Question

check my work please

Answer 1

if f(x)= 3x+2
then, we have:
f(2)= 3*2+2=8 so your answer is right

Answer 2

we have:
\[{f^{ - 1}}\left( x \right) = \frac{{3x + 7}}{2}\]

Answer 3

so we get:
\[{f^{ - 1}}\left( 3 \right) = \frac{{3 \times 3 + 7}}{2} = 8\]

Answer 4

question #3
if we add 2 to both sides, we have:
\[\begin{gathered}
2y + 14 + 2 = 4y - 2 + 2 \hfill \\
\hfill \\
2y + 16 = 4y \hfill \\
\end{gathered} \]

Answer 5

now we have to subtract 2y from both sides so we get:
\[\begin{gathered}
2y + 16 - 2y = 4y - 2y \hfill \\
16 = 2y \hfill \\
\end{gathered} \]

Answer 6

finally I divide both sides by 2, so I can write:
\[\begin{gathered}
\frac{{16}}{2} = \frac{{2y}}{2} \hfill \\
\hfill \\
y = 8 \hfill \\
\end{gathered} \]

Answer 7

so your answer is right!

Answer 8

no, I can't do what you ask to me, there is no reason for that

Answer 9

okay
