The function f(x)=0.12x+11.9 can be used to predict diamond production. For this function, x is the number years after 2000, and f(x) is the value (in billion of dollars) of year's diamond production. Use this function to predict diamond production in 2015

answer: b

step-by-step explanation:

the weight of the object inside the box!

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
