Y = mx+b
-1 = 13/4 (-1) +b 
-4/4 + 13/4 = b
9/4 = b
        
             
        
        
        
Answer:
The answer is One hundred and ten
 
        
             
        
        
        
C=3.14 • d
3.14 is pi as a number but it’s non ending :3
D is diameter
C is circumference 
Since it said the product of pi and diameter it means d or diameter times pi is c or circumference.
So if 
D= i don’t n know maybe 5 find what’s c or te circumference.
So 5 multiplyed by pi or 3.14 is your circumference!
If u need help with the problem please don’t hesitate to ask me! And am purely her to help!!! :3
 
        
                    
             
        
        
        
Answer:
n=-6
Step-by-step explanation:
2(n+5)=-2
distribute
2(n+5)
2xn 2x5
2n+10
2n+10=-2
subtract 10 from both sides
10-10=0
-2-10=-12
2n=-12
divide each side by 2
2n/2=n
-12/2=-6
n=-6
 
        
             
        
        
        
The answer is 18 because you keep 6/1 Chang division to multiplication then flip 1/3 to 3/1 then solve it which again the answer is 18 ;)
