Evaluate the function f(x)=6x-1 when x =0and when x=4

f(x)=6x-1   x=0                                  f(x)=6x-1    x=4

f(0)=6(0)-1                                            f(4)=6(4)-1

f(0)=0-1                                                 f(4)=24-1

f(0)= -1                                                   f(4)=23

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

answer: c.  

step-by-step explanation:

mixtures containing substances that get attracted to magnet can be separated using a magnet. we can separate iron from a mixture of sand and iron, as only iron attracts to the magnet.
