How can i be math teacher when i grow up?

Answers

Well... you would have to start studying really hard in 7th grade and make sure you keep getting straight As. Behavior is important too. Then... you would have to get into a college where you can major in math... so yeah. Good luck if you plan on doing this! 
If you want to be a math teacher, first of all, you should be able to do math problems with no trouble at all, the problems will depend on what level you are going to teach.You must also be able to explain each and every step with patience because being a teacher can be stressful due to the lack of intelligence of some students.

Right △ABC has coordinates A(-7, 3), B(-7, 10), and C(-1, 3). The triangle is reflected over the x-axis and then reflected again over the y-axis to create △A'B'C'. Which are the coordinates of vertex A'?

Answers

X-axis = A (-7,-3) B (-7,-10) C (-1,-3) first they changed to the x-axis which is this. Just so you know on the x-axis the x-axis stay and the y-axis changed which is this.
When they reflect again on the y-axis the verter of A' is
A' (7, 3) = answer
On the y-axis the y- axis doesnt change but the x-axis changed.
Hope this help!

the answer is... (7,3)
