30

Step-by-step explanation:

120 divided by 30 is 4, and 150 divided by 30 is 5.

2. Expert says:

the range of a function is the range of y-values for which it is defined, or exists. given that we are only looking at the y-values, we can already discount the first two answers as they deal with the domain of the function (range of x-values).

now, what we need to do is find the smallest and highest y-values for which the function is defined. if you'd like, you could take a ruler and start at the very bottom of the graph, find the lowest point, then move the ruler higher and higher until you reach the highest point. doing so either in your head or with an actual ruler, we can see that the lowest y-value is -5 and the highest y-value is -1.

the question now remains as to whether they are included in the range (fourth answer) or excluded (third answer). the key here is to recognise whether they are marked with an open or a closed circle. since both (-2, -5) and (2, -1) are marked with a closed circle, they are points that exist on the graph and are thus included in the range (note that if they were marked with an open circle like (4, -2) then that would signify that there is a break in the graph at that point).

thus, the fourth answer, (y | -5 ≤ y ≤ -1), is correct.

also note that usually it is good practice to scan your eye inbetween the highest and lowest point for any breaks in the graph - we do have one here at (4, -2), however -2 is still included in the range because there is another point that is included in the graph with the same y-value, ie. point (1, -2).

i hope that but if you require any further explanation don't hesitate to comment below.

$Me if you can and if you finished this lesson on edg- comment you.$

28/12 = 12*2+4
12/4 =3

Therefore the hightest common factor of 12 and 28 is 4.

Hope this helps !

0

Step-by-step explanation:

The Highest common factor is the highest number that can divide all the numbers at once.

-12

4

it is 0 because -12 has a negative so I can divide 4

30

Step-by-step explanation:

The factors of 120 are: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120

The factors of 150 are: 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 150

Then the greatest common factor is 30.

11. jstringe424 says:

What is the greatest common factor of 120 and 150? The greatest common factor of 120 and 150 is 30, because 30 is the highest number that is divisible by both numbers.

12. lorrainetakai1738 says:

1

Step-by-step explanation:

1 is the only common factor they have between the two numbers.

Hope i helped have a great day!
