Step-by-step explanation:

Relations vs Functions

For a given relation between two variables x and y to be a function, it must meet the following condition: every value of x must be related to one and only one value of y.

When the graph of a relation is given, we can easily tell the difference by using the vertical line test as follows:

Imagine a vertical line moving through the x-axis. If any line touches the graph of the relation at more than one point, then the relation is not a function.

If we place vertical lines through the x-axis, they would touch the function twice at some values of x.

Thus, the graph is not a function

A ticket service is selling tickets to a concert. An order of 4 tickets has a price of $63 and an order of 6 tickets has a price

Valentin [98]

Answer:

x = Number of tickets for the concert

y = Price of the order of x tickets

y = 14.5x + 5

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Order of 4 tickets has a price of $63

Order of 6 tickets has a price of $92

2. Write an equation to find the price of any amount of tickets.

Let's find out the price of a ticket to understand if there's a service fee and how much is it, this way:

Price of a ticket = (Order of 6 tickets - Order of 4 tickets)/2

Price of a ticket = (92 - 63)/2

Price of a ticket = 29/2 = 14.50

If a ticket costs $ 14.50, 4 tickets will cost $ 58 and 6 tickets will cost $ 87, therefore there is a service or delivery fee of $ 5.

Order of 4 tickets - Price of 4 tickets = Service or delivery fee

Replacing, we have:

63 - 58 = 5

Order of 6 tickets - Price of 6 tickets = Service or delivery fee

Replacing, we have:

92 - 87 = 5

Now, we can write the equation to find the price of an order of any amount of tickets, this way:

x = Number of tickets for the concert

y = Price of the order of x tickets

y = 14.5x + 5

Louann and Carla received equal scores on a test made up of multiple choice questions and an essay. Louann got 14 multiple choic

HACTEHA [7]

Hello,

x= number of points for each multiple choice question correct
L= Louann's score
C= Carla's score

Louann got 14 multiple choice questions correct and 24 points for her essay, so:

$L=14*x+24$

Carla got 16 multiple choice questions correct and 14 points for her essay, so:

$C=16*x+14$

But we know that they got the same score, then:

$L=C \\ 14x+24=16x+14 \\ 10=2x \\ \boxed{x=5}$

Answer: Each multiple choice question was 5 points
