The table shows the distance in feet, y, that a rocket traveled in x seconds.
Murrr4er [49]

Answer:

The correct option is D. y = 25x^{2}.

Step-by-step explanation:

i) From the table and our own observation and a trial and error approach we

  can clearly see that the equation that matches y in feet ( the distance

  traveled by the rocket) and x in seconds ( the time elapsed) is given by the

  equation y = 25x^{2}

 Therefore the correct option is D. y = 25x^{2}.

The ratio of Victors money to Susies money is 4:7 at first. After Victor spent half of his money and Susie spent $60, Susie had
valkas [14]

Answer:

Victor originally had $80

Step-by-step explanation:

Let Victor have $4x

Let Susie have $7x

Since Victor spent half his money, he now has $2x

Susie spent $60 and thus now has $(7x - 60)

The final ratio of Victor's money to Susie's money is therefore  2x : $(7x - 60). This is given 1:2. Now we just need to solve the proportion by cross-multiplying

2x : (7x - 60) = 1:2

1 × (7x - 60) = 2 × 2x

7x - 60 = 4x

3x = 60

x = 20

Therefore Victor originally had $4x = $80.
