Write an equation of the parabola in vertex form that passes through (−7, −15) and has vertex (−5, 9).

i think it's b

step-by-step explanation:

because the graph is 2 above (0,0)

step-by-step explanation:

10.50 + taxes which added up to 11.50

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.
