Ok first we can split it in two :

and

.
The derivative of

is 3.
For the first part, we use the chain rule :
![[f(g(x))]'=g'(x)f'(g(x))](https://tex.z-dn.net/?f=%5Bf%28g%28x%29%29%5D%27%3Dg%27%28x%29f%27%28g%28x%29%29)
hence

(since the derivative of the exponential is itself) hence
Its the second one: 5n-3=12
Answer:
y=2x=5
Step-by-step explanation:
the slope of the equation is 2 and the y intercept can be anywhere between -6 and 6 so i just chose 5
the m will equal 10 because 1.2 times 10 equals 12
The answer to your problem that you are stuck on is 4 which is the third option
