What are the real or imaginary solutions of the polynomial x^3=9x​

Mathematics
1 answer:
dem82 [27]3 years ago
8 0

Hello from MrBillDoesMath!

Answer:

 x = 0, +\-3


Discussion:

x^3 = 9x              => subtract 9x from both sides

x^3 - 9x = 0         => factor x from both terms

x(x^2-9) = 0        => x = 0 or x^2 - 9 = 0

x = 0, +\-3

Thank you,

MrB

−9x+4y=6 9x+5y=−33 ​
blsea [12.9K]

Answer:

{x,y} = {-2,-3}

Step-by-step explanation:

System of Linear Equations entered :

  [1]    -9x + 4y = 6

  [2]    9x + 5y = -33

Graphic Representation of the Equations :

   4y - 9x = 6        5y + 9x = -33  

Solve by Substitution :

// Solve equation [2] for the variable  y  

 

 [2]    5y = -9x - 33

 [2]    y = -9x/5 - 33/5

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

  [1]    -9x + 4•(-9x/5-33/5) = 6

  [1]    -81x/5 = 162/5

  [1]    -81x = 162

// Solve equation [1] for the variable  x  

  [1]    81x = - 162  

  [1]    x = - 2  

// By now we know this much :

   x = -2

   y = -9x/5-33/5

// Use the  x  value to solve for  y  

   y = -(9/5)(-2)-33/5 = -3

Salsk061 [2.6K]

Answer:

Each marker will be exactly <u>103</u> miles apart.

Step-by-step explanation:

It is given that Ian wants to run 412 miles and has set up 3 markers the same distance apart.

Between the start and end of run, the 3 separate markers will divide the 412-mile distance into 4 equal segments.

So each segment = 412/4 = 103 miles

Each marker will be exactly <u>103</u> miles apart.
