Answer:

Step-by-step explanation:

Put the equation in the form ax+by+c=0:

y\sqrt{3} =8x+\sqrt{3} \\=>8x-\sqrt{3} y+\sqrt{3} =0

Check the solutions:

(0,-1):

8(0)-\sqrt{3} (-1)+\sqrt{3} =2\sqrt{3}

So this is not a solution.

((\sqrt{3} ,9):

8\sqrt{3} -9\sqrt{3} +\sqrt{3} =0

So this is a solution

Simplify 2ab/3cd×c²d²/ab²​
gulaghasi [49]

\frac{2ab}{3cd}  \times  \frac{c²d²}{ab²}

=  \frac{2cd}{3b}

= (\frac{2}{3} ) \frac{cd}{b}

= 0.66 \frac{cd}{b}

X/-2=4, X/3+13=13, Z/2+2=4 plz show ur work and explain how u did it
AVprozaik [17]
\dfrac{x}{-2}=4\ \ \ |multiply\ both\ sides\ by\ (-2)\\\\(-2)\cdot\dfrac{x}{-2}=(-2)\cdot4\\\\\boxed{x=-8}\\\\\dfrac{x}{3}+13=13\ \ \ |subtract\ 13\ from\ both\ sides\\\\\dfrac{x}{3}+13-13=13-13\\\\\dfrac{x}{3}=0\ \ \ |multpily\ both\ sides\ by\ 3\\\\\not3^1\cdot\dfrac{x}{\not3_1}=0\\\\\boxed{x=0}

\dfrac{z}{2}+2=4\ \ \ |subtract\ 2\ from\ both\ sides\\\\\dfrac{z}{2}+2-2=4-2\\\\\dfrac{z}{2}=2\ \ \ \ |multiply\ both\ sides\ by\ 2\\\\\not2^1\cdot\dfrac{z}{\not2_1}=2\cdot2\\\\\boxed{z=4}
