Which option gives f(x) = x² - 4x - 12 rewritten in vertex form as well as the function's correct axis of symmetry ?
f(x) = (x - 2)² - 16, x = - 16
f?(x) = (x + 2)(x - 6), x = 6
f(x) = (x + 2)(x - 6), x = -2
f(x) = (x - 2)² - 16, x = 2

k
where (h, k) is the vertex of the parabola.
when written in vertex form
(h, k) is the vertex of the parabola and x = h is the axis of symmetry
the h represents a horizontal shift (how far left, or right the graph has shifted from x = 0)
the k represents a vertical shift (how far up, or down the graph has shifted from y = 0)

The function f(x) = x² - 4x - 12 in vertex form is f(x) = (x - 2)² - 16, and the axis of symmetry is x = 2.
To rewrite the function f(x) = x² - 4x - 12 in vertex form and find the axis of symmetry, we need to complete the square. The general vertex form of a quadratic is f(x) = a(x - h)² + k, where (h, k) is the vertex, and the line x = h is the axis of symmetry.
The first step is to factor the coefficient of x², which is 1 in this case, so we can leave it as is. The next step is to rearrange the equation as x² - 4x and then add and subtract the square of half the coefficient of x, which is (4/2)² = 4. Adding and subtracting 4 inside the parentheses gives us:
f(x) = (x² - 4x + 4) - 4 - 12
Now we can rewrite this as:
f(x) = (x - 2)² - 16
This equation is in vertex form, with the vertex at (2, -16), and the axis of symmetry is the line x = 2.
Therefore, the correct option is f(x) = (x - 2)² - 16, with the axis of symmetry being x = 2.
What is the coefficient of the c-term of the algebraic expression 14 a minus 72 r minus c minus 34 d?
When there's no number in front of a variable, that means it has a coefficient of 1.
So the coefficient is 1. Hope that makes sense.
The coefficient of the c-term of the algebraic expression 14a - 72r - c - 34d is -1.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
We have an algebraic expression:
= 14a - 72r - c - 34d
From the above equation, the coefficient of the c term is:
= -1
Thus, the coefficient of the c-term of the algebraic expression 14a - 72r - c - 34d is -1.

Which expression is equivalent to 6y - 12
Answer:-12+6y
Step-by-step explanation:
Since the 12 is a negative and the 6y is a positive you can switch it around.
The expression 6y - 12 is equivalent to 6(y - 2). This can be verified by expanding the factored form, which results in the original expression.
This expression can be factored to find an equivalent expression. Factoring out the greatest common factor (GCF) from both terms, we get:
6y and 12. The GCF is 6.Factor out the GCF: 6(y - 2).Thus, the expression 6y - 12 is equivalent to 6(y - 2).

a sign says that the price marked on all music equipment is 30% off the original price you buy an electric guitar for sale price of $315 what is the original price
The original price is $450.
Step-by-step explanation:
Step 1:
Given details, Discount%, D% = 30 and Selling Price, SP = $315
Step 2:
Write down formula for calculating the Original Price
Selling Price (SP) = Original Price (OP) - Discount (D)
Discount (D) = Original Price (OP) * (D%/100)
Step 3:
Substitute given values in the formula
315 = OP - D
D = [tex]OP \times30/100[/tex]
D = 0.3 OP
Step 4:
Substitute value of D in the first formula
315 = OP - 0.3 OP
315 = OP (1 - 0.3) = 0.7 OP
Original Price, OP = 315/0.7 = $450

simplify 3(4x+7)−4(12x−15)
The expression 3(4x+7)−4(12x−15) simplifies to -36x + 81. First distribute the constants to the terms inside the parentheses, then combine like terms.
Explanation:In mathematics, to simplify an algebraic expression like 3(4x+7)−4(12x−15), you need to perform the operations in a certain order, respecting the laws of arithmetic. This is often referred to as simplifying the expression using the distributive property.
First, distribute the 3 to both of the terms in the first set of parentheses: 3 * 4x + 3 * 7 equals 12x + 21.Next, distribute the -4 to both of the terms in the second set of parentheses: -4 * 12x -4 * -15 equals -48x + 60.Combine like terms: 12x - 48x equals -36x. Similarly, 21 + 60 equals 81.So the original expression, 3(4x+7)−4(12x−15), simplifies to -36x + 81.Learn more about Simplifying Algebraic Expressions here:

