Answer:
7,173
x = 7
Step-by-step explanation:
Within the question it gives two examples.
x = 0 corresponds to 2000
x = 1 corresponds to 2001
If you pay close attention the x-value is always the same as the last digits in the year. So with 2007 the last digit is 7, which then leads us to determine that 
x = 7
f (x) = -327 (7) + 9462
f (x) = -2289 + 9462 = 7173
 
        
             
        
        
        
-9 is the slope of the line.
        
                    
             
        
        
        
Answer:
-2/3x
Step-by-step explanation:
1.) use the slope equation (y2-y1)/(x2-x1)
2.) substitute the points into the equation (2-4)/(2--1)
3.) solve the equation (2-4= -2) / (2--1=3)
4.) the slope is -2/3
 
        
             
        
        
        
For the parallel lines 1/2 the vertical line is 1 & the horizontal line is 2 so if you multiply both of them should equal 3. I don't acually know about the other one though
        
             
        
        
        
2.4 in^2 is the area of the triangles and the angle of the rectangle is 7.48 in^2 so the total area is 7.88 in^2
