Draw the line passing through the point (3,-4) with a slope of 2/3
AleksAgata [21]
You just find the coordinate point. then, use your slope 2/3 (up 2, right 3) :)

EX: if your slope was negative, you’d do the same thing, but opposite -2/-3 (down 2, left 3)

hopefully this helps, good luck with math!! <3

(ps sorry if the drawing bothers you, but I wanted to show you as best as I could on how to solve your question :) )

3cot^(2 )x-1=0<br><br> Pls Help
Elina [12.6K]

Answer:

x=\frac{\pi }{6} ,\frac{7\pi }{6}

Step-by-step explanation:

3*cot^2x-1=0\\\\3*cot^2x=1\\\\cot^2x=\frac{1}{3} \\\\cot(x)=\sqrt{\frac{1}{3} } \\\\cot(x)=\frac{1}{\sqrt{3} } \\\\\frac{1}{tan(x)}=\frac{1}{\sqrt{3} } \\\\tan(x)=\sqrt{3} \\

x=tan^-1(\sqrt{3})

It has to be in Quadrant 1  \frac{+}{+} =+ or 3 \frac{-}{-}=+ for positive.

x=\frac{\pi }{6} ,\frac{7\pi }{6}

Unless that incorrect due to tan(x) range is -\frac{\pi }{2} \leq x\leq \frac{\pi }{2}. Then the only answer is x=\frac{\pi }{6}
