Given △ABC with vertices: A(−1, 7), B(−4, 2), C(−3, 1). Reflect △ABC across the line y = −2 to create image △A'B'C'. Reflect △A'B'C' across the line x = 2 to create image △A″B″C″. What are the coordinates of the vertices of △A″B″C″? What single transformation would take △ABC onto △A″B″C″?

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
