Acollege is selling tickets for a winter fund-raiser. one day, krissa sold 14 adult tickets and 8 student tickets for a total of $376. the next day, she sold 7 adult tickets and 11 student tickets for a total of $272. krissa wanted to find the price of one adult ticket, a, and the price of one student ticket, s. she wrote and solved the following system of equations.

Step-by-step explanation:

Let's solve this by elimination, then substitution.

x= Adult ticket

y= Student ticket

First day: 14x + 8y = 376

Second day: 7x + 11y = 272:

14x+8y=376

7x+11y=272

Divide 14x+8y=376 by -2:

-7x+-4y=-188

7x+11y=272

Eliminate both -7x and 7x:

-4y=-188

11y=272:

Add all numbers:

7y=84

Divide both sides by 7/ divide 84 by 7:

y=12

Now substitute y into one of the equations:

7x+11y=272:

7x+11(12)=272

Simplify:

7x+132=272

Subtract both sides by 132:

7x=140

Divide both sides by 7 (140/7):

x=20

Adult Tickets: $20

Student Tickets: $12

let f (x ) is a function and c be a positive real number,   the graph of the function g (x ) = f (cx ) is represented as follows.

when, c > 1,   the function compresses it in the x - direction.

when, 0 < c < 1, the function stretches it.

the function is g ( x ) = (9x )2.

the heighest power of x in g ( x ) = (9x )2 is 2, so the parent function is square function.

the equation of parent function is f ( x ) = x 2 .

the function is g ( x ) = (9x )2 and the parent function is f ( x ) = x 2 .

so, the functions f and g have the following relationship.

g ( x ) = f ( 9x ).

compare the function g ( x ) = f ( 9x ) with g (x ) = f (cx ).

c = 9 ( > 1 ).

so, the function g (x ) = (9x )2 compresses it in the x - direction.
