Are the lines y = –x – 6 and 4x – 4y = 12 perpendicular? explain. a.no; their slopes are not equalb. yes; their slopes have product –1.c. no; their slopes are not opposite reciprocals. d.yes; their slopes are equal.

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
