What is the solution set of 4x = y and 2x2 − y = 0?

(2,8)

Step-by-step explanation:

4x = y equ1

2x^2 - y =0 equ2

y = 4x

substitute the value of y into equ 2

Then we have; 2x^2 - 4x = 0

2x (x - 2) = 0

2x = 0

x = 0/2 = 0

x - 2 = 0

x = 2.

then put the values of x in equ 1...

y = 4x

y = 4(0)

y = 0

y = 4x

y = 4(2)

y = 8

i.e (2,8)

I 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.
