Which word describes the slope of the line?
positive
negative
zero
undefined
Answers
Answer:
positive
Step-by-step explanation:
The slope is the inclination of the line with respect to the x-axis. It is denoted by the letter [tex]m[/tex]. In mathematical language, the slope [tex]m[/tex] of the line is defined as the difference on the y-axis divided by the difference on the x-axis for two different points [tex]P_1(x_1,y_1)[/tex] and [tex]P_2(x_2,y_2)[/tex] on the line:
[tex]m=\frac{\Delta y}{\Delta x} =\frac{y_2-y_1}{x_2-x_1}[/tex]
If:
[tex]m>0[/tex] The slope is positive and the line is increasing from left to right[tex]m<0[/tex] The slope is negative and the line is decreasing from left to rightIf a line is vertical the slope is undefined[tex]m=0[/tex] is a constant function.
Since the graph of the linear function shown is increasing from left to right, we can conclude that the slope is positive.

Kevin and Brittany write an equation to represent the following relationship, and both students solve their equation.
And, condition is given as,
5 times the difference of a number and 20 is the same as half the sum of 4 more than 4 times a number.
What is linear equation?
A linear equation only has one or two variables. No variable in a linear equation is raised to a power greater than 1.
Now, according to given condition,
5 times the difference of a number and 20 is written as,
[tex]5 ( x - 20 )[/tex]
And, half the sum of 4 more than 4 times a number, is written as
[tex]\frac{1}{2} ( 4x + 4)[/tex]
Now, both equation are equal
[tex]5 ( x - 20 ) = \frac{1}{2} ( 4x + 4)\\5x - 100 = 2x + 2\\3x = 102\\x = 34[/tex]
Hence, Kelvin found the correct equation and solution.

Michael has a total of$4.40 in dimes (1 dime=$0.10) and quarters (1quarter=$0.25), and he has 20 coins in total. Which of the following systems of equations can be used to find the number of dimes, d, and the number of quarter,q, he has?
Answers
0.1d+0.25q=4.40 Let's just read what this says: first, # of dimes (d) plus # of quarters (q) is 20.The second equation can be called the VALUE EQUATION; it says that one tenth of a dollar ($0.10) times the # of dimes is part of the total monetary value, and that one quarter of a dollar ($0.25) times the # of 'quarter' coins is the other part of this stash, and it totals $4.40. VOTE FOR A.
Final answer:
To solve for the number of dimes and quarters Michael has, we use two equations: 0.10d + 0.25q = 4.40 for the total value, and d + q = 20 for the total quantity of coins.
Explanation:
To find the number of dimes, d, and the number of quarters, q, Michael has, we need two equations to form a system. The first equation will represent the total amount of money in terms of dimes and quarters, and the second one will represent the total number of coins.
The value of a dime is $0.10 and the value of a quarter is $0.25. The total amount of money, $4.40, can be represented as 0.10d + 0.25q = 4.40. This is the value equation.
Since there are 20 coins in total, the second equation will simply be the count of both types of coins together: d + q = 20. This is the quantity equation.
The system of equations to find the number of dimes and quarters is:
0.10d + 0.25q = 4.40 (value equation)
d + q = 20 (quantity equation)

A work shift for an employee at a restaurant consists of 10 hours. What fraction of the employee's work shift is represented by 6 hours?
Answers
Final answer:
To calculate the fraction of a 10-hour shift that 6 hours represents, you divide 6 by 10 and simplify the resulting fraction, which is 6/10, to 3/5. Therefore, 6 hours is 3/5 of the work shift.
Explanation:
If an employee works a 10-hour shift, and you want to find out what fraction of the shift is represented by 6 hours, you divide 6 by the total hours in the shift which is 10. So, we write this as the fraction 6/10.
Now, simplifying the fraction, both the numerator (6) and the denominator (10) can be divided by 2. This gives us 3/5. Therefore, 6 hours represent 3/5 of the employee's 10-hour work shift.
To relate this to a concept you might already be familiar with, consider that 60 minutes make up 1 hour. If we write this as a ratio, it would be 60 minutes / 60 minutes, which simplifies to 1. Similarly, when we talk about fractions of an hour, like in the question, we're essentially looking for the number of parts of the shift that are being taken up by 6 hours in a 10-hour slot, which is 3/5.

x = measure of angle TAP
y = measure of angle BRE
We're told that "angle BRE is its own complement" meaning that angle BRE added to itself is 90 degrees. In algebraic terms, we can say
y+y = 90
2y = 90
2y/2 = 90/2
y = 45
So angle BRE is 45 degrees. Note how 45+45 = 90.
We also know that angle TAP and angle BRE are supplementary. They add up to 180 degrees
x+y = 180
x+45 = 180 ... replace y with 45
x+45-45 = 180-45 ... subtract 45 from both sides
x = 135
Since we defined x to be the measure of angle TAP, this means that angle TAP is 135 degrees

Gary said this model shows shaded. John said this model shows shaded.

C.

Answers
The question is missing critical information as it lacks the proportion or number related to the shaded part of the model. Without this detail or a visual representation, it's not possible to determine the accuracy of Gary or John's statements.
Explanation:The question provided seems to be missing critical information, specifically the proportion or number that Gary and John are referring to when they mention how much of a model is shaded. In a typical mathematics problem regarding fractions or percentages, students would be asked to determine if statements about the shaded portion of a model are correct. Without the visual model or additional context indicating the proportion of the model that is shaded, it's impossible to conclude which student, Gary or John, is correct.
In order to answer correctly, we would need either a clear description of the model and its shaded parts or, preferably, a visual representation. Then, we would analyze the shaded portion to assess which statement about the fraction or percentage shaded is accurate. If we had this information, we could illustrate the process of comparing the given fraction or percentage with the actual shaded section of the model.
Unfortunately, without the necessary details, we can neither confirm if Gary, John, or both are correct, nor can we properly address the question.

What are Congruent Triangles?
Transformations change the size or position of shapes. Congruent shapes are identical, but may be reflected, rotated or translated. Scale factors can increase or decrease the size of a shape. Congruent Triangles simply mean the triangles that possess the same size and shape
• The three sides are equal (SSS: side, side, side)
• Two angles are the same and a corresponding side is the same (ASA: angle, side, angle)
• Two sides are equal and the angle between the two sides is equal (SAS: side, angle, side)
• A right angle, the hypotenuse and a corresponding side are equal (RHS, right angle, hypotenuse, side)
Given data ,
∠1 and ∠2 are supplementary
So , ∠1 + ∠2 = 180°
∠1 ≅ ∠2
So , ∠1 and ∠2 are congruent
Since , we know that both of these angles are congruent and supplementary , both of the angles add up to 180°
So , each of the angle measures a total of ∠1 = 180° / 2
= 90°
And ∠2 = 90°
When the angle of a triangle is 90° , the angle is known as right angle
So ∠1 and ∠2 are right angles

Noam walks home from school by walking 8 blocks north and then 6 blocks east. How much shorter would his walk be if there were a direct path from the school to his house? Assuming that the blocks are square.
Answers
To find out how much shorter Noam's walk would be if there were a direct path from the school to his house, we need to calculate the displacement using the Pythagorean theorem. Noam walks 8 blocks north and then 6 blocks east. The displacement is the straight-line distance from the starting point to the endpoint. Therefore, the displacement is the square root of (8² + 6²), which is the square root of 64 + 36, which is the square root of 100, which is 10 blocks. So, if there was a direct path, Noam's walk would be 10 blocks shorter.
