Answer:

x=2

Step-by-step explanation:

To find the axis of symmetry for a quadratic, you use the formula:

x=-2ba

Looking at the chart, we can see that b=-1 (the vertical shift) and a=1 (the slope. Plugging these values into the formula, we get:

x=-2(-1)(1)=2

Therefore, x=2 is the axis of symmetry.

The much simpler way of determining this, however, is simply looking at the graph and finding where the vertex is. It is given here that the vertex point is (2, -1) and the graph is mirrored horizontally so you can simply take the x-coordinate and that will be the axis of symmetry. If the parabola was mirrored vertically, the axis of symmetry would then be the y-coordinate of the vertex.

Answer:

x = 2

Step-by-step explanation:

The axis of symmetry is a vertical line passing through the vertex, with equation

x = c ( c is the x- coordinate of the vertex ) , then

x = 2 ← equation of axis of symmetry

1. is he equation true , false, or open

Question 1:

For this case we have the following equation:

 5x ^ 2 = 6x + 11

We observe that the equation is a polynomial of the second degree.

Therefore, the equation has two possible solutions.

The variable of the equation for this case is x.

In this case, we have an open equation because we have a variable.

Rewriting the equation we have:

5x ^ 2 - 6x - 11 = 0

Answer:

open, there is a variable.


Question 2:

For this case we have the following equation:

 2-8x = -6

From here, we must clear the value of x.

For this, we follow the following steps:

1) Pass the value of 8x adding:

2 = -6 + 8x

2) Pass the value of 6 adding:

2 + 6 = 8x

3) Add the values ​​on the same side of equality:

 8x = 8

4) Pass the 8 to divide:

x = \frac{8}{8} = 1

Answer:

The value of x is given by:

x = 1


Question 3:

For this case we have the following equation:

 y = x-4

The ordered pair solution is the one that satisfies both sides of the equation.

For the point (6, 2) we have:

x = 6  y = 2

Substituting values ​​we have:

2 = 6-4  2 = 2

We observe that both sides of the equation are equal.

Therefore, the ordered pair solution is (6, 2)

Answer:

An ordered pair that is a solution of the equation y = x-4 is:

(6, 2)

inessss [21]
You can not use either of them because neither of them have a variable= to the eqaution
ex.) y= 3x+25
