Vertex of a quadratic function:
Suppose we have a quadratic function in the following format:
[tex]f(x) = ax^{2} + bx + c[/tex]
It's vertex is the point [tex](x_{v}, y_{v})[/tex]
In which
[tex]x_{v} = -\frac{b}{2a}[/tex]
[tex]y_{v} = -\frac{\Delta}{4a}[/tex]
Where
[tex]\Delta = b^2-4ac[/tex]
If a<0, the vertex is a maximum point, that is, the maximum value happens at [tex]x_{v}[/tex], and it's value is [tex]y_{v}[/tex].
Turning point of a quadratic function:
The turning point of a quadratic function is the vertex.
y = x2 — 6x + 8
This means that [tex]a = 1, b = -6, c = 8[/tex]
Now, we find the vertex.
[tex]x_{v} = -\frac{b}{2a} = -\frac{-6}{2(1)} = 3[/tex]
[tex]\Delta = b^2-4ac = (-6)^2-4(1)(8) = 36 - 32 = 4[/tex]
[tex]y_{v} = -\frac{4}{4(-1)} = -1[/tex]
(x,y) = (3,-1), and the correct answer is given by option D.

Which equation represents a line which is perpendicular to the line 6x+y=-4
Answer:
y = 1/6x - 4
Step-by-step explanation:
y = -6x - 4
current slope is -6 so the slope of a line perpendicular would be 1/6
y = 1/6x - 4
what is the value of x? 0 = x/6 - 3
Answer:
18 = x
Step-by-step explanation:
0 = x/6 - 3
Add 3 to each side
0+3 = x/6-3+3
3 = x/6
Multiply by 6 on each side
3*6 = x/6*6
18 = x

X=
A) x = 123, y = 4 4
B) x=3, y = 0
C) No solution
D) Infinitely many solutions
Answer:
no solution.
Step-by-step explanation:
given that, y = 3x-1
so,
in equation, 3x-y = 9
putting the value of y here,
3x-(3x-1) = 9
3x-3x+1 = 9
3x and 3x is cancelled.
hence, no solution
Solve for x in the equation

A circle has a center at (-2, 5) and a radius of bold 3 square root of bold 2units. What is the equation of the circle in standard form?
Given:
The center of the circle = (-2,5)
The radius of the circle = [tex]3\sqrt{2}[/tex] units.
To find:
The equation of the circle is standard form.
Solution:
The standard form of a circle is:
[tex](x-h)^2+(y-k)^2=r^2[/tex] ...(i)
Where, (h,k) is the center of the circle and r is the radius of the circle.
It is given that the center of the circle is (-2,5). So, [tex]h=-2,\ k=5[/tex].
The radius of the circle is [tex]3\sqrt{2}[/tex] units. So, [tex]r=3\sqrt{2}[/tex].
Putting [tex]h=-2,\ k=5[/tex] and [tex]r=3\sqrt{2}[/tex] in (i), we get
[tex](x-(-2))^2+(y-(5))^2=(3\sqrt{2})^2[/tex]
[tex](x+2)^2+(y-5)^2=18[/tex]
Therefore, the equation of the circle is [tex](x+2)^2+(y-5)^2=18[/tex].

Jeanne goes to the city park every 7 days for walk. Susan goes to the park every 10 days. If they both went to the park today and met each other, after how many days again will they be in the park and meet again?
Answer:
70 days
Step-by-step explanation:
We solve using Lowest Common Denominator method
Find and list multiples of each number of days for a walk until the first common multiple is found. This is the lowest common multiple.
Jeanne goes to the city park every 7 days for walk. Susan goes to the park every 10 days.
Hence:
Multiples of 7:
7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84
Multiples of 10:
10, 20, 30, 40, 50, 60, 70, 80, 90
Therefore,
LCM(7, 10) = 70
Therefore, the number of days in which they will they be in the park and meet again is 70 days

A horizontal line passes through the point (5, –1). Which point is also on this line?
(0, 0)
(–1, 5)
(5, –4)
(–2, –1)
Answer:
Step-by-step explanation:
A horizontal line is a "y = " line. So the horizontal line that goes through the point given has the equation y = -1 (-1 being the y coordinate of the point). That means that another point on this line, y = -1, will also have to have a y coordinate of -1. The only one is the last one, (-2, -1).

