Answer:

Equal to

Step-by-step explanation:

Hello!

Let's simplify the left side:

  • - ( -9 )          
  • 9

Remember that the negative sign also means opposite, so the opposite of negative 9 is positive 9.

Let's simplfy the right side:

  • | - 9 |
  • 9

Remember that in an absolute value bracket, any positive value stays positive, but any negative value turns to the positive value.

So the inequality is 9 _ 9

Therefore the sign should be "=" as 9 is equal to 9.
