Answer:
The algebraic expression is 80d
Step-by-step explanation:
Maria's earnings per day = $80
Number of days= d
Total earnings for d days:
80d
Where,
80 is earnings per day
d is number of days
The algebraic expression is 80d
Algebraic equation is
y= 80d
Where
y= total income earned in d days
The expression is different from am equation because of the equal to sign(=)
 
        
             
        
        
        
Answer:
B. x =1 , y = -5 
Step-by-step explanation:
So, what we can do is to simply plug in all of the equations and see which one fits. Equation: x - y = 6 
A. x =1 , y = -6 
1 -(-6) = 6 
1 + 6 = 7 
A would be incorrect. 
B. x = 1, y = -5 
1 - (-5) = 6 
1 + 5 = 6 
Therefore, B would be correct.
 
        
                    
             
        
        
        
H(-6) = 2(-6) + 5
h(-6) = -12 + 5
Solution: h(-6) = -7
