<h3>Answer: Yes, it is a function</h3>

This is a function because there are no x values that repeat.

If we had repeated x values, then this would mean a certain input x leads to multiple outputs y, and that would not make it a function.

For instance, if we had (2,1) and (2,2) at the same time, then the input x = 2 leads to multiple outputs y = 1 and y = 2 at the same time. A function would not be possible in this example.

A function is only possible if any input x leads to exactly one output y. It is possible for y to repeat itself and still have a function.

Justin has 90 mild peppers and 36 hot peppers. If Justin wants to put the peppers into baskets so that each basket has the same
galina1969 [7]
There are only 36 hot peppers therefore to make it even “Justin” can only add 36 mild peppers. If he wants the greatest number of baskets than that too will be 18 (mini lol) baskets. Each basket can only contain 2 peppers to be even... 2/36 =18.

The expression 36 ÷ 6 · 2 + 1 is equal to _____. 4 18 2 13
Shtirlitz [24]

Answer:

13

Step-by-step explanation:

We have to use the BODMAS ( Bracket Of Division Multiplication Addition Subtraction) rule here

So first divide

36 ÷ 6 * 2 + 1

6 * 2 + 1

Now multiply

6 * 2 + 1

12 + 1

Now add

12 + 1 = <u>13</u>

An exterior angle of a regular polygon cannot have the measure Select one: a. 90 b. 120 c. 50 d. 40 e. 30
Otrada [13]

Answer:  c. 50

Step-by-step explanation:

1. By definition, when you add the exterior angles of a regular polygon, you obtain 360 degrees and the number of sides of that polygon can be calculated by dividing 360 degrees by the measure of the exterior angle of it.

2. As you know, the number of sides cannot be fractions, therefore, if you make the folllowing division:

360°/50°=36/5

You obtain a fraction.

3. Then, an exterior angle of a regular polygon cannot have the measure is 50°.

Which set of points does not represent a function
Maurinko [17]
If it is a bunch of dots on a graph, then the answer will be the one that has two sets of dots on the same vertical line (the y axis). so if there are two dots right above and below eachother, that graph is the correct answer.
