Answer:
Step-by-step explanation:
Take an easier number.  Suppose you owe your mother = 10 dollars and your father 15. Which one is the bigger debt? Isn't it your father.? So how do you represent the two debts.
Father = - 15
Mother = - 10
Which number is bigger? - 10. Remember the question is bigger. You would rather own just 10 dollars.
So which number is "larger"? 
Isn't it -4488. If it was money and you owed it, would it be the debt you would rather have than -4820
 
        
             
        
        
        
Answer:

Step-by-step explanation:
The vertex form of an equation of a parabola y = ax² + bx + c:

(h, k) - vertex

We have the equation:

Substitute:

Finally:

 
        
             
        
        
        
Unless you're given the value of the variables, you can't really solve for anything. The only thing you can do is simplify. 
<span>39+5h+4g-2h
The only like terms are 5h and -2h.
39 + 3h + 4g
This would be the simplified version.</span>
        
                    
             
        
        
        
For these problems you have to use PEMDAS so for problem 15 you would do the parentheses first, (21-3) you get 18 and then exponents, 3^2, you get 9, no multiplication but there is division so take your answers, 18 and 9 and divide them, you get 2, so the answer to 15 is 2.
