Identify the pattern in the sequence of numbers and choose the missing number in the sequence 8,-2,-6,_,-28,-42
A. -12 because 6 was subtracted from -6
B.-16 because 10 was subtracted from -6
C. -14 because 8 was subtracted from -6
D. -3/2 because -6 was divided by 4

answer: the equation matches the regression

step-by-step explanation:

something over 10 so ? /10

step-by-step explanation:

< 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)
