Dominique buys $14.95 worth of gasoline for her car. if the gas station charges $1.43 per gallon, how many gallons did she get? round to the nearest tenth.

I'm going to represent this situation as an equation:

x = the number of gallons

y = the total cost

1.42x = y

1.42x = 14.95

[They charge $1.43 per gallon(x), and she payed a total (y) of $14.95]

You need to find the number of gallons or "x".

To do so, you isolate "x" in the equation:

1.42x = 14.95     Divide 1.42 on both sides (or divide 14.95 by 1.42)

x = 10.5    She got 10.5 gallons

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

the answer is. -82562234434584
