15. Which of the following equations has a graph that crosses the y-axis at a point lower than the graph of y=-2x^2-1?

A. y=-3x^2+3

B. y=-3x^2+1

C. y=3x^2-3

D. y=-3x^2-1

C. y=3x^2-3

Step-by-step explanation:

y=3x^2-3 is lower than y=2x^2-1

So C.y=3x^2-3

The answer would be : C. -3x^2-3.

Hope this helps !

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
