Expand brackets on LHS4x+12=2x+8Collect "like" terms4x-2x=8-122x=-4Divide both sides by 2 to solve for xx=-4/2=-2Final Answerx=-2
dy/dx = 9x^2 - 12x + 2
To find the velocity from the displacement you must differentiate the function with respect to time.V = (52)t^(2-1) + (21)t^(1-1) + (40)V = 10t +2To find the acceleration you must differentia...
To find the velocity function of a particle when given its displacement function, you must differentiate the given function. v = 6t^2 - 24t + 7 .Similarly, to get the displacement function from the veloci...
