I NEED HELP I ONLY HAVE 1 MORE HOUR TO FINISH THIS, Which expression(s) could you use to find out the total cost for the three students?

Kadie is correct

Step-by-step explanation:

There are 3 people (including Kadie). Kadie said that you can write the expression by multiplying 3 by all of the admissions and fees for the three things they did at the dance. By doing this and adding up the result, you get the money that needs to be paid at the dance for all three of them.

Hope this helps!

a is 8.b is 10.c is 10.5. d is -.5

step-by-step explanation:

just minus the smallest number from the biggest.

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.
