Answer:
y= CC-4.5x^2
Step-by-step explanation:
To find the general solution to the differential equation
dy + 9x dx = 0, we employ the method of separating variable as follows:
Note: { will represent the integral sign here.
Separating the variables and integrating, we have
{dy = -{9x dx
y = -(9/2)(x^2) + CC,
where CC is the given constant of integration.
This can be rearranged/simplified to yield
y= CC-4.5x^2
Free movie, F = 87pts
Initial reward, I = 10pts
Additional reward, A = 7pts
Movie visit, X
F = I + XA
87 = 10 + 7X
X = (87-10)/7
X = 11
After 11 movie visits Andrew will have enough points for a free movie.
