Answer:
-7 < -3 because -7 is located to the left of -3 on a number line. 
Step-by-step explanation:
This is because -7 is on the left of the -3. In negatives -3 is greater than -7. If it was positive then 7 would be greater than 3. So the answer is A. -7 < -3 because -7 is located to the left of -3 on a number line

Step-by-step explanation:


Multiply Equation no (1) with 2 and Equation no (2) with 7.







Substitute the value of "y" in Equation no (1) 







 
        
                    
             
        
        
        
The coefficient of x^4 and the leading coefficient is 5
the coefficient of x^2 is -2
the coefficient of x is 8
        
                    
             
        
        
        
It's evident that the first four terms are 4, 4/3, 4/9, and 4/27. So the fourth partial sum of the series is

It's as easy as adding up the fractions, but I bet this is supposed to be an exercise in taking advantage of the fact that the series is geometric and use the well-known formula for computing such a sum.
Multiply the sum by 1/3 and you have

Now subtracting this from 

 gives

That is, all the matching terms will cancel. Now solving for 

, you
have
