Answer:
day 0, day 120
Step-by-step explanation:
You want to find the value of x that makes both y-values be the same:
y = y
30x +10 = -x^2 +150x +10
x^2-120x = 0 . . . . subtract the right side of the equation
x(x -120) = 0 . . . . . factor
Values of x that make this true are x=0 and x=120.
The same number of each car was sold on day 0 and day 120.

I might not be correct please let me know !! But as of right now I think the answer is
-(4x-9)
Answer:
It is only 1 and 2 that is the solution to the differential equation
Step-by-step explanation:
1. x''=- 2 Cos t+ 3 sin t and x=2 cos t -3 sin t the addition give 0
2. d^2y/dx^2=- Sin x +2 and y =Sin x +x^2 the addition =x^2+2
but
3. dx/dt= -2 Sin 2t and tx =t Cos 2t =t( 2Cos t - 2 Sin t) the addition it can't equal Sin 2t
