Answer:
<em>y: (0 , 2.5)</em>
<em>x: (3.5 , 0)</em>
Step-by-step explanation:
Y-intercept : (0 , 2.5)
X-intercept: (3.5 , 0)
When looking at the intersection on the y-axis, the x-coordinate will be 0. And when looking at the intersection on the x-axis, the y-coordinate will be 0.
 
        
             
        
        
        
A) set x as the number of cameras
18x=9x+1800
9x=1800
x=200
b) i'm assuming it's increasing production from my answer in a, so the profit would be 18(250)-(9*250+1800)=4500-4050=450
        
             
        
        
        
Answer:
   The quadratic curve has the best correlation to the given data.
Step-by-step explanation:
Enter the data into a spreadsheet or graphing calculator and try the different regression options to see which gives the highest R-value. Here, the quadratic regression does that.
 
        
             
        
        
        
Answer:

Step-by-step explanation:
<em>Find the equation of the dashed line</em>
The line pass through the points
 -----> is the y-intercept of the line
 -----> is the y-intercept of the line

Find the slope of the line m
The formula to calculate the slope between two points is equal to

substitute the values

Remember that
The equation of the line into slope intercept form is equal to

we have

 
  
substitute

<em>Find the inequality</em>
we know that
The solution of the inequality is the shaded area below the dashed line
so
