Does anyone know how to do this? !

B, C

Step-by-step explanation:

I am sure you have heard of the vertical line test. What the vertical line test does is make sure, for every, input, there is only one output. What this means is that two points cannot have the same x, unless they have the same y.

Two different x's can have the same y, but two different y's cannot have the same x.

In this problem, the x's that are taken by other coordinates with different y values are: 1, 3, 4, -4.

This means that the x you are trying to find cannot be any of those since the y value is different than all the other points. Which leaves you with the answers B and C.

Hope this helps, don't hesitate to ask more questions.

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

i believe the correct answer is b.
