The answer would be 54, because A= PQ over 2 = 9 x 12 over 2 = 54
        
             
        
        
        
Answer:
(in attachment)
Step-by-step explanation:
you can find the points by inputting the x-values into the equation to solve for the y-values, then connecting the plotted points to create the line. 
When x=-4
y=1/2(-4)
y=-2
(-4,-2)
Repeat for all values. 
 
        
             
        
        
        
Step-by-step explanation:
<h2>y = √—16x²+8x—2√8x+1+2</h2>
 
        
             
        
        
        
Answer:
25,600
Step-by-step explanation:
You can use the rule of three considering that the number of dolls sold varies directly with the advertising budget:
$54,000    →   9,600
$144,000   →       x

x=25,600
According to this, the number of dolls sold if the amount of advertising budget is increased to $144,000 is 25,600.
 
        
             
        
        
        
It’s 14.
The five numbers will be: 12, 13, 14, 15, and 17 so 14 is the median.
