What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the statements are:-
x = 12, then 2x - 5 = 19.
2x - 5 = 19
(2 x 12 ) - 5 = 19
24 - 5 = 19
19 = 19
If 2x - 5 = 19, then x = 12. The value of x will be calculated as,
2x - 5 = 19
2x = 19 + 5
2x = 24
x = 24 / 2
x = 12

What's the mode of data?
A mode is defined as the value that has a higher frequency in a given set of values. It is the value that appears the most number of times.
In statistics, the value that consistently appears in a particular collection is referred to as the mode. The mode or modal value in a data collection is sometimes referred to as the value or number that occurs most frequently in the data set. In addition, to mean and median, it is one of the three measures of central tendency.
For example, the mode of the set {3, 7, 8, 8, 9}, is 8. Therefore, for a finite number of observations, we can easily find the mode. A set of values may have one mode or more than one mode or no mode at all.

what is the conjugate of [tex]x+\sqrt{y}[/tex]
By using the concept of conjugate, it can be calculated that
Conjugate of [tex]x + \sqrt{y}[/tex] is [tex]x - \sqrt{y}[/tex]
What is conjugate?
Conjugating is the process of changing a verb in a sentence to match the person, number, gender, tense, mood, and voice of the subject. For example, the verb "to walk" changes to "walked" when conjugated in the past tense. Conjugation is important in many languages, including English, as it helps to make communication more precise. Conjugation involves making changes to the base form of the verb, such as adding suffixes or prefixes, or changing the spelling of the word. Different languages have different rules for conjugating verbs, so it is important to understand the language’s system of conjugation before attempting to use it.

Lydia owns. Good truck that sells tacos and burritos. She only has enough supplies to make 115 tacos or burritos. She sells each taco for $4 and each burrito for $6.75. Lydia must sell at least $680 worth of tacos and burritos each day. If tacos were sold, determine the minimum number of burritos that Lydia must sell in order to meet the requirements.
Answer and Step-by-step explanation:
Lydia must sell at least $680 worth of tacos and burritos each day, and she only has enough supplies to make 115 tacos or burritos. If she sells each taco for $4, then she can make a maximum of 115 tacos * $4/taco = $<<115*4=460>>460 by selling tacos.
Therefore, in order to make at least $680, Lydia must sell burritos in addition to the tacos. The minimum number of burritos she must sell in order to make at least $680 is $680 - $460 = $<<680-460=220>>220.
Since Lydia sells each burrito for $6.75, she must sell at least $220 / $6.75/burrito = <<220/6.75=32.5>>32.5 burritos to make at least $680. Since she only has enough supplies to make 115 tacos or burritos, and she has already accounted for 115 tacos, she must sell a minimum of 32.5 burritos to meet the requirements.

You want the measures of the numbered angles in the figure comprised of overlapping right triangles.
Complementary anglesThe acute angles in a right triangle are complementary, as are the two angles into which a right angle is divided.
∠1 +35° = 90° ⇒ ∠1 = 55°
∠3 +35° = 90° ⇒ ∠3 = 55°
Exterior angleThe angle marked 70° is exterior to the bottom right triangle, so is equal to the sum of angles 3 and 4.
∠3 +∠4 = 70°
55° +∠4 = 70° ⇒ ∠4 = 15°
Angle 2 is the other acute angle in the bottom right triangle, so ...
∠2 = 90° -∠4 = 90° -15°
∠2 = 75°
What are the 3 types of rational functions?
Rational functions can have 3 types of asymptotes:
1. Horizontal Asymptotes
2. Vertical Asymptotes
3. Oblique Asymptotes
The ratio of two polynomial functions with a non-zero denominator is known as a rational function.
1. Horizontal Asymptotes:
A graph's horizontal asymptote is a horizontal line with the equation y = b, and when the inputs get closer to 0 or 1, the graph moves toward the line. A graph's slant asymptote is a sloped line, denoted by the equation y = mx + b, where the graph slopes toward the line when the inputs approach 0 or -1.
2. Vertical Asymptotes:
Vertical asymptotes are vertical lines that represent the zeros in a rational function's numerator. Asymptotes can also occur in other situations, such as logarithms, although you'll almost probably run into them when discussing rationals for the first time.
3. Oblique Asymptotes:
These slanted asymptotes, known as oblique asymptotes, demonstrate how a function rises or falls without bound. Slant asymptotes are another name for oblique asymptotes. The slant asymptote won't be a line because the degree of the numerator is 3 and the degree of the denominator is 1, respectively.

We will write greater than 20 using Inequality sign as ( > 20).
The first number in every inequality sign tells us how the first and second numbers relate to one another, so > 20 means "A number is greater than 20."
In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to one another.
Greater than and less than symbols are used to indicate whether one number is greater than or less than another. The greater than symbol (>) is used when the first number exceeds the second number. The less than symbol (<) is used when the first number is less than the second number.

How do you write 8 or more?
We can write '8 or more' as [tex]\geq 8[/tex], using the greater-than equal to sign.
The greater-than sign is a mathematical symbol that denotes an inequality between two values. The widely adopted form of two equal-length strokes connecting in an acute angle at the right, >, has been found in documents dated as far back as 1631. In mathematical writing, the greater-than sign is typically placed between two values being compared and signifies that the first number is greater than the second number.
Examples of typical usage include 1.5 > 1 and 1 > −2. The less-than sign and greater-than sign always "point" to the smaller number. Since the development of computer programming languages, the greater-than sign and the less-than sign have been repurposed for a range of uses and operations.
Here, we can use an alternate to the 'greater-than' symbol: a 'greater-than equal to' symbol, denoted as ≥.

The point (2, -3) is the midpoint of segment JK .
Point K is located at (-6, -3).
What is the length of segment JK ?
The required length of line segment JK would be 16 units.
The midpoint of a line segment is the point that divides the line segment into two equal parts. So, to find the length of the line segment JK, we can first find the coordinates of point J, which is the other endpoint of the line segment.
Let the coordinate of the point J would be (x, y)
Since the midpoint of the line segment is (2, -3), and point K is located at (-6, -3), we can use the midpoint formula to find the coordinates of point J:
2 = (x+(-6))/2 ; -3 = (y+(-3))/2
4 = x - 6 ; -6 = y -3
x = 10 ; y = -3
So the coordinate of the point J :(10, -3)
Now that we have the coordinates of both endpoints of the line segment, we can use the distance formula to find the length of the line segment:
length = √((10 - (-6))² + (-3 - (-3))²)
= √((10 + 6)² + (-3 + 3)²)
= √(16² + 0)
= √(256)
= 16

What is P(A or B)?
From the concept of algebra of venn diagram we obtain that
P(A or B) = 0.75.
A set is a collection of well-defined objects.
A subset contains all the elements or few elements of the given set.
The improper subset is when it contains all the elements of the given set and the proper subset is when it doesn't contain all the elements of the given set.
From set theory, we know that N(A∪B) = N(A) + N(B) - N(A∩B).
It states that N(A) or N(B) is the sum of N(A) and N(B) minus the common intersecting region N(A∩B) as we have already considered the region in the sum of N(A) and N(B) twice.
Similarly, P(A or B) = P(A) + P(B) - P(A∩B)>
Therefore, P(A or B) = 0.50 + 0.40 - 0.15.
P(A or B) = 0.90 - 0.15.
