Which expression is equivalent to the expression shown!

D

Step-by-step explanation:

Given

- ( - x + 6x + 1) - 3x ← distribute parenthesis

= x - 3x - - 3x

=   x - 6x -

= x - x -

= - x -

= - 5 x - → D

< xcy ≅ < xby

step-by-step explanation:

in δcax and δbax,

so, δcax ≅ δbax (side-angle-side or sas)

since δcax ≅ δbax, we can conclude < acx ≅ < abx

in δacy and δaby,

so, δacy ≅ δaby (side-angle-side or sas)

since δacy ≅ δaby, we can conclude < acy ≅ < aby

now,

< acy ≅ < aby

=> < acx + < xcy ≅ < abx + < xby

=> < acx + < xcy ≅ < acx + < xby   (since < acx ≅ < abx already proved above)

subtracting < acx from both sides, we get

< acx + < xcy -< acx ≅ < acx + < xby -< acx

cancelling out < acx and -< acx from both sides, we get

< xcy ≅ < xby (proved)

y/x of point b= y/x of point a

(i got the same question, this was the correct answer.)
