If f(x) = x(power of 2)- 3x - 8
, find f(-6).

Step-by-step explanation:

f(x)= x²-3x-8

f(-6)= (-6)²-3(-6)-8

=36+18-8

= 46

okay i got you

x²-3x-8

now you replace every x with 6 and you have

(-6)²-3×(-6)-8

36+18-8

so f(-6)=46

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
