Answer:
The pre-image of the quadrilateral is attached.
Step-by-step explanation:
Each point (x, y) is rotated with the rule (x, y) -> (-x, -y).
So, point W'(2, 3) was W(-2, -3) before rotation.
X'(6, 3) was X(-6, -3)
Y'(6, 4) was Y(-6, -4).
Z'(3, 5) was Z(-3, -5).
The pre-image of the quadrilateral is attached.
Once you get to 0 that is the decimal
Answer:
t = cost of a ticket
4t+55
Step-by-step explanation:
Cost 1
4 airline tickets
Let t = cost of a ticket
4*t
Cost 2
extra baggage fee
55
Add the costs together
4t+55
The Lagrangian,
has critical points where its partial derivatives vanish:
tells us 
, so that
Then with 
, we get
and 
tells us
Then there are two critical points, 
. The critical point with the negative 
-coordinates gives the maximum value, 
.
