(5x³ + 4x²) - (6x² - 2x - 9)
-1(6x²) -1(-2x) -1(-9) = -6x² + 2x + 9
5x³ + 4x² - 6x² + 2x + 9
5x³ - 2x² + 2x + 9  Choice D.
        
                    
             
        
        
        
Here , we are provided with a table which shows 5 consecutive terms of an arithmetic sequence . But before solving further , let's recall that ; 
The n'th term of a Arithmetic Sequence let's say it be  is given by ;
 is given by ; 
Where , <u>d</u> is the common difference
Now , here we are given with ;
 
 
We have to find the 2nd , 3rd and 4th term respectively , 
Now , by using the above formula , 5th term can be written as ; 
 
 
Putting the values and transposing 1st term to RHS , we have ; 
 
 
 
 
 
 
Now , as we got the common difference , so we can find out the missing terms now ; 
 
 



Now 
 
 



Also ,
 
 



Now , The given table can be written as ;

Answer:
Step-by-step explanation:
perp. -4/3
y + 2 = -4/3(x - 3)
y + 2 = -4/3x + 4
y = -4/3x + 2
