Ⓒ {1, 2, 3, 6, 9, 13, 14}
Step-by-step explanation:
One way to find the union of two sets is to list all the elements of both sets in order, then delete any duplicates.
Here, joining the two sets gives ...
{1, 6, 2, 3, 14, 2, 9, 13, 1}
Putting these elements into numerical order, we have ...
{1, 1, 2, 2, 3, 6, 9, 13, 14}
I have highlighted the duplicates. Deleting those gives us the desired union of the two sets:
X ∪ Y = {1, 2, 3, 6, 9, 13, 14} . . . . . matches choice C

A French submarine is at a depth of -200 meters, and a Russian submarine is at
a depth of -205 meters, which submarine is deeper?
A. French submarine
B. Russian submarine
The Russian submarine is deeper since -205 meters is a greater depth than -200 meters when comparing negative values.
To compare the depths of the two submarines, we need to consider the numerical value of their depths. When we look at depths, the larger the negative number, the deeper the location. In this case, a depth of -200 meters means the French submarine is closer to the surface than a depth of -205 meters.
Therefore, the Russian submarine is deeper because -205 is lower than -200 when considering depths below sea level.
(2y-1)(4y-3)
A.-2y+3
B.8y^2-10y-3
C.8y^2-10y+3
D.8y^2-2y+3
Answer:Simplifying
(2y + -1)(4y + -3) = 0
Reorder the terms:
(-1 + 2y)(4y + -3) = 0
Reorder the terms:
(-1 + 2y)(-3 + 4y) = 0
Multiply (-1 + 2y) * (-3 + 4y)
(-1(-3 + 4y) + 2y * (-3 + 4y)) = 0
((-3 * -1 + 4y * -1) + 2y * (-3 + 4y)) = 0
((3 + -4y) + 2y * (-3 + 4y)) = 0
(3 + -4y + (-3 * 2y + 4y * 2y)) = 0
(3 + -4y + (-6y + 8y2)) = 0
Combine like terms: -4y + -6y = -10y
(3 + -10y + 8y2) = 0
Solving
3 + -10y + 8y2 = 0
Solving for variable 'y'.
Factor a trinomial.

Set the factor '(1 + -2y)' equal to zero and attempt to solve:
Simplifying
1 + -2y = 0
Solving
1 + -2y = 0
Move all terms containing y to the left, all other terms to the right.
Add '-1' to each side of the equation.
1 + -1 + -2y = 0 + -1
Combine like terms: 1 + -1 = 0
0 + -2y = 0 + -1
-2y = 0 + -1
Combine like terms: 0 + -1 = -1
-2y = -1
Divide each side by '-2'.
y = 0.5
Simplifying
y = 0.5
Subproblem 2
Set the factor '(3 + -4y)' equal to zero and attempt to solve:
Simplifying
3 + -4y = 0
Solving
3 + -4y = 0
Move all terms containing y to the left, all other terms to the right.
Add '-3' to each side of the equation.
3 + -3 + -4y = 0 + -3
Combine like terms: 3 + -3 = 0
0 + -4y = 0 + -3
-4y = 0 + -3
Combine like terms: 0 + -3 = -3
-4y = -3
Divide each side by '-4'.
y = 0.75
Simplifying
y = 0.75
Solution
y = {0.5, 0.75}

Find the slope given the points (-1,-9) and (5,-6)
The slope between the points (-1, -9) and (5, -6) is found using the slope formula which results in a slope of 0.5.
Explanation:The subject of your question falls under Mathematics, specifically within Algebra. To find the slope between two points, we will use the formula for the slope which is change in y divided by the change in x, or (y2 - y1) / (x2 - x1).
In your case, the given points are (-1,-9) and (5,-6) where (-1,-9) is (x1,y1), and (5,-6) is (x2,y2). Therefore, applying the slope formula, we get the slope as: (-6 - (-9)) / (5 - (-1)) which equals to 3/6. It simplifies down to 0.5.

The slope of the line passing through the points (-1,-9) and (5,-6) is calculated using the slope formula, resulting in a slope of 1/2.
To find the slope of a line that passes through two points,
(-1,-9) and (5,-6), we use the slope formula which is given by the difference
in the y-coordinates divided by the difference in the x-coordinates. The formula is:
Slope (m) = (y2 - y1) / (x2 - x1)
Substituting the given points into the formula:
Slope (m) = (-6 - (-9)) / (5 - (-1))
Slope (m) = (3) / (6)
When simplified, this gives:
Slope (m) = 1/2
So, the slope of the line that passes through the points (-1,-9) and (5,-6) is 1/2.

Find the perimeter of the parallelogram (khan academy) (15 points)
The perimeter of the parallelogram is 18 units.
We have,
From the graph,
There are two pairs of parallel sides.
Now,
One pair of parallel sides = 4 units each
Another pair of sides = x units each
And,
Applying Pythagorean theorem in ΔABC.
x² = 4² + 3²
x² = 16 + 9
x² = 25
x = 5
Now,
The perimeter of the parallelogram.

The value of the rational expression which is undefined is x = -9
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
In an equation, the expressions on either side of the equals sign are called the left-hand side (LHS) and the right-hand side (RHS), respectively. The equals sign (=) indicates that the two expressions have the same value, and that the equation is true for certain values of the variables involved.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. It typically consists mathematical operations, such as addition, subtraction, multiplication, division, and exponentiation.
Given data ,
Let the equation be represented as A
The rational expression is undefined when the denominator is equal to zero. So, we need to solve the equation:
x + 9 = 0
Subtracting 9 from both sides, we get
x = -9
Therefore, the value of x that makes the rational expression undefined when x = -9, because it would make the denominator equal to zero.
Hence , the expression is x = -9

A test is worth 50 points. Multiple-choice questions are worth 1 point, and
short-answer questions are worth 3 points. If the test has 20 questions, how
many multiple-choice questions are there?
Answer:
The answer is 2
Step-by-step explanation:
This is because 3 times 16 is 48, so add 2 more multiple choice questions and it equals 50. Hope this helps :p
Answer:
5 multiple choice questions
Step-by-step explanation:
Set 1 point questions to "x" and 3 point questions to "y".
You can form the equations:
x + y = 20
1x + 3y = 50
Using substitution, you can rewrite the first equation to: "x = 20 - y" and plug it into the bottom equation.
1(20-y) + 3y = 50, then open parenthesis and combine like terms
2y = 30, then divide both sides by 2
y = 15, there 20 total questions, and 15 short answer questions, so there are 5 multiple choice questions
3*15+1*5 = 45 + 5 = 50

If 15 out of every 75 new salons are still open for business after 3 years, what percent of salons are NOT still in business after 3 years?
Answer:
80%
Step-by-step explanation:
If 15 salons are open, this means that 60 are closed. 60 out of the 75 salons is 80% if you divide 60 by 75.
Final answer:
To find the percentage of new salons not still in business after 3 years, subtract the number still open from the total, divide by the total number of salons, and multiply by 100. This calculation shows that 80% of the new salons have closed.
Explanation:
The question asks us to find what percent of new salons are not still in business after 3 years given that 15 out of every 75 are still open. First, we find the number of salons that closed. Since 15 salons are still open, the number that closed is 75 - 15, which equals 60 salons. To find the percentage of salons that closed, we divide the number of closed salons by the total number of new salons, and then multiply by 100.
So, the calculation to find the percentage that closed is:
(60 closed salons / 75 total salons) × 100 = 80%
Therefore, 80% of the new salons are not still in business after 3 years.
