A particle moves along the x-axis so that at time t its position is given by s(t) = (t + 3)(t -1)3, t > 0. For what values of t is the velocity of the particle increasing? (2 points)

50 will mark show all use the linear combination method to solve the system of equations. explain each step of your solution. if steps are not explained, you will not receive credit for that step. 2x+9y= -26 -3x-7y=13
