Answer: (f+g)(x)=2x^2+2x-2

Step-by-step explanation:

Given the function f(x), which is:

f(x)=-x^2 +6x-1

And the function g(x), which is:

g(x) =3x^2-4x-1

You can observe that (f+g)(x) indicates that you need to add the functions, then you know that:

(f+g) (x)=(-x^2+6 x-1)+(3x^2-4x-1)

Finally, to simplify it you must addthe like terms. Therefore, you get that  (f+g)(x) is:

(f+g)(x)=-x^2+6 x-1+3x^2-4x-1

(f+g)(x)=2x^2+2x-2

2 planes fly in opposite directions. One travels 475 mi/h and the other 525 mi/h . How long will it take before they are 6,000 m
pychu [463]
The speed at which they are moving apart = 475 + 525 = 1000 mi/h

Time  = distance / speed
         = 6000 / 1000  = 6 hours

The answer is 6 hours.
