The answer is x = -4.
Applying the square root property of equality basically means that we need to take the square roots of both sides.

$\sqrt{(x+9)^{2} }= \sqrt{25}$

Which turns into: $x+9=5$

Then we can isolate x by subtracting 9 from both sides: $x=-4$

What is the x intercept of the equation that passes through (1,-6) and is perpendicular to y=1/3x +1

$\bf y=\stackrel{slope}{\cfrac{1}{3}}x+1\impliedby \textit{slope of this line, so a perpendicular will be}
\\\\\\
\textit{perpendicular, negative-reciprocal slope for}\quad \cfrac{1}{3}\\\\

$\bf slope = m\implies -3
\\\\\\
% point-slope intercept
\stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-(-6)=-3(x-1)

y+6=-3x+3\implies 0+6=-3x+3\implies 3=-3x\implies \cfrac{3}{-3}=x

25 X 8 = 200

500 - 200 = 300

So if you have 8 weeks and spend 25 dollars a week then you would have $300 left over at the end of the 8 weeks.
