what equation represents the proportional relationship displayed in the table?
x | 2 4 6 8 y 10 20 30 40

Enter your answer in the box to complete the equation.
y = (blank) x

y=5x

Step-by-step explanation:

The table is given as:

x       |       y

2       |        10

4       |         20

6       |         30

8       |          40

A proportional relation satisfy the relation:

We can substitute any x value with the corresponding y-value and solve for k.

When x=2,y=10

This implies that:

Divide both sides by 2 to get:

Hence the equation is

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you
