On the attachment are 25 problems that need to be Solved completely in detail for me.

- Some may involve graphing.

- Also, they must be solved in Word using Equation Editor or similar. No hand written solving please, because I can not read scanned documents on my computer.

- Also, must be solved using Algebra concepts only, not Calculus or other methods.

Please see attachment more details to see if you can help.

THANKS!
