Dantes cell phone company charges $45 per month for unlimited calls and internet use and $0.25 per text message his last fell phone bill was $60.50 how many text messages did dante send last month

What is the solution of the systems of equations? y=2/3x+3 x=-2

Use the distributive law to multiply. 3(4x + 5y + 6)

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
