DOES THIS SET OF ORDERED PAIRS
REPRESENT A FUNCTION?
{(2,4),(2,5), (2,6), (2,7) }

Answers

Answer 1
Answer:
No, this set of ordered pairs does not represent a function.

Explanation:
Functions have one y-value for a given x-value.

Ordered pairs are written (x, y).

In this set, when x=2, it has four y-values (4, 5, 6 and 7), so it cannot be a function.
Answer 2

Answer:

No

Step-by-step explanation:

No, this set of ordered pairs does not represent a function because functions  a relation in which each input has only one output.

Dinorah weighs 30.5 kg. Her dog weighs 6.1 kg. How many times as much does Dinorah weigh as her dog?

Answers

Answer:

5 times

Step-by-step explanation:

Given

[tex]D = 30.5kg[/tex] -- Dinorah's weight

[tex]d = 6.1kg[/tex] --- Her dog's weight

Required

Determine how much she weighs as much as her dog

To do this, we simply divide her weight by her dogs.

[tex]n = \frac{D}{d}[/tex]

[tex]n = \frac{30.5kg}{6.1kg}[/tex]

[tex]n = \frac{30.5}{6.1}[/tex]

[tex]n = 5[/tex]

NEED HELP THIS IS MY LAST QUESTION (WRONG ANSWERS GET BLOCKED)

The greatest number of bags she can make without having any stickers or pencils left over is 18 bags.

Step-by-step explanation:

The best way to go about this is by dividing the total number of pencils and stickers by the answer choices given and starting with the highest number (27). We already know that 27 goes into 54 twice without anything left over, but can only go into 36 once while having 9 leftover. This would eliminate 27 as an answer choice as it does not meet the criteria.

Repeat the same process with 18, so 54 divided by 18 is 3, and 36 divided by 18 is 2. There is nothing left over, every bag will have an equal number of pencils and stickers. With this answer, the question criteria is true, making this the correct answer choice.
