5n + 34 = -2(1 - 7n)

5n + 34 = -2 + 14n
5n = -36 + 14n
-9n = -36
9n = 36
n = 4

Hi

5n + 34 = -2(1-7n)
5n + 34 = -2 + 14n
5n - 14n = -2 - 34
-9n = - 36
Divide both sides by -9
-9n/-9 = -36/-9
n = 4

If (m, 2) is on a circle with center (−3, 2) and radius 8, what is a value of m?

Talja [164]

$\bf \textit{distance between 2 points}\\ \quad \\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
&({{ -3}}\quad ,&{{ 2}})\quad 
% (c,d)
&({{ m}}\quad ,&{{ 2}})
\end{array}\qquad 
% distance value
d = \sqrt{({{ x_2}}-{{ x_1}})^2 + ({{ y_2}}-{{ y_1}})^2}$

$\bf \textit{we know the distance from m,2 and -3,2(center) is the radius}
\\\\\\
d=8\implies 8=\sqrt{[m-(-3)]^2+[2-2]^2}
\\\\\\
8=\sqrt{(m+3)^2+(0)^2}\implies 8=\sqrt{(m+3)^2}\implies 8^2=(m+3)^2
\\\\\\
64=(m+3)^2\implies \sqrt{64}=\sqrt{(m+3)^2}\implies 8=m+3
\\\\\\
8-3=m$
