Step-by-step explanation:
if b+c=0
b=-c
x^b=x^-c
so
1/[2(x^b)+1]
 
        
             
        
        
        
Answer:
The equation of the line AB is  y - x -4 = 0 
Step-by-step explanation:
The points are A (10,14) and B(2,6)
Now, slope of the line AB :  
or,  =
 =  
 
So, slope of the equation AB = 1
Now, by SLOPE INTERCEPT FORM:
The equation of line is given as :     y - y0 = m (x-x0)
So,the equation of line AB is  y - 6 = 1(x-2)
or, y - 6 -x + 2 = 0
or, y - x -4 = 0 
Hence, the equation of the line AB is  y - x -4 = 0 
 
        
             
        
        
        
Answer:
The student's GPA is of 0.82.
Step-by-step explanation:
GPA:
To find the student's GPA, we find his weighed mean. 
Grades:
7 hours worth 3(B)
6 hours worth 1(D)
20 hours worth 0(F). So

The student's GPA is of 0.82.
