Answer:
y = 2x - 3
Step-by-step explanation:
Since the equation for the line y = 2x + 5 is already in slope-intercept form (y = mx + b), the slope (m) is 2. A parallel line will have the same slope. Now use point-slope formula to find an equation for the parallel line including point (3,3). Point-slope formula is:  
(y – y₁) = m(x – x₁), where m is the slope (2) and (x₁, y₁) is the point the line passes through (3,3).  
Therefore:  
(y – 3) = 2 (x – 3)
y – 3 = 2x – 6
y – 3 + 3 = 2x – 6 + 3
y = 2x - 3

There are 8 weeks and 18 books. therefore you would multiply these numbers together. 
the answer would be 144 different combinations.
not sure about the permutation or combination notation, but I got you on the first part!
        
             
        
        
        
its C 
Step-by-step explanation:
- 2\sqrt5
this is the tan©
but you have to multiply by sqrt 5 
so its become -2sqrt5/5
