Consider the function represented by 9x + 3y = 12 with x as the independent variable. How can this function be written using function notation?

Its 12 U^U

Step-by-step explanation:

subtract 9x from each side

3y = 12 - 9x

divide by 3

y = 4-3x

f(x) = 4-3x

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.
