Part 1: Use the graph to count the slope of the line that passes through the points (2, 1) and (2, 0).
Part 2: In two or more complete sentences, explain why it is not possible to write the equation of the given line in the traditional version of the point-slope form of a line.
Answers
Not 100% how to do part 2, but here's my answer:
The slope would be 1/0 , and that's not possible cause you can't have 0 in the denominator. That's why it's not possible and the slope is undefined.
Answer:
Notice that the given line is vertical, which means its slope is undetermined.
We can demonstrate that using the slope definition:
[tex]m=\frac{y_{2} -y_{1} }{x_{2}-x_{1} }[/tex]
[tex]m=\frac{1-0}{2-2}=\frac{1}{0}=IND[/tex]
Which is undetermined because null denominators cannot be determined.
Now, the Point-Slope form of a line refers to expressin the equation with one point and its slope. So, if we cannot determine the slope, we cannot determine the point-slope form neither. In other words, we need to have a determined slope to express it in this form.

Normally I am not one to make long answers
but if you want an explanation in case you have the same question with different numers, here is an explanation
Plug in the eequation and solve for x
Doing quick math the equation would be 8y-33 = 5y+9
I plugged this into m a t h w a y and got y=14
Then I subsituted y with 14
5 x 14 = 70 70 + 9 =79
Then I did a double check by making sure they were both equal
8 x 14 = 112 112 - 33 = 79
79 = 79
Therefore your answer is 79
Hope this helped, have a great day :)

PLEASE HELP!!!!! How does “rationalizing the denominator” use the form of 1?
Answers
For an example, let's take the fraction 1/√2. We call √2 irrational because it cannot be expressed as a ratio of two integers. Oftentimes when we have irrational numbers like √2 in the denominator, it helps to perform a little bit of algebraic manipulation on them to make the denominator rational. Here's where that "form of 1" comes in. Remember that, as a rational number, 1 can be expressed as n/n, where n is any number. We can use this fact to rationalize the denominator of 1/√2 by multiplying it by √2/√2, which is equivalent to 1.
When we multiply the two together, we get:
[tex] \frac{1}{\sqrt{2}}\cdot \frac{\sqrt{2}}{\sqrt{2}}= \frac{\sqrt{2}}{(\sqrt{2})^2}= \frac{\sqrt{2}}{2} [/tex]
Crucially, multiplying by 1 in the form of √2/√2 keeps the fraction's value the same, since 1 times any number just equals that same number. If we weren't multiplying but some form of 1, we'd change the number entirely, making the whole attempt at rationalizing the denominator pointless.

All the Factor of 40
Answers
1,2,4,5,7,10,20,40
The factors of 40 are whole numbers that divide 40 without a remainder, including 1, 2, 4, 5, 8, 10, 20, and 40.
To find all the factors of 40, you need to identify all the whole numbers that can divide 40 without leaving a remainder. The factors of 40 are numbers that multiply together to give the product of 40. Here's how we can find them:
List the number 1 and the number itself (which is 40) because 1 and 40 are always factors of 40.Try dividing 40 by whole numbers starting from 2 onwards.If the division does not leave a remainder, then the divisor is a factor of 40.Repeat this process with increasing numbers until you reach the square root of 40Therefore, the factors of 40 are: 1, 2, 4, 5, 8, 10, 20, and 40.
A private plane leaves the airport and flies 1.3 hours at 110 mph on a bearing if 40 degrees. Then it turns and continues another 1.5 hours at the same speed, but in a bearing if 130 degrees. Through what angle did the plane have to turn to head back to the airport?
Answers
The first distance traveled is
a = (110 mi/h)*(1.3 h) = 143 mi
The second distance traveled is
b = (110 mi/h)*(1.5 h) = 165 mi
From geometry,
x = 40°
y = 180° - 130° = 50°
x + y = 40° + 50° = 90°
Therefore we have a right triangle.
By definition
tan θ = 165/143 = 1.1538
θ = tan⁻¹ 1.1538 ≈ 49°
Because the sum of angles in a triangle is 180°, therefore
z = 180° - (49° +90°) = 41°
The angle through which the plane has to turn to head back to the airport is
φ = 360° - (y + z)
= 360° - (50° + 41)°
= 269°
Answer: 269°

