Answer:
Equation of the axis of symmetry is: x = 3
Step-by-step explanation:
The equation

is the equation of a parabola, of the form
whose vertex is located at the x-coordinate:

Then, for our case the x position of the given parabola, is:

Then the equation of the axis of symmetry, which is a vertical line that goes through the vertex, would be given by:
x = 3
The answer to your question is 17/18
Answer:
Per child admission costs $8.5
Per Adult admission costs $13.5
Step-by-step explanation:
Let x be the amount of admission per child and y be the amount of admission per adult
For Tom's party:
13x+2y=137.50 (Equation 1)
For Lisa's Party:
9x+2y=105.50 (Equation 2)
Using Elimination Method:
Add Equation 1 & 2
13x+2y=137.50
9x+2y=105.50
- - = - (Change of Signs)
---------------------------------
4x+0y=34.00
x=34/4
x=8.5
Putting the value of x in Equation 2
13(8.5)+2y=137.50
110.5+2y=137.50
2y=137.50-110.50
2y=27
y=27/2
y=13.5
1500 divided by 100 is 15 .
