Answer:
The system of equation to model the situation are:
C = 10t + 8
C = 12t
Step-by-step explanation: Complete question ( Let C be the total cost and let t be the number of tickets).
Ordering tickets online cost $10 plus additional service charge of $8.
Therefore total cost,C = 10t + 8
Buying tickets at the door cost $12
Therefore, total cost,C = 12t
The system of equation to model the situation are:
C = 10t + 8
C = 12t
Answer:

Step-by-step explanation:
The given function is
.
The domain refers to all values of x for which this function is defined.
Recall that: the domain of
is 
And we know
is the reciprocal of
.
Therefore the complement of the domain of
which is
is the domain of 
Answer:
x=√-1/3 y^2 +3 or x=-√-1/3 y^2 +3
Step-by-step explanation:
Let's solve for x.
3x2+y2=9
Step 1: Add -y^2 to both sides.
3x2+y2+−y2=9+−y2
3x2=−y2+9
Step 2: Divide both sides by 3.
3x^2/3= -y^2+9/3
x^2=-1/3 y^2 +3
x=√-1/3 y^2 +3 or x=-√-1/3 y^2 +3
Hope it helped!
