Answer:

the last one I think

Step-by-step explanation:

The vertex form of the quadratic equation is:

[tex]g(x) = (x + 1)^2 - 2[/tex]

And the graph can be seen at the end

For a quadratic equation with leading coefficient a, and with vertex (h, k), the vertex form is:

[tex]y = a*(x - h)^2 + k[/tex]

Here we have:

[tex]g(x) = x^2 + 2x - 1[/tex]

First, we need to find the vertex. by using the known formula we get:

[tex]h = -2/(2*1) = -1[/tex]

To get the value of k, we need to evaluate g(x) in x = -1.

[tex]g(-1) = (-1)^2 + 2*-1 - 1 = 1 - 2 - 1 = -2[/tex]

So the vertex is (-1, -2), which means that the vertex form is:

[tex]g(x) = (x + 1)^2 - 2[/tex]

And its graph can be seen below.

Step-by-step explanation:

Quadratic Equation Solving

The standard representation of a quadratic equation is:

[tex]ax^2+bx+c=0[/tex]

where a,b, and c are constants.

Solving with the quadratic formula:

[tex]\displaystyle x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

We have the following equation to solve:

[tex]x+x^2-5x-5=0[/tex]

Before attempting to solve it, we must simplify the equation.

Collecting like terms and reordering:

[tex]x^2-4x-5=0[/tex]

Here: a=1, b=-4, c=-5

The discriminant of this quadratic equation is:

[tex]d=b^2-4ac[/tex]

[tex]d=(-4)^2-4(1)(-5)=16+20=36[/tex]

Given d is positive, the equation has two roots, and since d is a perfect square, both roots are rational.

Applying the formula:

[tex]\displaystyle x=\frac{4\pm \sqrt{36}}{2(1)}[/tex]

[tex]\displaystyle x=\frac{4\pm 6}{2}[/tex]

Dividing by 2:

[tex]x=2\pm 3[/tex]

Separating both roots:

x = 2 + 3 = 5

x = 2 - 3 = -1

The zeros of the polynomial are -1 and 5

Answer:

There's 15 cows and 35 chickens.

Step-by-step explanation:

Take 20 and multiply it by 2. The answer is 40. Then subtract 40 from 130. The answer will be 90. The cow has double the amount of legs than the  chicken, so the cow is equivalent to 2 chicken. Divide 90 by 3. The answer is 30. Then divide 30 by 2 the answer is 15. Add 15 and 20 and the answer is 35 chickens. Divide 30 by 2 and the answer is 15.

You will get 35 chicken and 15 cows as your answer. Happy Election Night, and I hope this helps! ;)

Step-by-step explanation:

Median tells the average weight. Like, what your corgi might weight.

The median tells us about the center level of all the weights.

The median is a statistical measure that represents the central value of a dataset when it is arranged in ascending or descending order. It is the value that separates the higher half of the data from the lower half.

From the given table, we can determine that the median weight of the Welsh corgis is 27.3. The median represents the middle value of a dataset when it is arranged in ascending or descending order.

In this case, it tells us that half of the Welsh corgis in the sample have weights below 27.3, and the other half have weights above 27.3.

So, the median tells us about the center level of all the weights.

Write an equation in slope-intercept form for the line that passes through (6,- 3) and is parallel to y = -2x + 4.

__________________________________________________________

Parallel lines are lines with the same slope but different y-intercept.

Slope-intercept form is written as y=mx+b, where m is the slope and b is the y-intercept.

__________________________________________________________

The given line is y=-2x+4. A line parallel to this would have the same slope, which is -2. To find the y-intercept, plug the point into an equation in point-slope form.

[tex]\displaystyle \text{Point-Slope Form} \rightarrow y-y_{1}=m(x-x_{1})[/tex]

m is the slope, and since the slope is the same as the given line, m will be equal to 2.

The line is supposed to pass through a point, which is written as (x, y). In this line, it is supposed to pass (6, -3). x₁ will be the x value of the point, and y₁ will be the y value of the point. That means x₁ is 6 and y₁ is -3.

Substitute the values into the formula:

[tex]y-y_{1}=m(x-x_{1}) \rightarrow y-(-3)=2(x-6)[/tex]

When subtracting a negative number from a number or variable, the sign will change, and the number will become positive.

[tex]y-(-3)=y+3[/tex]

Here is the new equation:

[tex]y-3=2(x-6)[/tex]

Distribute the 2 to everything in the parentheses. It will be 2 times x and 2 times -6. Remember that a positive number multiplied by a negative number is negative.

[tex]2 \times x=2x\\2 \times -6=-12\\\\2(x-6)=2x-12[/tex]

Rewrite the equation:

[tex]y-3=2x-12[/tex]

Lastly, you need to move -3 to the other side, as slope-intercept form is written as y=mx+b. You can move it by adding three(+3) to both sides, which is simply doing the opposite of it(-3+3=0).

[tex]\displaystyle y-3+3=2x-12+3[/tex]

[tex]y=2x-9[/tex]

The answer to your question is [tex]\bf \displaystyle y=2x-9[/tex].
