How do I find the solutions to 2 graph equations and how do I solve these 2 fraction division problems?
15. What is the solution to the system of equations x^2-x + 6 = y and 2x+2y = 36?
A. (0, 6), (9, 9)
B. (2, square root of 3, 18-2 square root of 3),(-2square root of 3, 18 + square root of 3)
C. an infinite number of solutions
D. no solution
23.((x^2)-x)/((X^2)+3x+2) divided by ((x^2)+(2x))/((X^2)-1) =
25. ((a^2/3)(b^3)c^5)/((a^2)(b^1/3)) divided by (a^2)(b^1/5)(d^1/2)
These questions are from this page: http://www.thea.nesinc.com/practice.htm. I think it's easier to read there.
