Answer: 
m= masters degree salary and b=bachelors degree salary.
 
m = 2b - 45000
m + b = 112000
 
Substitute to get
2b - 45000 + b = 112000
3b = 156000
b = 52000
 
So m = 59000
 
Check to see if these numbers work
59000 = 2*52000 - 45000 true
59000 + 52000 = 112000 true

Attach it plz or I can't help
Step-by-step explanation:
 
        
                    
             
        
        
        
AD is perpendicular to BC so slope Ad = -1/slope of BC
Slope of BC = (2 - (-1)) / (- 6- 3) = 3 / -9 = -1/3
So slope of AD = -1 / (-1/3) = -3/-1 = 3 Answer
 
        
             
        
        
        
No because it would be
if you knew that
ax^2+bx+c was a trinomial square, then the factored form would be

 or 

so 
if w^2-9w+81 is perfect square, factored form is either 

 or 

  aka 

 or  
 
 expand them
(x+9)^2=x^2+18x+81, wron middle term
(x-9)^2=x^2-18x+81 wrong
so it is not
 
        
        
        
Set up a ratio for this problem:
.25 in/50 miles = 2.5 in/x
.25x = 125
then divide by .25
The actual distance is: 500 miles
