Y=76 x-18
should be the anwer.
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.
Answer:
(- 1, 0) and (9, 0 )
Step-by-step explanation:
To find the x- intercepts let y = 0 in the equation and solve for x, that is
x² + y² - 8x - 8y - 9 = 0
x² - 8x - 9 = 0 ← in standard form
(x - 9)(x + 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 9 =0 ⇒ x = 9
x + 1 = 0 ⇒ x = - 1
x- intercepts are (- 1, 0 ) and (9, 0 )
