Express the set of the numbers x satisfying condition |4x−1|≤4 as an interval. (Use symbolic notation and fractions where needed. Give your answers as intervals in the form (∗,∗). Use the appropriate type of parenthesis "(", ")", "[", or "]" depending on whether the interval is open or closed.)

it would be 6xy and -16xy.

both equations and proportions are better.

step-by-step explanation:

b and c

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.
