i need to write an inequality for the raph
OpenStudy (michele_laino):
hint:
if you make this change of variable, namely from x, y to X, Y, where X, Y are the new variable:
\[\left\{ \begin{gathered}
x = X + 5 \hfill \\
y = Y + 1 \hfill \\
\end{gathered} \right.\]
then the equation of your graph is:
\[\left| Y \right| = \left| X \right|\]
OpenStudy (<3pandas18):
so would it be y=5?
OpenStudy (<3pandas18):
no wait y=x+5-1?
Still Need Help?

i am so confused
OpenStudy (michele_laino):
you have to replace Y with y-1, and X with x-5 in the subsequent formula:
\[\left| Y \right| = \left| X \right|\]
OpenStudy (<3pandas18):
wait ik now y=lx+(-5)l +1?
OpenStudy (<3pandas18):
y=lx-5l+1?
OpenStudy (michele_laino):
the right formula is :
\[Y = \left| X \right|\]
so after the substitution above, we get this:
\[y - 1 = \left| {x - 5} \right|\]

therefore, you are right!
OpenStudy (<3pandas18):
y=lx-5l+1?
OpenStudy (<3pandas18):
ooooo ok thnks!
OpenStudy (michele_laino):
correct!
OpenStudy (michele_laino):
please, note that the subsequent formula:
\[\left| Y \right| = \left| X \right|\]
is wrong
