Given:
The degree of polynomial = 9
Leading coefficient is negative.
To find:
The end behavior of the polynomial.
Solution:
Let the polynomial be P(x).
We have,
Degree of polynomial = 9, which is odd.
Leading coefficient is negative.
If the degree of a polynomial is odd and leading coefficient is negative, then
Therefore, the end behavior of the given polynomial is 
.
36×3/4
we will simplify it in four's table
9×3=27
T= # of rental hours
Multiply number of hours rented by the cost per hour, add that total to the reservation fee. The total needs to be less than $91.
Reservation + ($ per hr * # hrs) < $91
$19 + $6t < $91
subtract 19 from both sides
6t < 72
divide both sides by 6
t < 12
ANSWER: To spend less than $91, they need to rent the room less than 12 hours.
Hope this helps! :)
6x - 3y = 12
3y = 6x -12
y = 2x -4
slope = 2
