Answer:
The number of ways are 40320.
Step-by-step explanation:
Consider the provided information.
Ms. Smith keeps eight different cookbooks on a shelf in one of her kitchen cabinets.
We need to determine the number of different ways to put eight cookbooks on the shelf.
We need to select 8 cookbooks taking 8 at a time.
So use the permutation formula: 
Substitute n=8 and simplify.
Hence, the number of ways are 40320.

<em>Hello There. Here is Explanation How to get the answer.</em>
Explanation: x + y = -6 �> x = -6-y
xy = 8
(-6-y)y = 8
-6y - y^2 = 8
y^2+6y+8 = 0
(y+2)(y+4) = 0

Answer:
Number of students tickets sold = x = 380 tickets
Number of adults tickets sold = y = 150 tickets
Step-by-step explanation:
Let
Number of students tickets sold = x
Number of adults tickets sold = y
x + y = 530 (1)
3x + 4y = 1740 (2)
From (1)
x = 530 - y
Substitute x = 530 - y into (2)
3x + 4y = 1740
3(530 - y) + 4y = 1740
1590 - 3y + 4y = 1740
- 3y + 4y = 1740 - 1590
y = 150
Substitute y = 150 into (1)
x + y = 530
x + 150 = 530
x = 530 - 150
x = 380
Number of students tickets sold = x = 380 tickets
Number of adults tickets sold = y = 150 tickets
X - (-150) = 200
x + 150 = 200
x + 150 (-150) = 200 (-150)
x = 200 - 150
x = 50
hope this helps
