Answer:
slope = 
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (- 3, 0 ) and (x₂, y₂ ) = (2, 4) ← 2 points on the line
m =  =
 = 
 
        
                    
             
        
        
        
For the given vectors  and
 and 
The dot product of vectors a and b is defined as = 
So, 

= -16+12
= -4
 
        
             
        
        
        
Answer:
27x - 2
Step-by-step explanation:
First off, we use commutative property to get the like terms together.
(20x + 7x) - (3-5)
Now we can solve the equations inside the parenthesis.
27x - (-2)
Because these aren't like terms, this is as far as we can go. Meaning 27x - 2
is out answer.
 
        
             
        
        
        
no. of boys : no.of girls
100 : 140
to get the simplest ratio you gotta divide both with a common factor 
Because both 100 and 140 share a common factor of 20 
the simplest ratio will be
100/20 : 140/20
5:7
5:7 is the simplest ratio
