<h3>Answer:  D) 6</h3>

======================================================

Explanation:

Direct proportion equations are in the form y = kx, for some constant k.

The k value is the constant of proportionality. Solving for k leads to k = y/x.

For each row in the table, divide the y value over the paired x value.

  • Row1:  k = y/x = 12/2 = 6
  • Row2:  k = y/x = 24/4 = 6
  • Row3:  k = y/x = 30/5 = 6
  • Row4:  k = y/x = 54/9 = 6

Each row leads to the same k value, so the constant of proportionality is 6.

The equation y = kx updates to y = 6x.

This line has slope 6 and y intercept 0.

All direct proportion equations go through the origin.

The algebraic form of an arithmetic sequence is 5n-2<br>a) What is its common difference?​
Alexxandr [17]

Answer:

5

Step-by-step explanation:

[math]

U_{n} = 5n - 2 \\

Common Difference = U_{n+1} - U_{n} \\

= [5(n + 1) - 2] - [5n - 2] = [5n + 5 - 2] - [5n - 2]\\

= 5n + 5 - 2 - 5n + 2\\

= 5
