which ordered pairs are solutions to the inequality y− 4x ≥−5 ?
Select each correct answer.
(4, 0)
(1, −1)
(−4, 2)
(−2, 1)
(5, −2)
The x-intercept of the line −6x+3y=18.9 is −3.15, and the y-intercept is 6.3. The point-slope form of the line with slope −14 passing through (-2, 9) is y−9=−14(x+2). The ordered pairs that solve the inequality y∓4x≥−5 are (1, −1), (−4, 2), and (−2, 1).
Explanation:To find the x-intercept and y-intercept of the line described by the equation −6x+3y=18.9, we can set each variable to zero in turn and solve for the other:
For the x-intercept, set y = 0:Therefore, the x-intercept is −3.15 and the y-intercept is 6.3.
For the point-slope form of the line with slope −14 that passes through the point (−2, 9), we use the formula y – y1 = m(x – x1), where m is the slope and (x1, y1) is the point the line passes through. This gives us:
y – 9 = −14(x – (−2)) → y – 9 = −14(x + 2)
The correct option is C. y – 9 = −14(x + 2).
To determine which ordered pairs are solutions to the inequality y – 4x ≥ −5, we test each pair by substituting the x and y values into the inequality:
(4, 0): −4 – 4(4) ≥ −5 → −4 – 16 ≥ −5 is false.(1, −1): −1 – 4(1) ≥ −5 → −1 – 4 ≥ −5 is true.(−4, 2): 2 – 4(−4) ≥ −5 → 2 + 16 ≥ −5 is true.(−2, 1): 1 – 4(−2) ≥ −5 → 1 + 8 ≥ −5 is true.(5, −2): −2 – 4(5) ≥ −5 → −2 – 20 ≥ −5 is false.The ordered pairs that are solutions to the inequality are (1, −1), (−4, 2), and (−2, 1).

What is the most precise classification of the quadrilateral?

The most precise classification of the quadrilateral defined by the points F(-13, 7), I(1, 12), N(15, 7), and E(1, -5) is a kite.
What is a quadrilateral?Any closed figure made by 4 line segments joined end to end in series is called a quadrilateral. That quadrilateral in which opposite sides are parallel is called a parallelogram.
Thus, a parallelogram is always a quadrilateral but a quadrilateral can or cannot be a parallelogram.
We are given that;
The points F(-13, 7), I(1, 12), N(15, 7), E(1, -5)
Now,
To determine the most precise classification of the quadrilateral defined by the points F(-13, 7), I(1, 12), N(15, 7), and E(1, -5), we need to use the properties of quadrilaterals and their classifications.
One way to classify a quadrilateral is by its sides and angles. Based on this classification, the quadrilateral can be classified as a kite. A kite is a quadrilateral with two pairs of adjacent sides that are equal in length, and the diagonals of a kite are perpendicular.
To see why the quadrilateral defined by F, I, N, and E is a kite, we can start by noting that FI and EN have equal length, as do IN and FE. Additionally, we can compute the lengths of the diagonals and check whether they are perpendicular.
The length of diagonal FN is sqrt(676+25)=sqrt(701), and
The length of diagonal IE is sqrt(256+49)=sqrt(305).
The product of the slopes of FI and EN is (12-7)/(1-(-13))*(1-(-5))/(1-15)=-5/4. This product is negative, indicating that the diagonals are perpendicular.
Therefore, the quadrilateral defined by F, I, N, and E is a kite.

Step-by-step explanation:
The area of a rectangle is 44 ft2 , and the length of the rectangle is 3 ft less than twice the width. find the dimensions of the rectangle.
Final answer:
To find the dimensions of a rectangle where the length is 3 ft less than twice the width and the area is 44 ft², we use the relationship between the width and length to set up a quadratic equation. After solving for the width, we use that width to find the length and confirm that the area is correct.
Explanation:
To find the dimensions of the rectangle with an area of 44 ft2, we need to set up an equation based on the given relationships. Let's denote the width of the rectangle as w and the length as l. According to the problem, the length is three feet less than twice the width, so we have l = 2w - 3. The area of the rectangle is the product of its width and length, so the equation to calculate the area is w × l = 44. Substituting the expression for l into this equation yields w × (2w - 3) = 44.
Solving this quadratic equation, we distribute the width and get 2w2 - 3w = 44. By moving all terms to one side, we have 2w2 - 3w - 44 = 0. Factoring the quadratic equation or using the quadratic formula will result in two values for w, where one will be the width and the corresponding l will be the length when plugged into l = 2w - 3.
Let's find the dimensions:
Width: wLength: 2w - 3Once the values are calculated, we can confirm that the width and length provide an area of 44 ft2.
Therefore, the width of the rectangle is w= 5.5 feet.
Now, we can find the length (l):
l=2w−3=2(5.5)−3=11−3=8
So, the length of the rectangle is l=8 feet.

