ban dang thi a???

a,

c, Gọi \(\left(D_3\right):y=ax+b\) là đt cần tìm

\(\Leftrightarrow\left\{{}\begin{matrix}a=-2;b\ne0\\3x+3=ax+b,\forall x=-1\end{matrix}\right.\Leftrightarrow\left\{{}\begin{matrix}a=-2\\-a+b=0\end{matrix}\right.\Leftrightarrow\left\{{}\begin{matrix}a=-2\\b=-2\end{matrix}\right.\)

Vậy \(\left(D_3\right):y=-2x-2\)

\(20,18.7,5+20,18+20,18:2\\ =20,18.\left(7,5+1+0,5\right)\\ =20,18.9\\ =181,62\)

\(20,18\times7,5+20,18+20,18:2\)
\(=20,18\times7,5+20,18\times1+20,18\times0,5\)
\(=20,18\times\left(7,5+1+0,5\right)\)
\(=20,18\times9\)
\(=181,62\)
