Answer:

1/3, 3, -1/3

Step-by-step explanation:

A rational number is a number that can be expressed with a fraction. In this case we have:

1/3 , 3 (all natural numbers are also rational: in fact for example 3 can be expressed with the fraction: 3/1) , -1/3

333/0 is not a rational number because the division is impossible

√3 is not rational because can’t be expressed with a fraction

Helpppppp plsssssssss
WINSTONCH [101]

Answer:

Option D <em>The pattern is multiplicative because the earnings are 12 times the number of hours worked in each pair of values </em>is correct option.

Step-by-step explanation:

At x-axis we have number of hours worked and y-axis represents earnings in dollars.

We can make the table:

Number of hours worked (x)         earnings in dollars (y)

1                                                                12

2                                                               24

3                                                               36  

4                                                               48

5                                                                60

Now, we need to find the pattern.

If we add 1+ 11 we get 12, but if we add 2+ 11 we get 13 and not 24 so, the pattern is not additive.

Now, if we multiply 1 by 12 (1 x 12) we get 12,

then 2 x 12 = 24

3 x 12 = 36

4 x 12 = 48

and 5 x 12 = 60

The same number if multiplied with x-axis we get y-axis.

So, the pattern is multiplicative. and we are multiplying 12 with the number of hours worked, so the correct option is option D.

Option D <em>The pattern is multiplicative because the earnings are 12 times the number of hours worked in each pair of values </em>is correct option.
