Answer:
<u>Option D is answer.</u>
Step-by-step explanation:
Hi there!
From the question;
Speed (s) = 600 miles/hr
Distance (d) = 3000 miles
Time (t) = ?
We know that;
Speed (s) = 
600 = 
t = 
Therefore, it will take 5 hours to fly 3000 miles.
Hope its helps!

Answer:
g(f(-4)) = -8
f(g(x)) = 13-10x
Step-by-step explanation:
g(f(-4)):
Plug in the equation f(x) into the variable x of g(x), we have:

Plug in x = -4 and the answer is -8
f(g(x)):
Plug in the equation g(x) into the variable x of f(x), we have:

let's firstly convert the mixed fractions to improper fractions and then multiply.
