Find constants a and b such that {x + 7}/{x^2 - x - 2} = {a}{x - 2} + {b}{x + 1} for all x such that x is not equal to -1 and that x is not equal to 2. give your answer as the ordered pair (a, b) ! just the answer, .

Solve by any method (graphing, substitution or linear combination)y = x - 82x + 3y = 1a) (2, -6)b) (5, -3)c) (4, -4)d) (0, -8)i figured it out. the answer is (5, -3)

Part a: sam rented a boat at $225 for 2 days. if he rents the same boat for 5 days, he has to pay a total rent of $480. write an equation in the standard form to represent the total rent (y) that sam has to pay for renting the boat for x days. (4 points)

How can i differentiate this equation?
