<h3>Hmm, I think it might be 2 because its just a smaller version of the other triangles but if its wrong then the possible answer is 5 cause 5 looks just like 1 don't ya think?</h3>

If: \qquad AC = 64 AB = 7x + 8, and BC= 3x+6, Find BC

Nady [450]

The answer is 21.

First you Add both AB and BC which is 10x +14. Then you put 64 into the equation. 10x+14=64. Subtract 14 from 64 which is 50. So 10x=50. Then divide 10 from 50. which would be x=5. So if you plug it in. It would be 21.

Find the equation of a line that passes through the points (-1,5) and (3,-3). Write the equation in slope-intercept, point-slope

Vesnalui [34]

$\bf (\stackrel{x_1}{-1}~,~\stackrel{y_1}{5})\qquad 
(\stackrel{x_2}{3}~,~\stackrel{y_2}{-3})
\\\\\\
slope = m\implies 
\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-3-5}{3-(-1)}\implies \cfrac{-3-5}{3+1}\implies -2
\\\\\\
\stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-5=-2[x-(-1)]
\\\\\\
\boxed{y-5=-2(x+1)}\implies y-5=-2x-2\implies \boxed{\stackrel{slope-intercept~form}{y=-2x+3}}
\\\\\\
\boxed{\stackrel{standard~form}{2x+y=3}}$
