Answer:
An equation for the nth term of the arithmetic sequence 17, 12, 7, 2 is 17-5n.
Step-by-step explanation:
Given,
first term(a)=17
common difference (d)=t2-t1
 =12-17
 =-5
nth term of the arithmetic sequence = a+n×d
 =17+n×-5
 =17-5n
 
        
             
        
        
        
The answer should be 8+[(2^2)+3]-5
Hope this helps!
 
        
             
        
        
        
Answer:

Step-by-step explanation:
The given system of inequalities are;

and

The point that is a solution will satisfy the two inequalities.
Checking for (1,-5)
 and
 and 
 : True
: True  : True
 : True
This point lies in the solution region.
Checking for (1,5)
 and
 and 
 : False
: False  : False
 : False
This point does not lie in the solution region.
Checking for (5,1)
 and
 and 
 : False
: False  : True
 : True
This point does not lie in the solution region.
Checking for (-1,5)
 and
 and 
 : True
: True  : False
 : False
This point does not lie in the solution region.
