What are the first twenty counting numbers in base nine?

In base 9, you count the same way as in base 10, except you skip everything with a 9. So you would have the numbers 0-8 like normal, and them move on to 10. Then you write 11-18, and move on to 20. Continue until you hit twenty numbers.

Hey bby was a good way i just got

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
