Answer:
The slope of the line is 4.
The Y intercept of the line is -6.
Step-by-step explanation:
The slope intercept form of a line is
[tex]y=mx+b[/tex] .... (1)
where, m is slope and b is y-intercept.
The given equation of line is
[tex]y=4x-6[/tex] .... (2)
On comparing (1) and (2) we get
[tex]m=4[/tex]
[tex]b=-6[/tex]
It means the slope of the line is 4 , The Y intercept of the line is -6. the graph of a linear function is a straight line.
The value of y is -6 at x=0, so the line do not passes through the origin.
Therefore, the correct statements are "the slope of the line is 4 and the Y intercept of the line is -6".
The solutions are
The slope of the line is 4
The y-intercept of the line is –6
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y coordinate of second point
y₁ = y coordinate of point one
m = slope
x = x coordinate of second point
x₁ = x coordinate of point one
Given data ,
Let the equation be y = 4x - 6
Now , the equation is of the form y = mx + b where m is the slope and b is the y-intercept
Therefore , the slope of the equation is m = 4
And the y intercept is -6
Hence ,
The slope of the line and the y-intercept of the line is –6

- 4 + 8 -10 + (-2) Which expression shows the commutative property?
James surveyed people at school and asked whether they bring their lunch to school or buy their lunch at school more often. The results are shown below.
Bring lunch: 46 males, 254 females
Buy lunch: 176 males, 264 females
The events "male” and "buys lunch” are not independent because
P(buys lunch | male) = P(male) = 0.4.
P(male | buys lunch) = P(male) = 0.3.
P(buys lunch | male) = 0.3 and P(male) = 0.4.
P(male | buys lunch) = 0.4 and P(male) = 0.3.
Answer:
The correct option is 4.
Step-by-step explanation:
Given information:
Bring lunch : 46 males, 254 females
Buy lunch : 176 males, 264 females
Total number of peoples is
[tex]46+254+176+264=740[/tex]
Total number of males is
[tex]46+176=222[/tex]
The probability of male is
[tex]P(Male)=\frac{Males}{Total}=\frac{222}{740} =0.3[/tex]
Since probability of males is 0.3, therefore options A and C are incorrect.
Total number of persons who buys lunch is
[tex]176+264=440[/tex]
The probability of persons who buys lunch is
[tex]P(\text{Buys lunch})=\frac{\text{Buys lunch}}{Total}=\frac{440}{740} =\frac{22}{37}[/tex]
We need to find the probability of P(male | buys lunch).
According to the conditional probability, we get
[tex]P(\frac{A}{B})=\frac{P(A\cap B)}{P(B)}[/tex]
P(male | buys lunch)[tex]=\frac{P(\text{male }\cap \text{ buys lunch})}{P(\text{buys lunch})}[/tex]
P(male | buys lunch)[tex]=\frac{\frac{176}{740}}{\frac{22}{37}}[/tex]
P(male | buys lunch)[tex]=\frac{2}{5}=0.4[/tex]
Therefore the correct option is 4.

Which expression is equivalent to 2x - 17? A) -17 + 2x B) -2x + 17 C) -2x - 17 D) 17 + 2x
The expression (2x - 17) is equivalent to (-17 + 2x). So, option A is the correct answer.
To determine which expression is equivalent to (2x - 17), we can use the distributive property to simplify each option.
A) (-17 + 2x):
This expression is equivalent because of the commutative property of addition. So, (A) is correct.
Here's the detailed calculation:
Given expression: [tex]\(2x - 17\)[/tex]
We'll use the distributive property:
[tex]\(2x - 17 = (2x) + (-17)\)[/tex]
Thus, the expression is already in the form of option A, which is [tex]\(-17 + 2x\)[/tex]. So, option A is the correct answer.
In summary, the expression (2x - 17) is equivalent to option A, (-17 + 2x).
Describe how you regroup when you find the sum of 64+43
The required regroup of the sum of 64+43 into 60+4 and 43 into 40+3.
What is the number system?A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches.
The sum of two numbers is given in the question as:
64 + 43
As per the given condition, the required solution would be as:
To regroup, just separate the larger numbers into smaller amounts that can be put together more easily. We frequently reorganize numbers into those that terminate in 0 because they are easier to add. For example, 64 may be divided into 60+4 and 43 into 40+3. This makes adding easy since you can first add 60 and 40, which equals 100. The smaller numerals 100+4+3=107 can then be added.
Thus, the required regroup of the sum of 64+43 into 60+4 and 43 into 40+3.

