Hi There!

The number of teams who entered in a 3-on-3 charity basketball tournament can be modeled by function T, where x is the number of years since the tournament first started.

T(x)=4x+24

The entire fee paid by each team to enter the tournament can be modelfied by function F, where x is the number of years since the tournament first started.

F(x)=5x+45

Which function,R, best represented the total entry fees collected in the xth year since the tournament first started?

Answer - D. R(x)=9x+69

Option D makes the most sense for the following question because since whatever x is multipled by the number thats just added so you just combine like terms and do 24 + 45 = 69.

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