The required measure of the angle m∠6 is given as 58 degrees. Option B is correct.
What is the angle?Orientation of the one line with respect to the horizontal or other respective line is known as a measure of orientation and this measure is known as the angle.
Here,
For the bisection of parallel line by transversal line,
Corresponding angles always have an equal measure,
So, ∠2 = ∠6
Now,
∠2 + ∠3 = 180
∠6 + 122 = 180
∠6 = 58°

Lines RT and SV are the diagonals of the parallelogram RSTV.
Step 2 :
The diagonals of a parallelogram bisect each other . (Properties of a parallelogram)
Step 3 :
Given that the diagonals RT and SV intersect at Q, we have QT = RQ.

Given that,
The function S(D) =(7/2) √2D can be used to approximate the speed S, in miles per hour, of a car that has left skid marks of length D, in feet, how fast would a car have been traveling if it left a skid mark that is 102.04 feet long is to be determined.
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
Given the function of speed,
S(D) =(7/2) √(2D)

Hana wants to buy a charm bracelet. Dayton Fine Jewelry charges $17 per charm, plus $62 for the bracelet. Cain Jewelers, in contrast, charges $18 per charm and $60 for the bracelet. If Hana wants to add a certain number of charms to her bracelet, the cost will be the same at either jewelry shop. What would the total cost of the bracelet be? How many charms would that be?
Final answer:
To determine the number of charms for the bracelet to cost the same at both jewelry shops, we set up a system of equations and solved it using substitution. We found that Hana will need to add 2 charms, resulting in a total cost of $96 for the bracelet at either shop.
Explanation:
To determine the number of charms Hana can add to her bracelet such that the cost is the same at Dayton Fine Jewelry and Cain Jewelers, we need to set up a system of equations and solve using the substitution method.
System of Equations:
Let x represent the number of charms and y represent the total cost of the bracelet with charms.
Equation for Dayton Fine Jewelry: y = 17x + 62
Equation for Cain Jewelers: y = 18x + 60
Solution Using Substitution:
Set the two equations equal to each other since the cost is the same:Hana will need to add 2 charms to her bracelet, and the total cost of the bracelet will be $96 at either jewelry shop.

From the question,Jed’s shower head releases
6.2 gallons = 1 minute
x gallon = 5 mins 12 secs
First convert 12 secs to minutes and add it to 5 mins .
1 minute = 60secs
x minute = 12 secs
x = 12/60
= 0.2 mins + 5 mins
= 5.2 mins

6.2 gallons = 1 minute
x gallons = 5.2 mins
Cross multiply
x = 6.2 x 5.2 /1

A group of seventh graders and a group of teachers at a local middle school were asked how many siblings they each have. The dot plots below show the results.
When comparing the shape of the two sets of data, what conclusion can someone draw?
The students tend to have fewer siblings than the teachers.
The teachers tend to have fewer siblings than the students.
Both the students and the teachers have a wide range of siblings.
Both sets of data have the same shape.
First, we need to find out how many siblings the students have in total and how many siblings the teachers have in total.
The students: (1 x 4) = 4 + (2 x 7) = 18 + (3 x 5) = 33 + (4 x 2) = 41. The students have a total of 41 siblings.
The teachers: (1 x 3) = 3 + (2 x 2) = 7 + (3 x 4) = 19 + (4 x 5) = 39 + (5 x 3) = 54 + (6 x 1) = 60 + (8 x 1) = 68. The teachers have a total of 68 siblings.
Now that we have this information, we know that the answer is option 1, the students tend to have fewer siblings than the teachers. This is because the students had a total of 41 siblings and the teachers had a total of 68 siblings, and 41 is less than 68 so the students have fewer siblings than the teachers.
