solve X -6x+9=0. by graphing

a. x=-3
b. x=3
c. x=-1
d. x=1

The answer is d

Step-by-step explanation:

Standard Form : -6x + 9= 0

Factorization: -3(2x -3) =0

Solution: x= 9/6=1.5

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

the answer

b. they are parallel and will never intersect.
