What’s this answer I forgot it

7.25

Step-by-step explanation:

You can pick any two pair from the table and will give you the same answer. I will pick the first and the last pair.

(2, 14.50) and (8, 58.00)

x1, y1 x2, y2

Rate of change = y2 - y1 / x2 - x1

Rate of change = 58.00 - 14.50 / 8 - 2

Rate of change = 43.50 / 6

Rate of change = 7.25

Hope this helps, thank you :) !!

< 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)
