1/(x+5) because the (x-2) is canceled from both the numerator and denominator of the equation.
        
             
        
        
        
Answer:
Part A: 
Part B : x = 15
Part C: Megan purchased 15 books.  
Step-by-step explanation:
Megan earns a rebate each month on completing surveys and books. 
She earns $0.75 for each survey she completes and $1 for each book. Now, last month Megan completed 8 surveys and earned $21.
Part A: If Megan purchased x number of books last month, then the equation that will determine the number of books she purchased, is 
 .......... (1) (Answer)
 .......... (1) (Answer)
Part B: Now, solving equation (1) we get,
6 + x = 21 {Since, 0.75 × 8 = 6}
⇒ 6 + x - 6 = 21 - 6 {Subtracting 6 from each side} {Subtraction property}
⇒ x = 15 (Answer)
Part C: Megan purchased last month 15 books. (Answer)

Answer:
A
Step-by-step explanation:
The equation of the line that passes through the points (-9,-7) and (-12,-2) is
y = -5/3x-22
and 
equation of the line that passes through the points (1, 9) and (6, 6) is 
y = -3/5x+48/5
clearly it is not the same line,
 (lines are not perpendicular)
 (lines are not perpendicular) 
 (not parallel)
 (not parallel)
