Given:  <span>y = x^2 + 6x - 5.  Then a = 1, b = 6 and c = -5.
The x-coord. of the vertex is given by x = -b / (2a), which here is x = -6 / (2*1) = -3.
Use the given formula </span><span>y = x^2 + 6x - 5 to find the value of y when x = -3:
y = (-3)^2 + 6(-3) - 5 = 9 - 18 - 5 = -14
Then the vertex is (-3, -14).</span>
        
             
        
        
        
In math the sum means to add 
        
                    
             
        
        
        
3^x = 729 
log(3^x) = log(729) 
xlog(3) = log(729) 
x = log(729)/log(3) 
x = 6

Answer:
D. 105 students and 150 guests
Step-by-step explanation:
105 students and $1 for each ticket is $105.(105 x 1 = 105)
150 guests and $5 for each ticket is $750.(150 x 5 =750)
$105 + $750 = $855
