If y varies directly as x, and y is 48 when x is 6, which expression can be used to find the value of y when x is 2?

Answer

Find out the find the value of y when x is 2 .

To prove

As given

If y varies directly as x .

y = kx

Where  k is the constant of proportionality.

y is 48 when x is 6,

48 = 6k

k = 8

Now calculate the value of y when x is 2 .

y = 8 × 2

y = 16

Therefore the  value of y is 16  when x is 2 .

look at the picture i have filled out a table for it. hope this .

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.
