A system of equations is shown: 4x = −3y + 17 3x − 4y = −6 What is the solution to this system of equations? what lines are they, plz help

Step-by-step explanation:

Hello, we have two equations and two unknowns

(1) 4x = -3y + 17

(2) 3x - 4y = -6

We can solve them algebraically

for instance from (1) we can divide by 4 and then write

(1')

and then replace this expression of x in (2) it comes

and then

we can solve it graphically as well

we just need to graph the two lines and find the intersection point as shown below

hope this helps

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.
