Can someone help me I can’t get it right.

Answer

the numbers in the x column equal x. So you have to put them numbers in replacement of x. For example, the x=1 would be 1²-(4 ×1) so it would be -3. Sorry if this doesnt make sense but thats how I would do it!

Step-by-step explanation:

-1,5 0,0 1,-3 2,-4 3,-3 4,0

Step-by-step explanation:

Formula

y= ()^2-4()

plug in the x to the parenthesis in order to get y

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

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent
