Larry’s pet store made $30 before a pipe burst and he had to close early to get it fixed. He realized that he lost 3/4 of a dollar each hour that the store was closed. If the expression that models this situation is 30 -3/4x, what is Larry’s profit if the store was closed for 8 hours?

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.

< 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)
