Answer:
Congrats you are correct.
Step-by-step explanation:
It took a while but i solved it.
Independent: number of hours
Dependent: money earned
Basically, the amount of money she earns DEPENDS on how many hours she worked. It wouldn’t make sense to say that the amount of hours she worked depends on how much money she made.

Answer:</h2>
The simplified form of the given polynomial equation is:
![-2x^2-x+7](https://tex.z-dn.net/?f=-2x%5E2-x%2B7)
<h2>
Step-by-step explanation:</h2>
We are asked to simplify the given polynomial expression in terms of the variable x.
The algebraic expression is given as:
![(-9x^2+2x+13)-(-7x^2+3x+6)](https://tex.z-dn.net/?f=%28-9x%5E2%2B2x%2B13%29-%28-7x%5E2%2B3x%2B6%29)
On taking out the terms from both the brackets the sign of the terms of the second bracket gets interchanged as there is a negative sign preceding it.
Hence, we get the expression as:
![=-9x^2+2x+13+7x^2-3x-6\\](https://tex.z-dn.net/?f=%3D-9x%5E2%2B2x%2B13%2B7x%5E2-3x-6%5C%5C)
Now on combining the like terms we get:
![=-9x^2+7x^2+2x-3x+13-6\\\\\\=-2x^2-x+7](https://tex.z-dn.net/?f=%3D-9x%5E2%2B7x%5E2%2B2x-3x%2B13-6%5C%5C%5C%5C%5C%5C%3D-2x%5E2-x%2B7)
