F ( x ) = 2 x + 3
g ( x ) = x²
Part 1 : f ( g ( x )) = f ( x² ) = 2 x² + 3
Part 2 : g ( f ( x ) ) = g ( 2 x + 3 ) = ( 2 x + 3 )² = 4 x² + 12 x + 9
Part 3:
Both parts represent the composition of functions. In the first part we are plugging function x² into f ( x ) and in the second part we are plugging
2 x + 3 into g ( x ).
There are always two possible unit rates.
Either way, you just divide to find it.
(5 hours) / (216 miles) = 0.023 hours per mile .
(216 miles) / (5 hours) = 43.2 miles per hour .
Answer:

Answer:
Step-by-step explanation:
If <A and <B are vertical Angeles it implies they are equal
: 5x + 2 = 6x - 12
5x - 6x = -12 - 2
-x = - 14
x = 14°
Unit rate = 1230 miles / 5 hours = 246 miles per hour.
