After analyzing each option and testing them in the equation UW = 9x - 9, none of the provided options (5 units, 6 units, 30 units, 36 units) result in a consistent solution for the length of UW in units. Without additional information or a correct option, it is impossible to determine the length of UW in units.
Explanation:The student's question asks us to find the length of segment UW in units given that the formula for its length is UW = 9x - 9. To ascertain the correct length, we need a value for 'x'. Since the options provided are measured in units and do not contain variables, we have to assume that 'x' represents a specific value that, when substituted into the equation, will yield one of the given numerical options for UW.
Going through the provided options, we can test each number to see which, when substituted into 'x', will make UW a whole number. Starting with the smallest '5 units' and '6 units', we quickly find that none of these values, when multiplied by 9 and then decreased by 9, will yield themselves as a result. Thus, they can be dismissed as possible lengths of UW.
Moving on to '30 units' and trying x = 30 in the equation UW = 9x - 9, we get UW = 9(30) - 9 = 270 - 9 = 261, which does not match. Lastly, checking x = 36 in the equation gives us UW = 9(36) - 9 = 324 - 9 = 315, which is also not an option. None of the provided options are valid when 'x' is placed into the equation UW = 9x - 9.
Therefore, without additional information or a correct choice in the options, we cannot determine the length of UW in units.
Which expression is a factor of 2xy + 6x – 3y – 9?
2x – 3
2y + 3
x – 2
y – 3
...?
Answer:
(2x-3) is the answer.
Step-by-step explanation:
The given expression is :
[tex]2xy+6x-3y-9[/tex]
Grouping these terms we get-
[tex]2x(y+3)-3(y+3)[/tex]
So, the factors are :
[tex](2x-3)(y+3)[/tex]
Hence, out of the given options (2x-3) is the answer.
And he other factor is (y+3) that is not mentioned in the options.
Final answer:
The factor of the expression 2xy + 6x - 3y - 9 is 2x - 3, which is found by factoring the expression by grouping.
Explanation:
The expression given is 2xy + 6x − 3y − 9. To determine which expression is a factor of it, we can attempt factoring by grouping. Grouping the terms as (2xy + 6x) and (− 3y − 9) and factoring out the common factors from each group gives us:
2x(y + 3)−3(y + 3)We can see that (y + 3) is a common factor between the two groups. Factoring this out, we get:
(2x − 3)(y + 3)
This shows that 2x − 3 is a factor of the given expression.

If CDFG is a kite, find the measure of Angle D.
a. 124
b. 120
c. 118
d. 122
Without additional details about the kite CDFG, such as angle measures or side lengths, it is impossible to provide an exact measure for Angle D.
Explanation:The question asks to find the measure of angle D in a kite named CDFG. Without additional information such as angle measures or side lengths, it is impossible to determine the exact measure of Angle D. However, we know in a kite, there are two pairs of adjacent sides that are equal, and one pair of opposite angles (the angles between the unequal sides) are equal. Typically, the diagonals of a kite are perpendicular, and one of the diagonals bisects the other. This information still does not provide enough context to solve for the measure of angle D without more specific details about the lengths of the sides or measures of other angles.

How much of the circle is shaded? Write your answer as a fraction in simplest form.
Answer:
[tex]13/28[/tex]
Step-by-step explanation:
Let
x-----> the shaded area
we know that
[tex]x+\frac{1}{4}+\frac{2}{7}=1[/tex]
Because the complete circle represent the [tex]100\%[/tex]
and
[tex]100\%=100/100=1[/tex]
solve for x
Multiply by [tex]28[/tex] both sides
[tex]28x+7+8=28[/tex]
[tex]28x=28-15[/tex]
[tex]28x=13[/tex]
Divide by [tex]28[/tex] both sides
[tex]x=13/28[/tex] ----> fraction irreducible

How do i find the area between the two curves
Final answer:
To find the area between two curves, calculate the definite integral of the difference between the two functions over the interval of interest.
Explanation:
To find the area between two curves, you need to calculate the definite integral of the difference between the two functions over the interval of interest. Let's say the two curves are f(x) and g(x), and you want to find the area between them from x = a to x = b. You can write the integral as follows:
Area = ∫(f(x) - g(x)) dx from a to b
Then you can evaluate this integral using integration techniques, such as u-substitution or integration by parts, to find the area between the two curves.

