The value of a precious gem stone has increased at a rate of 120% each year. if the gems's value started at $50 in 1920, how much will it be worth in 2008?

Which system of linear inequalities is represented by the graph?

Can anyone me with 32,33,36,37,and 40.

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
