Which is equivalent to 4x/x-7 - x+7/x
spin [16.1K]

Answer:

The answer to your question is the second choice

Step-by-step explanation:

                        4x/ (x - 7)  -  (x +7) / x

- Find the greatest common factor from x and (x - 7)

                 GCF = x(x - 7)

- Substract the terms

                     [4x(x) - (x + 7)(x - 7)] / x(x - 7)

- Simplify

                     [ 4x² - x² + 49] / x(x - 7)

                     [ 3x² + 49] / x(x - 7)

- Result

                      3x² + 49  /  x(x - 7)

Which relationships could have a negative correlation? Select three options.
Rudik [331]

The relationships that could have a negative correlation are as follows:

  • the speed of a train and the length of time to reach the destination
  • number of hours worked and free time
  • speed of a car and minimum stopping distance

<h3>What is negative correlation?</h3>

Correlation between two variables shows the relationship between the two variables.

A positive correlation means that both variables move in the same direction i.e. as one increases, the other increases.

However, a negative correlation means that both variables are inversely related i.e. one increases as the other decreases.

Therefore, the relationships that could have a negative correlation i.e. inversely related are as follows:

  1. the speed of a train and the length of time to reach the destination
  2. number of hours worked and free time
  3. speed of a car and minimum stopping distance