The sum of two positive integers, a and b, is at least 30. The difference of the two integers is at least 10. If b is the greater integer, which system of inequalities could represent the values of a and b?
A. a + b ≥ 30 b ≥ a + 10
B.a + b ≥ 30 b ≤ a – 10
c. a + b ≤ 30 b ≥ a + 10
D. a + b ≤ 30 b ≤ a – 10
Option A, with inequalities a + b ≥ 30 and b ≥ a + 10, correctly describes these conditions.
We are given that the sum of two positive integers, a and b, where b is greater, is at least 30, which can be represented as a + b ≥ 30.
The difference between the two integers is also at least 10, and since b is the greater integer, this relationship is given by b - a ≥ 10.
The correct system of inequalities that represents these conditions is Option A:
a + b ≥ 30
b ≥ a + 10
Option B is incorrect because it suggests b is less than or equal to a - 10, which doesn't make sense in this context since b is the greater integer.
Options C and D are incorrect because they suggest that the sum of a and b is less than or equal to 30, which contradicts the given that the sum is at least 30.
I'm studying for a test, and I can't seem to remember how to find missing coordinates. Here's one example of the question,
Fill in the other coordinate for the line 3x-5y=2 (2,) I need to find Y. I thought that my answer was 4/5 (4over5) I did, 3 times 2, (6) -6 on both sides, so then I had -5y = -4. So I divided both by 5. . . But that doesn't sound right to me! Anyone know what I'm doing wrong? Or right? Thanks!

Step-by-step explanation:
The function for the cost of materials to make a hat is f(x) = one half x + 1, where x is the number of hats. The function for the selling price of those hats is g(f(x)), where g(x) = x + 2. Find the selling price of 10 hats. A. 6 b. 8 c. 10 d. 12
The selling price for 10 hats, calculated by applying the cost function f(x) to find the cost and then the selling price function g(x), is $8.
Explanation:The selling price of 10 hats can be found by first calculating the cost of materials to make those hats using the function f(x) = 0.5x + 1, and then applying the g(f(x)) function to find the selling price, where g(x) = x + 2.
First, we calculate the cost for making 10 hats:
f(10) = 0.5 imes 10 + 1 = 5 + 1 = 6.
Now, we use the selling price function g to calculate the selling price for 10 hats:
g(f(10)) = g(6) = 6 + 2 = 8.
Therefore, the selling price for 10 hats is $8.

The list of a certain tool is x dollars. In store A the original selling price of the tool was $50 less than the list price, and the current selling price is 10% less than the original selling price. In store B the original selling price of the tool was 10% less than the list price, and the current selling price is $50 less than the original selling price.
A) Quality A is greater
B) Quality B is greater
C) The two quantities are equal
To compare the selling prices in store A and store B for the tool described:
Let's denote the list price of the tool as x dollars.
In Store A:
- Original selling price = List price - $50
- Current selling price = 90% of the original selling price
In Store B:
- Original selling price = 90% of the list price
- Current selling price = Original selling price - $50
Now, we can calculate the selling prices for both stores and compare:
For Store A:
Original selling price in Store A = x - 50
Current selling price in Store A = 0.9(x - 50)
For Store B:
Original selling price in Store B = 0.9x
Current selling price in Store B = 0.9x - 50
To determine which quantity is greater, we need to compare the expressions for the current selling prices in both stores. We will simplify the expressions to make the comparison easier.
Store A:
0.9(x - 50) = 0.9x - 45
Store B:
0.9x - 50
Comparing the simplified expressions, we see that:
0.9x - 45 is greater than 0.9x - 50
Therefore, Store A has a greater current selling price for the tool compared to Store B.
So, the correct answer is:
A) Quality A is greater.

Bonds issued by Raxin Accounting have a total yield of 11.4% annually, while Raxin Accounting stocks have a total yield of 14.4% annually. If you invest $2,600 in Raxin Accounting bonds and $2,000 in Raxin Accounting stocks, which investment will have a greater return after nine years, and how much greater will it be
Answer:
A. in edge
Step-by-step explanation:
$75.69
Final answer:
After nine years, investing $2,600 in Raxin Accounting bonds will yield a greater return than investing $2,000 in their stocks, specifically $579.30 more due to the effect of compound interest.
Explanation:
If you invest $2,600 in Raxin Accounting bonds with a total yield of 11.4% annually and $2,000 in Raxin Accounting stocks with a total yield of 14.4% annually, we can calculate the future value of both investments after nine years using the formula for compound interest: Future Value = Principal × (1 + rate)^time.
For bonds: Future Value = $2,600 × (1 + 0.114)^9 = $2,600 × 2.7845 = $7,239.70
For stocks: Future Value = $2,000 × (1 + 0.144)^9 = $2,000 × 3.3302 = $6,660.40
Comparing the future values, the investment in Raxin Accounting bonds will yield a greater return after nine years, specifically $579.30 more than the investment in stocks.
