The telephone company offers two billing plans for local calls. plan 1 chargers $26 per month for unlimited calls and plan 2 charges $19 per month plus $0.04 per call. a) use an inequality to find the number of monthly calls for which plan 1 is more economical than plan 2
b) explain the meaning of the answer to part a

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

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.

i think it might be a but you might want a second opinion

answer: you need to organize this better it does not make sense.
