If 44% of the students in a certain college are females and there are 2,640 female students, what is the total number of students

Imogene invested $8,000 in a bank account that pays 8 percent simple interest at the end of each year. her friend invested the same amount in stocks where the growth of the investment is represented as 2,000 times the square root of 2 less than the time lapsed in years. if y1 and y2 represent the amount earned in dollars and t is the time lapsed in years, which system of equations correctly represents the situation?

What are the solutions of the system? solve by graphing. y = -x^2 -6x - 7 y = 2

Solve 3x-18=2y and 5x-6y=6 by elimination show work
