Which is a point of the vertices for the following:

y≥3x−5
y≤−12x+2
x≥−4

a. (-4, -20)
b. (-4, -15)
c. (-4, -4)
d. (-4, 4)

i don't know you should ask someone who does

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
