Answer:
$15 exact!!
Step-by-step explanation:
Have a good day!
I’m not sure but this is what I would do
Runner A (unit rate / constant of proportionality):
54 feet divided by 4.5 seconds = 12 feet per second
Runner B (unit rate / constant of proportionality): 300 feet divided by 20 seconds (It looks like the end point of the line lands between 300 feet and 20 seconds) = 15 feet per second
Unit Rate:
Runner A = 12 feet per second
Runner B = 15 feet per second
Faster Runner:
Runner B is the faster runner as he can run a further distance than Runner A in one second.
Answer:
f(3x + 4) = 5x + 8
⇔ f(3x + 4) = 
⇔ f(3x + 4) = 
⇒ f'(x) = 
=> f(3) =

Answer:
(f•g)(x) = 3x^2 -1/3
Step-by-step explanation:
The solid dot in (f•g)(x) is assumed to mean you want the product of the functions, not their composition. So, ...
(f•g)(x) = f(x)•g(x) = (x -1/3)(3x +1) = x(3x +1) -1/3(3x +1) = 3x^2 +x -x -1/3
(f•g)(x) = 3x^2 -1/3
