Step-by-step explanation:
f°g=




if the denominator is zero the number is undefined which makes it not in the domain of the function
set
equal to 0
the values for x is 0 or 6
so the only value that is not in the domain of f°g is 0 and 6
Hope that helps :)

Let p and w represent the speed of the plane and the speed of the wind, respectively.
.. speed = distance/time
.. p +w = 720/3 = 240
.. p -w = 720/4 = 180
Add the two equations to eliminate w.
.. 2p = 420
.. p = 210
.. w = p -180 = 30
The speed of the wind is 30 mph.
The speed of the plane in still air is 210 mph.
Answer:
11
Step-by-step explanation:
1st plug in the given numbers for each variable (the letters)
4 x 6 ÷ 3 + 3 =
Next, use the order of operations to solve the expression.
4 x 6 ÷ 3 + 3 =
24 ÷ 3 + 3 =
8 + 3 = 11
