You decide instead to take the train there. the train will take 135 minutes. convert this into hours and minutes.

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

Write the point-slope form of the line passing through (2, -12) and parallel to y=3x.
