Solve for u: 1.5u + 8.0 = 3.5

To solve for "u", you need to isolate/get the variable "u" by itself in the equation:

1.5u + 8.0 = 3.5    Subtract 8.0 on both sides

1.5u + 8.0 - 8.0 = 3.5 - 8.0

1.5u = -4.5      Divide 1.5 on both sides to get "u" by itself

u = -3

PROOF

1.5u + 8.0 = 3.5     Plug in -3 for "u"

1.5(-3) + 8.0 = 3.5

-4.5 + 8.0 = 3.5

3.5 = 3.5

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
