Noah and Lin are each trying to solve the equation x2 - 6x + 10 = 0. They know that the solutions to 3? = -1 are i and-i, but they are not sure how to use this information to solve for z in their equation.
Lin decides to solve the equation using the quadratic formula. Here is her work:
2
-DIVb2-4ac
20
-(-6)/(-6)2-4(1)(10)
2(1)
6+436-40
x
2
Lin knows 36 - 40 is a negative number and isn't sure what to do next. Show how Lin can write her solution
using i

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

x + 4/7
