Help fast!! Choose the number line that represents the fraction equivalent to three-twelfths. A number line with zero, one twelfth, two twelfths, three twelfths, four twelfths, five twelfths, six twelfths, seven twelfths, eight twelfths, nine twelfths, ten twelfths, eleven twelfths, and one marked on it. A red line is drawn from the zero tick mark to the three twelfths tick mark.
Question 5 options:

A number line with zero, one eighth, two eighths, three eighths, four eighths, five eighths, six eighths, seven eighths, and one marked on it. A red line is drawn from the zero tick mark to the three eighths tick mark.

A number line with zero, one fourth, two fourths, three fourths, and one marked on it. A red line is drawn from the zero tick mark to the one fourth tick mark.

A number line with zero, one fifth, two fifths, three fifths, four fifths, and one marked on it. A red line is drawn from the zero tick mark to the one fifth tick mark.

A number line with zero, one sixth, two sixths, three sixths, four sixths, five sixths, and one marked on it. A red line is drawn from the zero tick mark to the one sixth tick mark.

1/4

Step-by-step explanation:

Multiply one times three, and four by three. It will equal to three out of twelve or 3/12. ( hope this helps)

when functions are first introduced, you will probably have some simplistic "functions" and relations to deal with, usually being just sets of points. these won't be terribly useful or interesting functions and relations, but your text wants you to get the idea of what the domain and range of a function are. small sets of points are generally the simplest sorts of relations, so your book starts with those.

step-by-step explanation:

state the domain and range of the following relation. is the relation a function?

{(2, –3), (4, 6), (3, –1), (6, 6), (2, 3)}

the above list of points, being a relationship between certain x's and certain y's, is a relation. the domain is all the x-values, and the range is all the y-values. to give the domain and the range, i just list the values without duplication:

domain: {2, 3, 4, 6}

range: {–3, –1, 3, 6}

(it is customary to list these values in numerical order, but it is not required. sets are called "unordered lists", so you can list the numbers in any order you feel like. just don't duplicate: technically, repetitions are okay in sets, but most instructors would count off for this.)

while the given set does indeed represent a relation (because x's and y's are being related to each other), the set they gave me contains two points with the same x-value: (2, –3) and (2, 3). since x = 2 gives me two possible destinations (that is, two possible y-values), then this relation is not a function.

note that all i had to do to check whether the relation was a function was to look for duplicate x-values. if you find any duplicate x-values, then the different y-values mean that you do not have a function. remember: for a relation to be a function, each x-value has to go to one, and only one, y-value.

state the domain and range of the following relation. is the relation a function?

{(–3, 5), (–2, 5), (–1, 5), (0, 5), (1, 5), (2, 5)}

i'll just list the x-values for the domain and the y-values for the range:
