In the year 2006, a person bought a new car for $13500. For each consecutive year after that, the value of the car depreciated by 9%. How much would the car be worth in the year 2009, to the nearest hundred dollars

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions.a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0

Use the elimination method to solve the systems of equations.choose the correct ordered pair. 7x+4y=39

Simplify. 4+3/7x-2-2/7x a. 2-5/7x b. 6-1/7x c. 2+1/7x d. 6+5/7x
