Performing laplace transform of the equation.
sY(s) - y(0) + 6Y(s) = 1/(s-4)
(s+6)Y(s) - 2 = 1/(s-4)
Y(s) = 2/(s+6) + 1/(s-4)(s+6), by partial fraction decomposition
Y(s) = 2/(s+6) + 1/10 * (1/(s-4) + 1/(s+6))
Y(s) = 0.1/(s-4) + 2.1/(s+6)
Performing inverse laplace transform,
y(t) = 0.1e^4t + 2.1e^(-6t)

If you're going to use technology (Brainly) to solve this problem, you might find you get a quicker answer using the technology of your graphing calculator.
It is often convenient to cast the problem in the form f(θ) = 0. You can do that by adding 1 to both sides of the equation.

Answer:
i think it is c because its a complete question and sentence if im wrong tell me ( ;
brainlyest would be nice btw ( ;
Step-by-step explanation:
100%-8.5%=91.5%
After tax, the price is 91.5% of original price.
640*91.5%=$585.60
