Answer:
To prove that N is a proper subset of M, show that every element of N is an element of M but there exists some elements of M which are not in N.
M= {4, 8, 12, 16, 20, 24...}
N= {12, 24, 36, 48, 60...}
Similar to example 6, 12 is a multiple of 4.
If x∈N,
then x= 12m for some positive integer m.
∴ x= 4(3m)
Hence, x is a multiple of 4.
i.e. x∈N.
Thus, every element of N is an element of M, but there exists some elements of M which are not elements of N. For example, 4, 8 and 16 are elements of M but are not elements of N. Thus, N is a proper subset of M. (shown)
Explanation:
∈ is the symbol of 'element of'. Thus, x∈N means that x is an element of N.
☆ Think of subsets like subtopics:
If differentiation is a subtopic of calculus, differentiation is a part of calculus but calculus is not only about differentiation since it includes integration too. Thus, there are numbers, which we call elements, in M that are not in N but all elements in N are in M.

i don't understand the question ive tried to answer it but i got it wrong
Answers
Answer: m^3
Step-by-step explanation:
Taking the square root of something is the same as raising it to the half power the square root of 4 is equal to 4^(1/2). This hold true with any root, not just square root. M^(3b) to the b root is equal to m^(3b x (1/b)). Ignore the base (m) for a second and the exponents make 3b x (1/b) which equals (3b/b). The b on the top and bottom cancel and you’re left with a 3. The answer is m^3

Step-by-step explanation:
Choose all of the equations that are equivalent to 8k = 20.
A. 8k - 4 = 20 + 4
B. 8k + 4 = 20 - 4
C. 8k x 3 = 20 x 3
D. 8k + 10 = 20 + 10
E. 8k x 5 = 20 + 5
Answers
The solution is Option C , Option D
The value of the equation is 8k = 20
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
8k = 20 be equation (1)
8k x 3 = 20 x 3
Divide both sides of the equation by 3 , we get
8 k = 20
Therefore , the value of k = 20/8
8k + 10 = 20 + 10
On simplifying the equation , we get
Subtracting 10 on both sides of the equation , we get
8k = 20
Therefore , the value of k = 20/8
Hence , the equation is 8k = 20

[tex]\frac{1}{4}[/tex]
Step-by-step explanation:
In this question, we have to find the slope with the given coordinates.
To find our slope, we would use the slope formula: [tex]m = \frac{y2-y1}{x2-x1}[/tex]
Plug in your coordinates and solve:
[tex]m = \frac{18-12}{40-16}\\\\m=\frac{6}{24}[/tex]
Simplify the fraction:
[tex]m=\frac{1}{4}[/tex]
The slope would be [tex]\frac{1}{4}[/tex]

Is (2, 10) a solution to this system of equations?
y = 4x + 2
y = x + 8
Answers
Answer:
Yes, (2, 10) is a solution to this system:
y = 4x + 2
y = x + 8
Step-by-step explanation:
When graphed, the two equations cross at (2,10) making it a solution.
Answer:
Yes
Step-by-step explanation:
If y=4x+2 and y=x+8, then 4x+2=x+8
4x+2=x+8
4x=x+6
3x=6
x=2
Plugging this into the original equation "y=x+8", we obtain the result that y=10.
This means, (2, 10) is a solution to the system.

For the linear model, y = -67.9x +679, the distance, in miles y, is a function of time, x, in hours. Use the model to calculate the total distance, in miles, at x = 2 hours.
1. cannot be determined
2. 10 miles
3. 814.8 miles
4. 543.2 miles
Pls help me
Answers
Answer:
The total distance in miles at x = 2 hours will be 543.2 miles.
Step-by-step explanation:
Given
Given the linear model function
y = -67.9x +679
where
y represents the distance, in miles y, is a function of time, x, in hours
To determine:
Use the model to calculate the total distance, in miles, at x = 2 hours
substituting x = 2 in the function
y = -67.9x +679
y = -67.9(2) +679
y = -135.8 + 679
y = 543.2 miles
Therefore, the total distance in miles at x = 2 hours will be 543.2 miles.

In 2021 Florida's minimum wage will be $10 per hour. In 2026 the minimum wage will increase to $15 per hour. What is the percent change
of Florida's minimum wage from 2021 to 2026? *Round to the nearest whole percent*
Answers
Answer:
50% value change.
Step-by-step explanation:
A 100% increase from 10 would be 20. It's the equivalent of doing 10 times 2. We need 15 though which is half the distance in value to 10 than 20 is. Half of 100% is 50%.
Therefore, $15 is a 50% percent change from $10.

What is the y intercept of the line whose equation is 3y=6x +12
Answers
Answer:
The y-intercept b = 4.
Please also check the attached graph.
Step-by-step explanation:
We know that the slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the slopeb is the y-interceptGiven the equation
3y = 6x + 12
Let us convert the equation into the slope-intercept form by dividing the equation by 3
y = 2x + 4
Thus, the equation into the slope-intercept form is:
y = 2x + 4
now comparing with the slope-intercept form of the line equation
Therefore, the y-intercept b = 4
Determining the y-intercept through Graph:
Please also check the attached graph of the equation 3y=6x +12.
We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.
From the graph, it is clear that:
at x = 0, the value of y = 4
Thus, the point (0, 4) represents the y-intercept of the equation 3y=6x +12 where y = 4 is the y-intercept.
