Answers
Answer:
69 degrees
Step-by-step explanation:
1) Find x
The angles measured x degrees and (x-28) degrees have a sum of 180 degrees because straight lines always have a measure of 180 degrees. Knowing this, construct the equation:
[tex]x+x-28=180\\2x-28=180[/tex]
Add 28 to both sides
[tex]2x-28+28=180+28\\2x=208[/tex]
Divide both sides by 2
[tex]\frac{2x}{2}= \frac{208}{2} \\x= 104[/tex]
Therefore, x is equal to 104 degrees.
2) Find the measure of the (x-28) degree angle
Plug x into x-28
[tex]x-28\\= 104-28\\= 76[/tex]
Therefore, the measure of this angle is 76 degrees.
3) Find y
All the interior angles in any triangle will add up to 180 degrees. Knowing this, we can construct another equation:
[tex](2y-1)+76+y= 180[/tex]
Open up the parentheses
[tex]2y-1+76+y= 180\\3y+75= 180[/tex]
Subtract both sides by 75
[tex]3y+75-75=180-75\\3y=105[/tex]
Divide both sides by 3
[tex]\frac{3y}{3}= \frac{105}{3} \\y=35[/tex]
Therefore, y is equal to 35 degrees.
4) Find the measure of the (2y-1) degree angle
Plug y into 2y-1
[tex]2y-1\\= 2(35)=1\\= 70-1\\= 69[/tex]
Therefore, y is equal to 69 degrees.
I hope this helps!

Answers
Answer:
$100 profit, $300 cost
Step-by-step explanation:
So 25% of $400 is $100, now we know she made $100 on the article
and the other $300 was the amount used to make the article i'm asuming
A woman sold an article for 400.00
made a profit of 25%
Cost price and profit is $100 profit, $300 cost.
What are the 4 types of profit?There are four levels of profit or profit margins: gross profit, operating profit, pre-tax profit, and net profit.
These are reflected on a company's income statement in the following sequence: A company takes in sales revenue, then pays direct costs of the product of service.
What is profit and example?Profit is a term that often describes the financial gain a business receives when revenue surpasses costs and expenses. For example, a child at a lemonade stand spends one quarter to create one cup of lemonade. She then sells the drink for $2. Her profit on the cup of lemonade amounts to $1.75.

Use what you've learned to write the equation of a parabola that is narrower than y = x ,
2
opens downward, and has vertex (2, – 4).
Answers
Answer:
y = -a(x – 2)² – 4
a > 1
Example:
y = -2(x – 2)² – 4
Step-by-step explanation:
y = a(x – h)² + k
____________________
vetex: (h, k)
a: vertical reflection or stretch/compression
__________________________________
If it opens downward, has a vertex of (2, -4) and is narrower than y = x².
Then x² will have a negative coefficient of less than -1 and the input of x will be subtracted by the x value of the vertex which is 2, and the output will be added by the y value of the vertex which is -4.
Therefore y = -a(x – 2)² – 4 where a > 1
Use the Desmos graph and equation to get the answer to the vertex, axis of symmetry (x=), x intercepts, and the y intercept

f(x)=x -10x+21
Answers
Answer:
Vertex: (5,-4)
Axis of symmetry: x=5
X-intercepts: (3,0) and (7,0)
Y-intercept: (0,21)
Step-by-step explanation:
The vertex would be the tip of the parabola, so the vertex is (5,-4)
The axis of symmetry would be a line cutting a parabola in half indicated by the line x=5
X-intercepts are where a function passes through the x-axis or when y=0, so in this case, the x-intercepts are (3,0) and (7,0)
The y-intercept of a function is where a function passes through the y-axis or when x=0, so our y-intercept is f(0)=0²-10(0)+21=21, or (0,21)

Six / 6
Step-by-step explanation:
Fifteen less than 4 times a number is 9, meaning we have to find the number.
Let the required number be x
4 times the number = 4x
15 less than 4 times the number = 4x-15
⇒ 4x – 15 = 9
⇒ 4x = 9 + 15
⇒ 4x = 24
⇒ x = 6
meaning the number is 6.

**WILL GIVE BRANLIEST**
Answers
Applying the inscribed angle theorem, the missing angles are:
m∠RUS = 65°m∠UST = 15°What is the Inscribed Angles Theorem?Based on the inscribed angle theorem, we have the following relationships:
Inscribed angle = 1/2(measure of intercepted arc)Central angle = measure of intercepted arc.Given the following:
m(RU) = 50°m(UT) = 30°Find m(RS):
m(RS) = 180 - m(RU)
Substitute
m(RS) = 180 - 50
m(RS) = 130°
Find m∠RUS:
m∠RUS = 1/2(m(RS) [inscribed angle theorem]
Substitute
m∠RUS = 1/2(130)
m∠RUS = 65°
Find m∠UST:
m∠UST = 1/2(m(UT))
Substitute
m∠UST = 1/2(30)
m∠UST = 15°
