Find each key feature of the function shown in the graph.

in the xy graph the range of the x axis is negative 8 to 9 by increment of two. the range of the y axis is negative 8 to 8 by increment of two. on the graph there are open circles at the point (-8, 4) and (4.5, 2). there are closed points at (-4,-4) and (9.5, -2). all these points are joined by solid line.

range =

domain =

is the function positive or negative over the interval (–8, –6)?

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14

step-by-step explanation:

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
