Answer:
Not a function
Step-by-step explanation:
To answer this, we first need to know what a function actually is: A function is a relation between 2 sets which relates the element of the first set to only one element of the second set.
We can see in the provided image that the value -9 is related to 2 values of the second set, hence it is NOT a set.
Another way to think about it is that a function takes an input and gives only one output (where the left set is the input and the right set is the output). Since -9 gives 2 outputs from the given relation, it cannot be a function.

How much should a customer expect to pay for a one-night stay if they are a member of the hotel's loyalty club and make
their reservation over the phone?
Answers
Answer:
$114.32
Step-by-step explanation:
Original Price: $132.52
increased: $34.65
Loyalty Club: -$57.80
Phone Fee: $4.95
You add all of them together, except for the Loyalty Club Fee. You subtract that fee by the total.
The amount of pay for a one-night stay, if they are a member of the hotel's loyalty club and make their reservation over the phone, will be $113.77
What will be the amount?The average cost of a one-night stay at a hotel was $132.52. Since then, the hotel has changed ownership, and several changes have been made to the cost of staying at the hotel. Last summer, the new owners adjusted room prices so that the average cost of a one-night stay increased by $34.65.
Last December, the new owners offered a $57.80 per night discount to guests who belong to their loyalty club. Last week, the new owners introduced a service fee of $4.95 for any reservation made over the phone.
The price will be calculated as:-
Original Price: $132.52
increased: $34.65
Loyalty Club : - $57.80
Phone Fee: $4.95
You add all of them together, except for the Loyalty Club Fee. You subtract that fee by the total.
= 132.52 + 34.65 + 4.95 - 57.80 = $113.77
Therefore the amount of pay for a one-night stay, if they are a member of the hotel's loyalty club and make their reservation over the phone, will be $113.77.

Step-by-step explanation:
The computation of the distance travelled is shown below:
Total distance would be
[tex]= 52 \frac{4}{ 5} + 14 \frac{ 4}{5}\\\\= \frac{264}{5} + \frac{74}{5}\\\\= \frac{338}{5}[/tex]
Now if the same route would taken again in order to back home

Suzanne, Latisha, and Morgan measure their heights. Suzanna is 0.8 times the height of Latisha, and Morgan is 1.09 times the height of Latisha. Who is the tallest? Who is the shortest?
Answers
Answer:
Tallest = Morgan
Shortest = Suzanna
Step-by-step explanation:
Assuming Latisha = 1
0.8 is less than 1, meaning it's 80% the height of Latisha, so this means Suzanna is shorter than Latisha.
1.09 is more than 1, Morgan is taller than Latisha.
Morgan is tallest and Suzanna is shortest, Latisha in the middle.

Find the solution of the system of equations.
−x−3y= −3
x−6y= −24
Answers
Answer:
(-6 , 3)
Step-by-step explanation:
-x-3y= -3
x-6y= -24
1. solve each eq so they make x=___
-x = -3 + 3y
x= 3 - 3y
and
x = -24 + 6y
2. set = to each other and solve for y
3 - 3y = -24 + 6y
27 = 9y
y = 3
3. plug the y value into one of the x=__ eq's and solve for x
x = 3 - 3y
x = 3 - 3(3)
x = 3 - 9
x = - 6
your solution is ( -6 , 3 )
