Consider the function f(x)=x^2-5. if g(x)=f(x-7), what can be said of g(x)? choose all that apply:

-the graph of g(x) is shifted seven units to the left of f(x).

-the graph of g(x) is shifted seven units to the right of f(x).

-the graph of g(x) is shifted seven units above f(x).

-the graph of g(x) is shifted seven units below f(x).

-the vertex of g(x) is (7,20).

-the axis of symmetry of g(x) is x=7.

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
