Which of the functions below is a linear function? y=x-7 y= 1 / - 7 y=x² - 7 y=1x1-7

y=x-7

Step-by-step explanation:

the rest are squared which means that they are parabolas. The last one has multiplication.

answer is c

step-by-step explanation:

81/12=324/x

x=48

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.
