What is the vertex of f/x )=| x 8 |- 3?
The vertex of the graph of f(x) = |x + 8| - 3 is (-8, -3). It lies in the third quadrant.
Therefore the answer is (-8, -3).
Simplifying the given graph to the form f(x) = a|x - h| + k
f(x) = |x + 8| - 3
f(x) = 1 × |x + 8| - 3
where a = 1, h = -8, k = -3
So f(x) = |x + 8| - 3 is symmetrical about the line x = -8. At x = -8, y = -3.
Therefore, the vertex of the graph is (-8, -3).

What is factorisation of equations?Factorisation of equations is defined as the expression of a given equation as a product of several other factors.
From the equation given; x³ 4x² 11x 30. it's factorisation would be done by getting the first root by trial and error method∶
Since the sum of the coefficients is not zero, 1 is not a root
Let x = -2

The Brown’s family paid a total of $19.00 to bowl 3 games and rent shoes. Each game cost $4.00. Write an equation to represent the total cost y to rent shoes and bowl x games. How much is the shoe rental? How is this represented in the equation?
Answer:
Shoes rental cost: $7
The equation to find the cost is 19 = 4x + y
Step-by-step explanation:
Each game = $4
There are 3 games
They paid a total of $19.00
We have the equation to find the cost is
19 = 4x + y
Now let's put 3 in for x to solve for the cost of renting shoes!
19 = 4(3) + y
19 = 12 + y
y = $7
So, the equation to find shoe rental cost is 19 = 4x + y, and the cost to rent shoes is $7
Answer:
Step-by-step explanation:
19=4x+y is the equation .------1
here x is number of games.
y is cost to rent shoes.
it is given that x=3
so equation 1 becomes
19-12=y
so y=7

What is the value of the first quartile for observations 15 18 10 20 23 28 12 16?
The first Quartile of the given set of data is 13.5.
The value that splits a list of integers into quarters can be calculated with the help of the quartile formula. The information is separated into quartiles after being initially organized in ascending order. While quartiles divide data into four equal halves, the median divides it into two equal portions.
A set of observations can be divided into four equal halves using the quartile formula. Between the first term and the median is where the first quartile is located.
The quartiles are shown when the set of observations is organized in ascending order.
First Quartile (Q1) = ((n + 1)/4)thTerm
Given observations are
15, 18, 10, 20, 23, 28, 12,16
To find the First Quartile/Lower Quartile.
Arrange the given numbers in ascending order.
10, 12, 15, 16, 18, 20, 23, 28
Here there are 8 numbers
median is the = 4th term+5th term / 2 = 16+18/2 = 17
the median of the numbers below the median of the whole data set, 17. These numbers are 10,12,15,16. Since there are also an even number of numbers in this data set, the median is the average of its two middle numbers (12+15)÷2 = 27÷2 or 13.5.

a batch of 200 iron rods consists of 50 oversized rods, 50 undersized rods and 100 rods of the desired length. if two rods are drawn at random without replacement, what is the probability of obtaining (a) two rods of the desired length, (b) exactly one of the desired length, (c) none of the desired length? show all steps and clearly write out your formulas and assumptions
(a) The probability of obtaining two rods of the desired length is (100/200) * (99/199) = 0.495.
This can be found by using the formula for independent events:
P(A and B) = P(A) * P(B)
Since the two draws are of rods without replacement,
the probability of the first-rod being of the desired length = 100/200 (there are 100 desired-length rods out of a total of 200).
The probability of the second-rod being of the desired length = 99/199 (since one of the desired length rods has already been drawn). Multiplying these two probabilities gives us the answer.
(b)The probability of obtaining exactly one rod of the desired length
=(100/200) * (100/199) + (100/200) * (100/199)
= 0.990.
This can be found by using the formula for the union of two events: P(A or B) = P(A) + P(B).
Since the two draws are rods without replacement, the first draw has a probability of 100/200 of being of the desired length (there are 100 desired-length rods out of a total of 200).
The probability of the second draw being of the desired length is 100/199 (since one of the desired length rods has already been drawn). Adding these two probabilities gives us the answer.
(c) The probability of obtaining none of the desired length is (50/200) * (50/199) = 0.015.
This can be found by using the formula for independent events
: P(A and B) = P(A) * P(B).
Since the two draws are of rods without replacement, the probability of the first-rod being of the undersized length is 50/200 (there are 50 undersized rods out of a total of 200).
The probability of the second-rod being of the undersized length is 50/199 (since one of the undersized rods has already been drawn). Multiplying these two probabilities gives us the answer.

The equation that can be used to find the amount, v, Festive Features normally charges for a vest is given as follows:
12(v - 6) = 132.
How to obtain the normal price?
The normal price is obtained applying the proportions in this problem, considering the total amount paid and the number of items purchased.
The parameters are given as follows:
12 vests were purchased.The price of each vest was reduced by $6 from the normal price v, hence the discounted price is of v - 6.The total price was of $132.Then the equation used to find the standard price is presented as follows:

How many angles can you form when 2 parallel lines are cut by a transversal line?
When a transversal cuts two parallel lines, 8 angles are created.
When two lines do not cross one another, they are said to be parallel. In addition, parallel lines are two lines that cross each other at infinity.
A transversal line is one that crosses two other lines at two different locations. Line l meets a and b in the image below at two different locations, P and Q. Line l is the transversal line as a result.
Corresponding angles are those that are created when two parallel lines and a transversal intersect, also known as matching corners or corresponding corners.
∠1 and ∠6
∠4 and ∠8
∠2 and ∠5
∠3 and ∠7
When a transversal connects two coplanar lines, alternate interior angles are created.
∠4 and ∠5
∠3 and ∠6
However, each pair of alternate interior angles is equal if a transversal meets two parallel lines.
∠4 = ∠5
∠3 = ∠6
The pair of angles that are created on the outer side of two lines but on the other side of the transversal are known as alternate exterior angles.

The rule governing the ordering of variables is the commutative property. It states that the order of the variables does not influence the final answer when they are added or multiplied.

The associative feature of real numbers relates to grouping variables. It states that altering the grouping of variables added to or multiplied by one another has no effect on the output.
In mathematics, what is a distributive property?
This property states that multiplying the sum of two or more addends by a number yields the same result as multiplying each addend separately by the number and then putting the resulting products together.

If all three sets of comparable sides are present, the triangles are congruent.
Using congruence, the side-side-side shortcut can be used (SSS).

Natural numbers are a part of the number system, including all the positive numbers from 1 to infinity. Natural numbers are also called counting numbers because they do not include zero or negative numbers.
The median is the number in the middle of a list of numbers in ascending order, from lowest to highest.
The median is the middlemost element if the total number of elements in the list is odd, and the median is the average of the middlemost two values if the total number of elements in the list is even.
The list of the first 10 natural numbers is: 1,2,3,4,5,6,7,8,9,10
Here is the total number of elements in the list is even.
