Solve the inequality

4+4x< 16

x<3

Step-by-step explanation:

4+4x<16

4x<16-4

4x<12

x<12/4

x<3

x< 3

Step-by-step explanation:

4+4x< 16

4x< 16-4

4x< 12

x< 3

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

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
