Answer:

Parabolas always have a lowest point (or a highest point, if the parabola is upside-down). This point, where the parabola changes direction, is called the "vertex". If the quadratic is written in the form y = a(x – h)2 + k, then the vertex is the point (h, k). This makes sense, if you think about it.

step by step:

1. Get the equation in the form y = ax2 + bx + c.

2.Calculate -b / 2a. This is the x-coordinate of the vertex.

3.To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y. This is the y-coordinate of the vertex.

2x + 1=4x-3 solve for x
loris [4]

Answer:

x = 2

Step-by-step explanation:

To start, you want to isolate x.

To do so, get all the x terms to one side.

2x + 1 = 4x - 3

Subtract -4x on both sides.

-2x + 1 = -3

Then, subtract 1 on both sides.

-2x = -4

Finally, divide -2 on both sides.

x = 2

Help find x. I believe it’s 13
aksik [14]

Answer:

m∠RST = 155°

m∠RSU = 102°

Step-by-step explanation:

m∠RST  = m∠RSU + m∠UST

12x - 1    = 9x - 15 + 53

12x - 9x = 1- 15 + 53

      3x   = 39

        x   = 39/3

         x = 13°

m∠RST  = (12x -1)° = (12 * 13 - 1)° =   (156 - 1 )° = 155°

m∠RSU = (9x -15)° = (9 * 13 - 15)° = ( 117 - 15)° = 102°
