What is 3x+1? They say its really easy and I don't know how.

-------------------------------------------------------------------------------------------------------------

Answer:  \textsf{x = - 1 / 3}

-------------------------------------------------------------------------------------------------------------

Given: \textsf{3x + 1}

Find: \textsf{The value of the unknown variable x}

Solution: In order to solve for x we need to isolate it with the first step being to subtract 1 from both sides and then we would divide both sides by 3 to give us the solution.

<u>Subtract 1 from both sides</u>

  • \textsf{3x + 1 = 0}
  • \textsf{3x + 1 - 1 = 0 - 1}
  • \textsf{3x = 0 - 1}
  • \textsf{3x = - 1}

<u>Divide both sides by 3</u>

  • \textsf{3x / 3 = - 1 / 3}
  • \textsf{x = - 1 / 3}

Therefore, the final answer would be that x is equal to -1/3.

Answer:

  y = -1/4(x +4)² +4

Step-by-step explanation:

The equation of a parabola with focus (a, b) and directrix y=d can be written using the form ...

  y = 1/(2(b-d))(x -a)² +(b+d)/2

<h3>Application</h3>

We are given (a, b) = (-4, 3) and d=5. Using these values in the above form gives the equation ...

  y = 1/(2(3-5))(x -(-4))² +(3+5)/2

  y = -1/4(x +4)² +4
