Makayla works as a teacher at Dacula Middle School. She earns $150 just for coming to work and an additional $200 for each hour worked. The linear function T(x) = 200x + 150 represents Makayla's earnings T as a function of time worked x (in hours). Solve and interpret the meaning of T(7) in the context of this problem. A. T(7) = 1550; Makayla worked 7 hours and earned $1,550.
B T(7) = 1250; Makayla worked 7 hours and earned $1,250.
C T(7) = 200; Makayla worked 7 hours and earned $200.
D T(7) = 150; Makayla worked 7 hours and earned $150

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

< 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)
