Julia has made 9 posts while trying out a new social media platform. Starting now, she plans to make 1 post daily.

Question

Write an equation that shows how the total number of posts, y, depends on the number of elapsed days, x.
y=

Answer 1

To represent the total number of posts, \( y \), as a function of the number of elapsed days, \( x \), we can use the following equation:

\[ y = 9 + x \]

In this equation:

• \( 9 \) represents the initial number of posts Julia has made.
• \( x \) represents the number of days that have elapsed since she started posting daily.

Therefore, for each day that passes (each increment in \( x \)), the total number of posts \( y \) increases by 1.