there are 13 apples in a basket 4 of these apples are green the rest of them are red
Answer:
9 : 13
Step-by-step explanation:
Here is the complete question :
there are 13 apples in a basket 4 of these apples are green the rest of them are red
What what is the ratio of red apples to all the apples in the basket
Ratio expresses the relationship between two or more numbers. It shows the frequency of the number of times that one value is contained within other value(s).
ratio of red apples to all the apples in the basket = Number of red apples : total number of apples
Number of red apples = total number of apples - number of green apples
13 - 4 = 9
9 : 13

Answer:
The range of both [tex]f(x)[/tex] and [tex]g(x)[/tex] is all nonzero real numbers.
Step-by-step explanation:
The range of the function is the set of real number for [tex]y[/tex]. The rational function of the form [tex]y = \frac{a}{x}[/tex], where [tex]a[/tex] is a constant, has a range represented by the subset of nonzero real numbers. This is: [tex]Ran\{f(x)\} = \mathbb{R}-\{0\}[/tex]

Una maestra esta comprando lapices para su salon de clases. Si una docena de lapices cuesta $0.79 puede comprar lapices con $5?
Answer:
Cantidad total de lapices= 76
Step-by-step explanation:
Dada la siguiente información:
Costo por docena= $0.79
Presupuesto total= $5
Para calcular la cantidad total de lapiceras que se pueden comprar con $5, debemos usar la siguiente formula:
Cantidad total de lapices= presupuesto total / costo por docena
Cantidad total de lapices= 5 / 0.79
Cantidad total de lapices= 6.33
Para ser mas exactos:
0.33*12= 4
Cantidad total de lapices= 6*12 + 4
Cantidad total de lapices= 76

For the arithmetic sequence beginning with the terms {-2, 0, 2, 4, 6, 8...}, what is the sum of the first 18 terms?
Answer:
The sum of the first 18 terms is 270.
Step-by-step explanation:
First the 18th term is calculated which is gotten using the following steps below:
an = a1 + d ( n - 1 )
Where, an =18th term
a1= first term (-2)
d = difference
n = 18
Therefore, 18th term
an= -2 + 2 (18 - 1)
= -2 + 2 (17)
= -2 + 34
18th term = 32
To calculate the sum of the first 18th terms the following steps are used,
Sn = n(a1 + an)/2
Where,
Sn = sum of 18th term
n = 18
a1 = -2
an = 18 term
Therefore,
Sn = 18 (- 2+ 32)/2
= 18 (30)/2
= 18 ×30 /2
= 540/2
= 270

What is the reflection of point P (2, -7) over the x-axis
Answer:
(2,7) I think
Step-by-step explanation:
Answer:
(2,7)
Step-by-step explanation:
It's funny, this is the exact topic I just learned.
Ok, 2,-7 would be in the fourth quadrant (IV).
So using this information if we want to reflect it over the x axis, the point would just got over the x axis in quadrant 1. We know that quadrant 1 is (++) so the ordered pair MUST be positive. Hence the answer of (2,7)

A number line going from 0 to 3. A closed circle is at 2. Everything to the left of the circle is shaded.
A number line going from 0 to 3. An open circle is at 2. Everything to the left of the circle is shaded.
A number line going from 0 to 3. An open circle is at 2. Everything to the right of the circle is shaded.
Answer:
A number line going from 0 to 3. An open circle is at 2. Everything to the left of the circle is shaded.
Step-by-step explanation:
First, remember that when an endpoint is not in the solution set, we graph an open circle. While if the endpoint is in the solution set, we graph it with a closed circle.
For example, in:
x > 2
x = 2 is not a solution, then we will have an open circle at x = 2
While in the case of:
x ≥ 2
x = 2 is a possible solution, then we graph with a closed circle.
Ok, in this case we have:
t < 2
t is strictly smaller than 2, and t = 2 is not a solution.
Then:
we will have an open circle at 2, and we need to shade all the values to the left of 2 (the values smaller than 2)
The correct option is:
A number line going from 0 to 3. An open circle is at 2. Everything to the left of the circle is shaded.
Answer:
the middle one.
