Answer:
The inequality to determine how many more players can make the team is:

On solving it we get :

Thus, the number of players that can still make in the team must be no more than 9.
Explanation:
Given:
Maximum number of players the soccer team can have = 26
Number of players already chosen by coach = 17
To find how many players can still make the team.
Solution:
Let the players that can still make the team be =

Players already chosen = 17
Total number of players in the team can be given as =

Total numbers must not exceed 26.
So, the inequality can be written as:

Solving for

Subtracting both sides by 17.

∴

Therefore, no more than 9 players can still make in the soccer team.
