Find the coefficient of kinetic friction if a box weighing 80 N is pushed across the floor with an applied force of 30 N.

What are the solutions of the system? y = x^2 + 2x +3y = 4x - 2a. (-1, -6) and (-3, -14)b. (-1, 10) and (3, -6)c. no solutiond. (-1, -6) and (3, 10)

15 and 14.7 are 1 apart, so 15 – 14.7 must be 1.

Solve each quadratic equation by factoring and using the zero product property. x^2 + 18x = 9x
