Answer:

2x+8y=20;y=2  

Solution :

{x,y} = {2,2}  

 

System of Linear Equations entered :

  [1]    2x + 8y = 20

  [2]    y = 2

Graphic Representation of the Equations :

   8y + 2x = 20        y = 2  

 

 

Solve by Substitution :

// Solve equation [2] for the variable  y  

  [2]    y = 2  

// Plug this in for variable  y  in equation [1]

  [1]    2x + 8•(2) = 20

  [1]    2x = 4

// Solve equation [1] for the variable  x  

  [1]    2x = 4  

  [1]    x = 2  

// By now we know this much :

   x = 2

   y = 2

We are done

Solution :

{x,y} = {2,2}

Solve using quadratic formula<br> 6x^2-x=2
Nadya [2.5K]

6x^2-x=2\implies 6x^2-1x-2=0 \\\\[-0.35em] ~\dotfill\\\\ ~~~~~~~~~~~~\textit{quadratic formula} \\\\ \stackrel{\stackrel{a}{\downarrow }}{6}x^2\stackrel{\stackrel{b}{\downarrow }}{-1}x\stackrel{\stackrel{c}{\downarrow }}{-2}=0 \qquad \qquad x= \cfrac{ - b \pm \sqrt { b^2 -4 a c}}{2 a}

x = \cfrac{ -(-1) \pm \sqrt { (-1)^2 -4(6)(-2)}}{2(6)}\implies x = \cfrac{1\pm\sqrt{1+48}}{12} \\\\\\ x = \cfrac{1\pm\sqrt{49}}{12}\implies x = \cfrac{1\pm 7}{12}\implies x = \begin{cases} \frac{8}{12}\to &\frac{2}{3}\\[1em] -\frac{6}{12}\to &-\frac{1}{2} \end{cases}

Answer:

28 . 26cm

Step-by-step explanation:

First find the radius

d = 2r \\ 9 = 2r \\  \frac{9}{2}  =  \frac{2r}{2}  \\ r = 4.5

Now find the CIRCUMFERENCE

c = 2\pi \: r \\  = 2 \times \pi \times 4.5 \\  = 9 \times \pi \\  = 28.26
