Solve.
4k + 2/5 = -2/3
What is k = -4/15?
4k + 2/5 = -2/3
4k = -2/3 -2/5
4k = -16/15
k = -16/15 x 1/4
k = - 16/60
k = -4/15

The distance, in meters, an object will fall after t seconds can be approximated by the equation d=t(4.9t + v), where v is the initial velocity. What was the initial velocity of an object that has fallen 53.4 m after 4 s?
What is v = -6.25 m/s?
d=t(4.9t + v)
53.4 = 4(4.9x4 + v)
53.4 = 4v + 78.4
4v = 53.4 - 78.4
4v = -25
v = -6.25
