The percent of the jerseys :
6 : 800 = 0,75%
since we don't know any of your vocabulary, I might not be using the ones you learned
since we have points A and B and points F(A) and F(B), I think they want us to use the word 'translation'
"The function F(x) translates each point to the right without moving them up or down." would be my description
also the 2 lines are paralell
you find what they both divide by and then divide each one and then you keep doing that until you cant no more
39, it is like the fibonacci sequence you take the 2 previous numbers and add them together to get the next number.
50+20=70
Have a great day:)
