At the movie theatre, child admission is $6.00 and adult admission is $9.90 . On Saturday, 155 tickets were sold for a total sal
Leviafan [203]
57 children tickets were sold on Saturday.

You could set this up as a system of equations.
x + y = 155
6.00x + 9.90y = 1312.20

First step is multiplying the first equation by -6 to use the elimination method.

-6.00x + -6.00y = -930
6.00x + 9.90y = 1312.20

The positive and negative 6x cancel out until you are only left with the y.

Combining them would make your equation...
3.9y = 382.2

Next you would divide by 3.9 on both sides to get the y by itself.

The result of that would be y = 98. Which means 98 adult tickets were sold. Then you would plug y into either of the equations to solve for x.

Two exponential functions are shown in the table. A 3-column table has 5 rows. The first column is labeled x with entries 2, 1,
DanielleElmas [232]

Answer:

B. The functions f(x) and g(x) are reflections over the y-axis.

Step-by-step explanation:

From the information given the table appears as;

x            f(x)=2^x              g(x)=0.5^x

2               4                            0.25

1                 2                           0.5

0                1                             1

-1                0.5                         2

-2               0.25                       4

Plotting the two graphs to view the trends;

In the graph of f(x)=2^x against x you notice a curve with increasing positive slope.

In the graph of g(x)=0.5^x against x you notice a curve with a negative slope that is increasing.

In combining both graphs you notice that f(x) and g(x) are reflections over the y-axis.

Correct answer is ;The functions f(x) and g(x) are reflections over the y-axis.
