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).

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.

During one waiter's shift, he delivered 13 appetizers, 17 entrees, and 10 desserts. what percentage of the dishes he delivered were
Question
During one waiters shift he delivered 13 appetizers, 17 entrées, and 10 desserts what percentage of the dishes he delivered were: A. Desserts B. Appetizers C. entrees
Answer:
A)Desserts = 25 %
B)Appetizers = 32.5 %
C)Entrées = 32.5 %
Step-by-step explanation:
Given:
Number of appetisers = 13
Number of entrees = 17
Number of desserts = 10
Solution:
Total number of dishes = 13 + 17 + 10 = 40
percentage of the dishes he delivered were Desserts is = [tex]\frac{10}{40} \times 100 = 0.25 \times 100 = 25%[/tex]
percentage of the dishes he delivered were Appetizers is =[tex]\frac{13}{40}\times 100 = 0.325 \times 100[/tex] = 32.5%
percentage of the dishes he delivered were Entrées is = [tex]\frac{17}{40} \times 100 = 0.425 \times 100[/tex]= 42.5 %
To find the percentage of each type of dish a waiter has delivered, add up the total number of dishes, then divide the number of each type of dish by this total and multiply by 100.
Explanation:The subject question requires us to determine what the percentage is of the various types of dishes a waiter delivers during his shift. We're given that the waiter delivered 13 appetizers, 17 entrees, and 10 desserts. We can solve this by doing some basic calculations:
First, we need to figure out the total number of dishes the waiter delivered. We do this by adding together the appetizers, entrees, and desserts he delivered: 13 appetizers + 17 entrees + 10 desserts = 40 dishes in total.
Next, to find the percentage of each type of dish, we divide the number of that type of dish by the total number of dishes, and then multiply the result by 100. For example, for appetizers: (13 appetizers / 40 total dishes) * 100 = 32.5%.
You can do the same calculations for entrees and desserts to find their percentages. These basic calculations are useful not only in a restaurant setting, but also in allocation of tasks in modern businesses and in many other real-world scenarios.

Fred spent half of his allowance going to the movies. He washed the family car and earned 9 dollars. What is his weekly allowance if he ended with 11 dollars?
Answer:
Weekly allowance $4
Step-by-step explanation:
Fred ended with $11. So, subtract $9 from washing the car.
$11 - $9 = $2
$2 Is the amount of weekly allowance Fred hasn't spent yet. However, at the beginning of the week, Fred used half his allowance. This means $2 was what was left. So,
$2 × 2 = $4
meaning Fred had $4 in allowance at the beginning of the week.

Answer:
$929.60
Step-by-step explanation:
step 1
Find the area of Lauren's bedroom
Remember that the area of a rectangle is equal to
[tex]A=LW[/tex]
so
[tex]A=(18)(12)=216\ ft^2[/tex]
step 2
Find the area of closet
Remember that the area of a rectangle is equal to
[tex]A=LW[/tex]
so
[tex]A=(2)(4)=8\ ft^2[/tex]
step 3
Find the total area
Adds the areas
[tex]216+8=224\ ft^2[/tex]
step 4
Find the cost
Multiply the total area by the cost per square feet
so
[tex]224(4.15)=\$929.60[/tex]
Final answer:
The cost to carpet Lauren's bedroom including her closet is found by calculating the total area and then multiplying by the carpet's cost per square foot. The total area is 224 square feet and with a carpet cost of $4.15 per square foot, the total cost is $930.40.
Explanation:
To calculate the cost to carpet Lauren's room and closet, we must first determine the total area that needs to be carpeted. We already know that the room measures 18 feet by 12 feet. Taking the square footage of the room, we perform a multiplication: 18 ft imes 12 ft = 216 square feet.
Next, we calculate the area of the closet separately, which measures 2 feet by 4 feet. The calculation would be 2 ft imes 4 ft = 8 square feet. Now, we add the area of the room and the closet to get the combined area: 216 sq ft + 8 sq ft = 224 square feet.
Lastly, we find the cost to carpet this combined area. The carpet costs $4.15 per square foot, therefore, we multiply the total area by the cost per square foot: 224 sq ft imes $4.15/sq ft = $930.40. So, the total cost to carpet Lauren's room and closet will be $930.40.

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.

Find the area of the circle if it has a circumference of 40
Answer:
127.39 square units
Step-by-step explanation:
We are given;
Circumference of the circle as 40 unitsWe are supposed to determine its area;
The circumference of a circle is given by;Circumference = πD or 2πr , where D is the diameter and r is the radius
Thus;
40 = 2πr
πr = 20
r = 20/π
Area of a circle is given by;
A = πr²
but, r = 20/π
Hence;
Area = π × (20/π)²
= π × 400/π²
= 400/π
Taking π to be 3.14
Area = 400 ÷ 3.14
= 127.39 square units
Thus, the area of the circle is 127.39 square units