Step-by-step explanation:
Given: △ABC≅△JKL,
m∠B=55°, and m∠L=25°
We know that if two triangles are congruent then their corresponding angles are equal.
∴ m∠A=m∠J
m∠B=m∠K=55°
m∠C=m∠L=25°
Now, by angle sum property in triangle JKL we have

Find two numbers whose difference is 168 and whose product is a minimum
Answers
The two numbers whose difference is 168 and whose product is a minimum will be -50 and 50.
What is the equation?An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.
It is given that, two numbers whose difference is 168 and whose product is a minimum.
Suppose the two numbers are x and Q respectively.
If x - Q = 100, then Q = 100 + x
The function of their product is minimum,
F(x) = xQ
F(x) = x (100 + x)
F(x) = x² + 100x
Find the equation's lowest point on a graph. At x, the lowest point is -50,
f(x) = -2500
If,
Q = 100 + x
Q = 100 + (-50)
Q= 50
The product of the number is,
xQ = 50 × -50
xQ = -2500
Thus, the two numbers whose difference is 168 and whose product is a minimum will be -50 and 50.

If two angles share a vertex then they are adjacent true or false
Answers
The given statement is true"If two angles share a vertex then they are adjacent".
What is an angle?When two lines or rays converge at the same point, the measurement between them is called an "Angle."
If two angles in geometry share a side and a vertex, they are said to be adjacent. In other words, consecutive angles do not overlap and are placed side by side.
When an angle's vertex and side are shared by another angle, the two angles are said to be adjacent angles. The vertex of an angle is the point where the rays come to a stop and form the sides of the angle. When two adjacent angles share a vertex and a side, they can be either complementary or supplementary angles.
Thus, the given statement is true"If two angles share a vertex then they are adjacent".

is the line through points P(1,9) and Q(9,6) perpendicular to the line through points R(-6,0) and S(-9,8)? Explain?
Answers
To determine if two lines are perpendicular, we can calculate their slopes. The line through P(1,9) and Q(9,6) has a slope of -3/8, and the line through R(-6,0) and S(-9,8) has a slope of -8/3. The product of these slopes is -1, indicating that the lines are perpendicular.
Explanation:To determine whether the line through points P(1,9) and Q(9,6) is perpendicular to the line through points R(-6,0) and S(-9,8), we can calculate the slope of each line. The slope of a line passing through two points (x1, y1) and (x2, y2) is given by the formula: slope = (y2 - y1) / (x2 - x1).
For the line through P(1,9) and Q(9,6), the slope is (6 - 9) / (9 - 1) = -3/8.
For the line through R(-6,0) and S(-9,8), the slope is (8 - 0) / (-9 - (-6)) = 8/-3 = -8/3.
If the two lines are perpendicular, the product of their slopes should be -1. Let's check: (-3/8) * (-8/3) = 1. Therefore, the line through points P(1,9) and Q(9,6) is perpendicular to the line through points R(-6,0) and S(-9,8).

A movie theater sells student tickets for $5 and adult tickets for $10. On Saturday night, 2,500 people go to the theater and ticket sales total $18,000. How many adults and children went to the theater on Saturday night? Which solution is reasonable? A) 2000 students and 1000 adults B) 1100 adults and 1400 students C) 3000 students and 0 adults D) 500 students and 1500 adults
Answers
Answer is B because 1100 + 1400 = 2500
The reasonable solution is B) 1100 adults and 1400 students, as it satisfies both attendance and revenue criteria.
Consider a movie theater that sells student tickets for $5 and adult tickets for $10. On a Saturday night, 2,500 people attended the theater, and the total ticket sales amounted to $18,000. The goal is to determine the number of adults and students who attended, with multiple choices provided:
We can set up two equations to represent the information:
The total number of people who attended: S + A = 2500
The total ticket sales amount: 5S + 10A = 18000
Solving this system of equations gives the correct solution:
B) 1100 adults and 1400 students.
This solution satisfies both equations (S + A = 2500 and 5S + 10A = 18000). It is reasonable as it accounts for both students and adults attending, and the total revenue aligns with the given information. The number of students (1400) and adults (1100) adds up to the total attendance of 2500.
