The value of the inequality when the sum of two consecutive integers is less than -9 is x < - 5.
How to calculate the value?It is vital to note that an inequality simply shows that the expressions aren't equal.
In this case, the sum of two consecutive integers is less than -9.
Let the integers be x and x + 1.
Therefore, x + x + 1 < -9
2x + 1 < -9
Collect like terms
2x < -9 - 1
2x < -10
Divide
x < - 10 / 2
x < - 5
The value is x < - 5.

point A is located at (-2,-6) on the coordinate plane. Point A is reflected over the y-axis to create point A’. What ordered pair describes the location of A’?
The ordered pair coordinates of A' are (2, -6) if A is reflected over the y-axis.
What are transformations?The transformation, or f: X → X, is the name given to a function, f, that maps to itself. After the transformation, the pre-image X becomes the picture X. Any operation, or a combination of operations, such as translation, rotation, reflection, and dilation, can be used in this transformation. A function can be moved in one way or another using translation, rotation, reflection, and dilation. A function can also be scaled using rotation around a point.
The coordinates of A are (-2, -6).
Point A is reflected over the y- axis to create point A'
(x, y) → (-x,y)
A (-2, -6) → A' (- (-2), -6))
So, the coordinates of A' are (2, -6).

O CAB DC
OD AD BC
As per the reference attachment attached thereby along with the question statement, to prove the triangles ABC and ADC are congruent by SAS property, proving either of (AB ≅ CD), (AB ≅ DC) or (AD ≅ BC) will suffice.
In the reference attachment attached thereby along with the question statement, we are provided with two triangles, (ADC and ABC),
And as per the question statement, we are required to determine the relation between the corresponding sides or angles of the concerned triangles which we will need to prove over the information already provided in the figure, to ascertain that triangles ABC and ADC are congruent by SAS property.
Now, for two triangles to be congruent by SAS property, they will need to have two pairs of equal corresponding sides, and one set of equal corresponding angles.
Among our concerned triangles, ΔABC and ΔADC, already given that,
(∠DAC = ∠BCA), i.e., one set of equal corresponding angles,
And, (AC) is a common side to both ΔABC and ΔADC, i.e., one set of equal corresponding sides.
At this point, for ΔABC and ΔADC to be congruent, we will need to prove another set of corresponding sides to be equal, to complete SAS property.
Therefore, proving either of (AB ≅ CD), (AB ≅ DC) or (AD ≅ BC) will complete the second set of corresponding sides being equal, and (ΔABC and ΔADC) can be proved to be congruent triangles.

1. the following two points are located on a line (-12, 6). and (4,6), find the slope of the line.
2. Solve for the value of x : 2/8 = 3/x+2
thank you! this assignment is graded on accuracy so please try your hardest!!
The slope of the linear equation is 0, and the solution of the second equation is x = 10.
How to find the slope of the line?A general linear equation is written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
If the line passes through two points (x1, y1) and (x2, y2), then the slope is:
slope = (y2 - y1)/(x2 - x1)
So if the line passes through (-12, 6) and (4, 6), the slope is:
slope = (6 - 6)/(4 + 12) = 0
The slope is 0.
2) How to solve the equation for x?
Here we have the equation:
2/8 = 3/(x + 2)
If we move the denominators we get:
2*(x + 2) = 3*8
2x + 4 = 24
2x = 24 - 4
2x = 20
x = 20/2 = 10

The domain of y equals two divided by the quantity x minus three squared all minus one [y = (2)/(x - 3)² - 1] is: all real numbers.
What is a domain?In Mathematics, a domain can be defined as the set of all real numbers for which a particular function is defined.
This ultimately implies that, a domain is the set of all possible input numerical values or numbers (x-values) to a function and the domain of a graph comprises all the input numerical values which are located on the x-coordinate.
Translating the word problem into an algebraic equation, we have;
y = (2)/(x - 3)² - 1
When x = 3, we have:
y = (2)/(3 - 3)² - 1
y = 2/-1 = -2
When x = 1, we have:

What is the value of x in the given function?A function is simply a relationship that maps one input to one output.
Given the function in the question;
j( x ) = 3 - xj( x ) = -5x = ?To determine the value x or input value, equate the function to -5 and solve for x.
j( x ) = 3 - x
j( x ) = -5
-5 = 3 - x
Add 5 to both sides
-5 + 5 = 3 + 5 - x
0 = 8 - x

the wheels on Kiran's bike are 64 inches in circumference. How many times doo the wheels rotate if Kiran rides 300 yards ?
Answer:
169 times
Step-by-step explanation:
We know that the circumference of Kiran's bike wheel is 64 inKiran rides total distance of 300 yardsTo find number of rotations made by wheel...
Know that 1 yard = 36 in
300 yards = 36 x 300 = 10800 in
Number of rotation = Total distance covered by wheel ÷ Circumference of wheel
Number of rotations = 10800 ÷ 64 = 168.75 ≅ 169
Therefor, the wheel rotates = 169 times

When we are uncertain about the result of an event, we might discuss the probabilities of several outcomes—how likely they are. Statistics is the study of occurrences guided by probability. Probability is synonymous with possibility. It is a mathematical discipline that deals with the occurrence of a random event. The value ranges from zero to one. Probability has been introduced in mathematics to predict the likelihood of occurrences occurring. The probability is a measure of the possibility that an event will occur. It assesses the event's certainty. P(E) = Number of Favourable Outcomes/Number of Total Outcomes is the probability formula.

Using probability concepts, we calculated that the likelihood that the person plays the clarinet but not the flute is 0.2743.
What is conditional probability?The possibility of an event or outcome occurring based on the existence of a prior event or outcome is known as conditional probability. It is calculated by dividing the likelihood of the previous event by the likelihood of the subsequent, or contingent, event.
Here,
Finding people who can play the clarinet but not the flute is necessary. There are 172 people who can play the clarinet.
There are 47 people who can play both the clarinet and the flute.
As a result, 172-47=125 represents the number of people who can only play the clarinet and not the flute.
Probability(P),
P=( 125 / 350)
P=0.2743.
Therefore, the probability that a single person chosen at random can play clarinet but not flute is 0.2743.