[tex]f(2) = -3(4)-4[/tex]
[tex]f(2) = -12-4[/tex]
[tex]f(2) = -16[/tex]
B. [tex]g(x) = 4(x+3)^2-68[/tex]
[tex]g(2) = 4(2+3)^2-68[/tex]

[tex]g(2) = 4(25)-68[/tex]
[tex]g(2) = 100-68[/tex]
[tex]g(2) = 32[/tex]

[tex]j(2) = 2(2)-62[/tex]
[tex]j(2) = 4-62[/tex]
[tex]j(2) =-58[/tex]
Option B -[tex]g(x) = 4(x+3)^2-68[/tex] gave you the result [tex]g(2) = 32[/tex]

A set of data that is made up of two paired variables is
Final answer:
A set of data that is made up of two paired variables is called bivariate data. These types of data reflect a one-to-one relationship between the paired variables and can be visualized using graphs with independent and dependent variables.
Explanation:
The set of data made up of two paired variables is known as bivariate data. This type of data includes pairs of related data where each data point in one set is matched with exactly one data point in the other set, establishing a one-to-one relationship between the two. Essentially, in a paired data set, both data sets are the same size, and there's an explicit connection between each point in one set to one in the other.
A common way to visualize the relationship between two properties of a system is by using a two-dimensional data plot. This graph will typically have two axes: a horizontal axis for the independent variable (often represented as 'x'), and a vertical axis for the dependent variable (often represented as 'y'). For example, if we know a relationship such as y = x² + 2, we can create a table of x and y values and then graph them to visualize the relationship.
When dealing with categorical variables, data is often represented in a two-way table, which is also based on bivariate data. In such a table, entries in the total row and total column are called marginal frequencies or marginal distributions.

A mail-order supplier of small electrical parts charges a shipping fee of $8, plus $5 for each pushbutton light switch ordered. If x is the number of pushbutton switches ordered, then the expression for the total cost of an order is 5x + 8 What is the total cost of six switches?
Answer:
B. Number of switches
x. 5x + 8
1. 13
2. 18
3. 23
Final answer:
The expression for the total cost of an order with x pushbutton switches is 5x + 8. For six switches, it amounts to 5(6) + 8, or $38.
Explanation:
The total cost of ordering a certain number of switches can be determined by the expression 5x + 8, where x is the number of pushbutton switches ordered. In this instance, to find the total cost for six switches, we substitute x with 6. Therefore, the calculation would be 5(6) + 8.
Calculating this, we get:
5(6) = 30Total cost = 30 + 8 = $38Thus, the total cost for ordering six switches is $38.

Part 1:Is it possible for a composite number to have more than one prime factorization? Is it possible for a number to have no prime factors? Why? Part 2: Give an example of how prime factorization could be used in the real world. Part 3: View and comment on the work of at least two other students. Explain why you agree or disagree with their ideas.
A composite number has only one prime factorization, and 1 is the only number without prime factors. Prime factorization plays a crucial role in cryptography. Peer work review would focus on understanding and accuracy but cannot be provided without specific student examples.
No, a composite number cannot have more than one prime factorization due to the Fundamental Theorem of Arithmetic, which states that every integer greater than 1 either is a prime number itself or can be factored into prime numbers in exactly one way, ignoring the order of the factors. On the other hand, the only number that has no prime factors is 1, as it is neither prime nor composite.
One real-world application of prime factorization is in cryptography, particularly in algorithms like RSA, which is used to secure data transmission over the internet. The difficulty in factoring large numbers into primes is what makes this method effective for encrypting sensitive information such as credit card numbers.
Without specific examples of the work of other students, it is not possible to provide a review. Typically, when reviewing peer work, one would assess the correctness of their understanding of prime factorization and its application in real-world scenarios, as well as the clarity and accuracy of their explanations.

The cross-section of a beehive reveals it is made of regular hexagons. What is the measure of each angle in the regular hexagon ?
Each angle in a regular hexagon measures 60 degrees.
Explanation:A regular hexagon is a polygon with six equal sides and six equal angles. Since the cross-section of a beehive is made of regular hexagons, each angle in the regular hexagon would have the same measure.
To find the measure of each angle in the regular hexagon, we can use the formula:
Measure of each angle = (360 degrees) / (number of sides)
Substituting the value for a regular hexagon, we have:
Measure of each angle = (360 degrees) / (6 sides)
Therefore, each angle in a regular hexagon measures 60 degrees.
