System of equations, variables, cost, tickets, adults, children.
For this case we must solve a system of equations with two variables represented by the tickets of students and adults of a school production.
We define the variables according to the given table:
- a: Number of tickets sold to adults
- c: Amount of tickets sold to children.
We then have the following system of equations:
From the first equation, we clear the value of the variable c:
Answer:
The value that could replace c in the table is:
Option C
Answer:
C= 67-A

Answer:
the parabola opens down
Step-by-step explanation:
Select the direction that this parabola opens.
y=-x^2/20
To find the direction of the parabola y=ax^2 +bx+c ,we need to consider the value of 'a'
If 'a' is positive then the parabola opens up
If 'a' is negative then the parabola opens down
from the given equation
The value of a=-1 which is negative
so the parabola opens down
x² 's coefficient is <0 ==> parabola opens down.

Answer: the first term is 5
Step-by-step explanation:
In a geometric sequence, the consecutive terms differ by a common ratio. The formula for determining the sum of n terms, Sn of a geometric sequence is expressed as
Sn = (ar^n - 1)/(r - 1)
Where
n represents the number of term in the sequence.
a represents the first term in the sequence.
r represents the common ratio.
From the information given,
S12 = 20475
r = 2
n = 12
Therefore,
20475 = (a × 2^(12) - 1)/2 - 1
20475 = (a × 4095)
20475 = 4095a
a = 20475/4095
a = 5
