Answer:
Number of Adults Ticket=393
Number Of Students Tickets=792
Step-by-step explanation:
Let 'x' be the Adult's tickets
Let 'y' be the Student's tickets
x+y=1185 (total sold tickets)
5x+y=2757(total cost of tickets)
-(5x+y=2757)x+y=1185
(-5x-y)- x+y=1185-2757
=-4x+0 = (-1572)
=-4x=(-1572)
x= (-1572)÷-4
=393
=x+y=1185
=393+y=1185
=y=792
So Number of Adults Ticket=393
Number Of Students Tickets=792

Answer:
-0.16
Step-by-step explanation:
The 'a' value can be found by looking at the difference between the y-value of a point 1 unit from the vertex, and the y-value of the vertex.
Here, that is a negative fraction of a unit. If we assume the value is a rational number that can be accurately determined from this graph, then we can find it by looking for a point where the graph crosses a grid intersection. It looks like such grid points are (-7, 0) and (3, 0). The vertex is apparently (-2, 4), so the vertex form of the equation is ...
y = a(x +2)^2 +4
Using the point (3, 0), we have ...
0 = a(3 +2)^2 +4 . . . . . fill in the values of x and y
-4 = 25a . . . . . . . . . . subtract 4; next, divide by 25
a = -4/25 = -0.16
I am guessing that the correct form of equation
is:
f(x)
= 16,800(0.9)^x
where
x is the exponent of (0.9)
Since
we are looking for the original population and x stand sfor the number of years,
therefore x=0
substituting:
f(x) = 16,800(0.9)^0
Since (0.9)^0 would just be equal to 1. Therefore
the original population is
16,800.
Answer: B. 16,800
