A system of equations is shown below. Which of the following replacements can be made to produce the same (x, y) solution?
2x - y=4
3x + 2y = 1
A) Replace 2x - y = 4 with 8x - 4y = 4.
B) Replace 3x + 2y = 1 with 5x + y = 5.
C) Replace 3x + 2y = 1 with 6x + 2y = 2
D) Replace 2x - y = 4 with 3x + 2y = 1

2 5/8 is the final answer! : )

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

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.
