Answer:

The proportional table in the attached figure

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form k=\frac{y}{x} or y=kx

In a proportional relationship the constant of proportionality k is equal to the slope m of the line <u><em>and the line passes through the origin</em></u>

<em>Verify each table</em>

Find the value of the constant of proportionality k for each ordered pair of a table.

k=\frac{y}{x}

If all the values of k are the same, then the table represent a proportional relationship between x and y

Table 1

For x=1, y=2 ----> k=\frac{2}{1}=2

For x=2, y=4 ----> k=\frac{4}{2}=2

For x=3, y=8 ----> k=\frac{8}{3}=2.7

The values of k are not equal

so

This table not represent a proportional relationship between x and y

Table 2

For x=0, y=4

The line not passes through the origin

so

This table not represent a proportional relationship between x and y

Table 3

For x=0, y=0 ----> is OK the line passes though the origin

For x=1, y=1 ----> k=\frac{1}{1}=1

For x=2, y=4 ----> k=\frac{4}{2}=2

The values of k are not equal

so

This table not represent a proportional relationship between x and y

Table 4

For x=1, y=4 ----> k=\frac{4}{1}=4

For x=2, y=8 ----> k=\frac{8}{2}=4

For x=3, y=12 ----> k=\frac{12}{3}=4

The values of k are the same

so

This table represent a proportional relationship between x and y

Stella [2.4K]

Answer:

Jen saved $320.

Step-by-step explanation:

Since she would like 8 bushes total and 1 = $60, we will multiply (60 x 8) to get a total of $480.

Finally, to find out how much Jen saved, we must subtract Jens final priced total ($480) - the landscapers asking price ($800) to get ( = $320)

Jen payed $480 and saved $320.

Hope this helps...
