.

<h2>2x=-6</h2>

Divide by 2 to isolate x

<h2>2x÷2=-6÷2</h2>

In multiplication and division one negative sign stays and 2 negative signs cancel eachother but here theres only one negative sign so;

Which graph represents an odd function?
Nookie1986 [14]

Answer:

<h2>The first graph in the second image is an odd function.</h2>

Step-by-step explanation:

An odd function has a graph that it's symmetric about the origin, that is, the origin is like a mirror. In other words, the graph of an odd function has a specific symmetry about the origin.

So, we have to look for those graph that has symmetrical points in opposite quadrants, I and III or II and IV.

You can observe that the first graph of the second image has this behaviour. You can see that the points are symmetrical across the origin. If you graph a line defined as y=-x, you will observe that such line acts like a mirror.

Therefore, the odd function is the first graph in the second image.
