These are questions for a FRESHMAN (they are extremely hard, aren't they?) summer math project and I would really appreciate it if you could help me answer these last few. THANK YOU SO MUCH!!
Answers:21. A variable will have one value for a linear equation (i.e. no squared terms or higher). Something like x + 9 = 11 will only give one value. A variable will have more than one value for any other equation or inequality (x^2 - 5x + 4 = 0, or x + 3 > 99 will give more than one value for x).
Question:what is a site that you can type any math question in and it gives you the answer? i want to check my paper.
