X^2-13x+40
X^2-8x-5x+40
X(x-8)-5(x-8)
(X-5)(x-8)
        
             
        
        
        
Remember the chain rule.
L(x)=f(g(x))
L'(x)=f'(g(x))g'(x)
take the derivative of f(g(x)). just treat them like they are variables. so you get:
h'=f'(g(x))g'(x)
now plug in your x value and evaluate:
h'(1)=f'(g(1))(g'(1))
substitute in values that you know and evaluate again
h'(1)=f'(3)(-3)
h'(1)=(-5)(-3)=15
 
        
        
        
Answer:
3
Step-by-step explanation:
You use the formula 
y2-y1/x2-x1
I found the points (0, 4) and (1, 7) 
subtracted and divided I got three 
I hope this helps :)
 
        
             
        
        
        
Hello there! How are you today?
First, let's take a look at our numbers.
45 / 100
Both of these numbers have a 0 and a 5, which means it is divisible by 5. 
Let's divide both of them by 5.
45 / 5 = 9
100 / 5 = 20
We are now left with 9/20. 
This is your simplified fraction since 9 and 20 do not have any common factors.
I hope this helps!