Modeling with systems of linear inequalities
Modeling with systems of linear inequalities involves using multiple linear inequalities to represent constraints and solve problems with multiple variables. We can graph the inequalities on a coordinate plane and find the feasible region, which represents all the solutions that satisfy the constraints.
Explanation:Modeling with systems of linear inequalitiesModeling with systems of linear inequalities is a mathematical concept that involves using multiple linear inequalities to represent constraints in a real-world situation. This allows us to model and solve problems involving multiple variables and constraints, such as optimizing profit or finding feasible solutions.
Here's an example:
Let's say we have two variables, x and y, representing the number of units of two products.We also have two inequalities, 2x + 3y <= 10 and x + y >= 4.These inequalities represent constraints on the production and sales of the products.To model this situation, we graph the two inequalities on a coordinate plane.The feasible region, the area where the shaded regions of both inequalities overlap, represents the set of solutions that satisfy all the constraints.We can then use this model to analyze and solve various problems, such as finding the maximum profit by maximizing a certain objective function within the feasible region.Learn more about Modeling with systems of linear inequalities here:https://brainly.com/question/34246005

plot -2 1/2 and 1 3/4 on a number line
To plot -2 1/2 and 1 3/4 on a number line, draw a line with zero at middle. Move 2.5 units to the left from zero for -2 1/2 and place a dot. Then, move 1.75 units to the right from zero for 1 3/4 and place a dot.
Explanation:To plot the numbers -2 1/2 and 1 3/4 on a number line, you first need to understand that these are mixed numbers. -2 1/2 means "two and a half units to the left of zero", whereas 1 3/4 means "one and three quarters units to the right of zero".
Step 1: Draw a number line with zero in the middle. Include distance markers each representing 1 unit. For the purpose of this exercise, let's say negative numbers are on the left and positive numbers are on the right.
Step 2: To plot -2 1/2, start at 0 and move 2.5 units to the left (-2 for the whole number and -0.5 for the fractional part). Place a point here.
Step 3: To plot 1 3/4, start at 0 and move 1.75 units to the right (+1 for the whole number and +0.75 for the fractional part). Place a point here.
This is how you plot the numbers -2 1/2 and 1 3/4 on a number line.

A metal rod is 2/3 meters long. It will be cut into pieces that are each 1/12 meters long. How many pieces will be made from the rod?
The 2/3 meter long metal rod can be divided into 8 pieces each of length 1/12 meters by dividing the total length of rod with the length of each piece.
Explanation:The subject of this question is mathematics, and it involves division. When we are given a total length and the length of each piece, we can find the number of pieces by dividing the total length by the length of each piece.
Here, the total length of the metal rod is 2/3 meters. Each piece that we want to cut is 1/12 meters long.
To find the number of pieces, we simply perform the division: (2/3)÷(1/12). When we divide fractions, we multiply the first fraction by the reciprocal of the second fraction. So this becomes (2/3)*(12/1) = 24/3 = 8 pieces.
So the metal rod can be cut into 8 pieces each 1/12 meter long.

Answer:
The percentage of people surveyed that were satisfied with the car is 55%.
Step-by-step explanation:
The statement indicates that in a survey 1,100 people of 2,000 surveyed said that they would buy the car they have again and from this, you can inferred that they are satisfied with the car. So, to calculate the percentage of people surveyed that were satisfied with the car you have to divide 1,100 by 2,000 that is the total number of people surveyed and then, multiply the result by 100:
1,100/2,000=0.55*100= 55%

The sum of 4 consecutive integers is 130
To find the sum of 4 consecutive integers, set up an equation and solve for the unknown numbers. The solution is the four consecutive integers 31, 32, 33, and 34.
Explanation:To find the sum of 4 consecutive integers, we can set up an equation and solve for the unknown numbers. Let's assume the first number is n.
So, the sum can be represented as n + (n+1) + (n+2) + (n+3) = 130.
Combining like terms, we get 4n + 6 = 130. Solving this equation, we find that n = 31. Therefore, the four consecutive integers are 31, 32, 33, and 34.
