Which table of ordered pairs represents a proportional relationship?
dedylja [7]

Answer:

A 2-column table with 3 rows. Column 1 is labeled x with entries 14, 28, 42. Column 2 is labeled y with entries 2, 4, 6.

Step-by-step explanation:

Examining the response options:

A 2- compartment chart with 3 rows. Column 1 is designated x with records 1, 5, 6. compartment 2 is designated y with records 5, 20, 30.

No, as y = 25 not 20 and x = 5 .

A 2- compartment chart with 3 rows. Column 1 is identified x with approaches 48, 32, 16. compartment 2 is designated y with listings 4, 2, 1.

No, y =64 not 48 and x= 4.

A 2- compartment chart with 3 lines. compartment 1 is designated x with records 0, 1, 3. compartment 2 is designated y with records 90, 70, 25.

No, y= 25+3*45= 160 not 90 and x = 3.

A 2- compartment chart with 3 lines. compartment 1 is designated x with records 42, 28, 14. compartment 2 is designated y with records 2, 4, 6.

Yes, as 2*7 = 14, 4*7= 28, 6*7= 42.

Answer:

The answer to your question is the third option

Step-by-step explanation:

a)               0.023x³ + 0.4x² - 2.1x + 8.3

                 0.023(2)³ + 0.4(2)² - 2.1(2) + 8.3

                 0.023(8) + 0.4(4) - 2.1(2) + 8.3

                 0.184 + 1.6 - 4.2 + 8.3

                 10.084 - 4.2

                 5.884

b)              0.023(4)³ + 0.4(4)² - 2.1(4) + 8.3          

                 0.023(64) + 0.4(16) - 8.4 + 8.3

                 1.472 + 6.4 - 8.4 + 8.3

                 16.172 - 8.4

                7.772
