I find it best to switch everything exponents when taking derivatives.
F(x) = 7/x
Same as..
F(x) = 7x^-1
Take derivative..
F'(x) = -7x^-2
Plug in x = 1
F'(1) = -7(1)^-2
F'(1) = -7
The marks are by 1 so just count

Step-by-step explanation:
Coordinates of end points are;
(2,11)
(6.6,8.7)
(9,4)
Each solution region is unbounded.
The final solution region is bonded.
let x = the price of a book
so you would have
total = 3x-20
No triangle. Scalene triangles are all uneven sides.
