Which ordered pairs are in a proportional relationship with (0.2, 0.3)?
A
(1.2, 2.3)
B
(2.7. 4.3)
C
(3.2, 4.8)
D
(3.5, 5.3)
E
(5.2, 7.8)

it would be 6xy and -16xy.

so, converting firstly the mixed fractions to improper fractions and then "adding".

< 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)
