Answer:
fgh(x)=4
-14
Step-by-step explanation:
when solving composite fuctions we go from the right to the left
meaning we replace the x in the g function with the entire h function
then replace the x in the f function with the entire new g function
h(x)=
g(
)=
-5
f(
-5)=4(
-5)+6
f(
-5)=4
-20+6
fgh(x)=4
-14
Because Jon is walking at a constant rate, the equation will be simple division. Because Jon walks 3 miles per hour, if you divide 12 miles by 3 miles per hour (12 mi / 3 mph), the miles in the equation cancel and you are left with 12 / 3 hours. 12 / 3 = 4, so Jon is hiking for 4 hours.
