25 POINTS!! ANSWER FOR BRAINLIST AND SHOW WORK!!!
Answer:
See attached "Image 2" for graph
3 points that are in the system
[tex](6,1)\\(8,-2)\\(7,5)[/tex]
3 points that are not in the system:
[tex](0,0)\\(-2,-6)\\(-8,4)[/tex]
Step-by-step explanation:
Start by writing the equation in slope-intercept form so they can be graphed.
[tex]\left \{ {{y+5 < 2x} \atop {3y\geq -2x+6}} \right. \\\\\left \{ {{y < 2x-5} \atop {y\geq -\frac{2}{3} x+2}} \right. \\\\[/tex]
Now, graph just the lines - LIGHTLY- on the coordinate plane. See the first attached image.
Now, you can shade the correct areas. In the first equation y is LESS THAN the function, so you would shade BELOW the line, and draw the line as a dashed line, not a solid line. This is because y is not EQUAL to the function.
In the second equation y is GREATER than or EQUAL to the function, so draw the line as a solid line and you would SHADE above the line.
In a system of inequalities, the correct area to shade is where the two shaded areas overlap. See the attached image 2 to see how that looks.
Some points that are in the system of inequalities are:
[tex](6,1)\\(8,-2)\\(7,5)[/tex]
These points are NOT in the system:
[tex](0,0)\\(-2,-6)\\(-8,4)[/tex]

determine if the following orders pairs
The given ordered pair (x, y) represents a linear function
Consider first point (-1, -3) and (0, -1)
The slope of the line is the change in y coordinate with respect to the change in x coordinate of the line.
The slope of the line = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Substitute the value in the equation
The slope of the line = (-1-(-3)) / (0 -(-1)
= (-1+3) / 1
= 2
Consider the next set of points (1, 1) and (2, 3)
The slope of the line = (3-1) / (2-1)
= 2
Here slope of the line is same, therefore it is linear function
Hence, the given ordered pair (x, y) represents a linear function

the standard deviation of utterance is the average number of morphemes that communicators use in their sentences. true or false
The statement which said that "the standard deviation of utterance is the average number of morphemes that communicators use in their sentences", is false.
What is the standard deviation?
Standard deviation is a statistical value that shows the distribution of data in the sample so that it can show how close each point is to the sample mean value. The amount of data that differs from the average can be identified by the standard deviation value.
In conclusion, the standard deviation of utterance is the number of morphemes that are different from the average morpheme used by the communicator in his sentence.

consider the equation y+4=-1/2(x+8)
The equation of the line in standard form is x + 2y = -16
What are linear equations?Linear equations are the set of equations that have constant slopes or gradient
How to put the equation of a line into standard form?From the question, we have the following equation that can be used in our computation:
y+4=-1/2(x+8)
Rewrite the above equation properly
So, we have the following representation
y + 4 = -1/2(x + 8)
Multiply through the equation by -2
So, we have the following equation
-2(y + 4) = -1/2(x + 8) * -2
Evaluate the products
-2y - 8 = x + 8
To rewrite as standard form is to make the variable stand alone
So, we have
-x -2y = 8 + 8
Evaluate the like terms
So, we have the following representation
-x -2y = 16
Multiply through by -1
x + 2y = -16
Hence, the equation is x + 2y = -16

The width of the shade along line AB, using relations in a right triangle, is of:
337.8 mm.
What are the relations in a right triangle?There are three relations in a right triangle, given as follows:
The sine of an angle of the triangle is represented by the length of the opposite side to the angle divided by the length of the hypotenuse.The cosine of an angle of the triangle is represented by the length of the adjacent side to the angle divided by the length of the hypotenuse.The tangent of an angle of the triangle is represented by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.The width of the shade along-side line AB is of:
100 mm + e1 + e2.
Considering a bisection at the top corner of the shade, we have that:
e1 is the length opposite side to an angle of 50º in a right triangle with hypotenuse of 150 mm, hence:
sin(50º) = e1/150
e1 = 150 x sin(50º)
e1 = 114.9 mm.
Considering a bisection at the bottom corner of the shade, we have that:
e2 is the length opposite side to an angle of 55º in a right triangle with hypotenuse of 150 mm, hence:
sin(55º) = e2/150
e2 = 150 x sin(55º)
e2 = 122.9 mm.
Hence the total width of the shade is of:
100 mm + e1 + e2 = 100 + 114.9 + 122.9 = 337.8 mm.

If the average product of labor is seven units of output per worker per day, the total output of 15 workers will be ______________ units per day.
The total output of 15 workers will be 105 units per day.Work and time are correlated so using this we could solve the question.
What is work and time?
Time is the duration of any activity or work that occurs or continues.
Work is a task or set of activities designed to achieve a specific result.
Main Body:
This can be done by simply multiplying both number of days and total work in one day.Hence the equation become:
total output = total workers*total work done by one person.
Total output = 7*15
hence,total output = 105 units

What is the main difference between vulnerability scanning and penetration testing?.
The main difference between vulnerability scanning and penetration testing is a vulnerability scan is an automated, high-level test that looks for and reports potential vulnerabilities. A penetration test is a detailed hands-on examination by a real person that tries to detect and exploit weaknesses in your system.
vulnerability scanning:
These scans are typically automated and give a beginning look at what could possibly be exploited.
High-quality vulnerability scans can search for over 50,000 vulnerabilities and are required as per PCI DSS, FFIEC, and GLBA mandates.
penetration testing:
A penetration test simulates a hacker attempting to get into a business system through hands-on research and the exploitation of vulnerabilities. Actual analysts, often called ethical hackers, search for vulnerabilities and then try to prove that they can be exploited. Using methods like password cracking, buffer overflow, and SQL injection, they attempt to compromise and extract data from a network in a non damaging way.

A -12,5
B-12, -5,5

D-5, 5, 12
For the given function f(x) = 5x² - 35x -300 the rational zeroes of the given function are 12 and -5.
As given in the question,
Given function is equal to:
f(x) = 5x² - 35x -300
Simplify the given function f(x) = 5x² - 35x -300 to get the rational zeros of the function,
f(x) = 0
⇒ 5x² - 35x -300 = 0
⇒ 5( x² - 7x - 60) = 0
As 5≠ 0 ,
⇒ x² - 7x - 60 = 0
⇒ x² - 12x + 5x- 60 = 0
⇒(x-12) (x+ 5) = 0
⇒ x = 12 or -5
Therefore, for the given function f(x) = 5x² - 35x -300 the rational zeroes of the given function are 12 and -5.

You have differentiable functions f and g that are inverses of each other with ...
f(7) = -4f'(7) = 2g(-4) = 7and you want to know g'(-4).
SolutionConsider the composition ...
f(g(x)) = x . . . . . . the functions are inverses of each other.
Differentiating with respect to x, we get ...
f'(g(x))·g'(x) = 1
g'(x) = 1/f'(g(x)) . . . . . . divide by the coefficient of g'(x)
For x = -4, this is ...

The equation could be used to solve for charles' rate if it is represented by x is 2x=54.
In the given question wehave to find the equation could be used to solve for charles' rate if it is represented by x.
Bill riding a bicycle at an average rate of 9 mph.
Charles' rate is x.
So the relative rate = x−9 mph
Distance traveled by Bill in 4 hours = 9*4 =36 mph
Charles' overtook Bill in 2 hours. So
Relative Rate = Distance/Time
x−9=36/2
Multiply by 2 on both side. We get
2(x−9)=36
Simplifying
2x−18=36
Add 18 on both side, we get
2x=36+18
2x=54
Hence, the equation could be used to solve for charles' rate if it is represented by x is 2x=54.
