Answer:
y = 4x - 4
Step-by-step explanation:
first, find the slope:
y2 - y1/ x2 -x1
8 - 0/ 3 - 1 = 4
no plug in your slope and one of the points to find the b:
y = mx+b
0 = 4 (1) + b
b= -4
so
y = 4x - 4

Chemical Change C. Neither physical nor chemical change D. Both physical and chemical change
Answer:
B) Chemical Change
Step-by-step explanation:

Chemical change changes the physical composition of the product(s) involved. These are usually not irreversible. Eg : Baking of a cake, getting bubbles during bake process meanwhile
What is the standard form of the polynomial,
9x2 + 5x + 27 + 2x3
The standard form of the given polynomial ( 9x² + 5x + 27 + 2x³ ) is 2x³ + 9x² + 5x + 27.
What is the standard form of the polynomial?
To write a polynomial in its standard form, we first simplify then write the terms in an descending order.
Given the polynomial; 9x² + 5x + 27 + 2x³
First, we move the constant 27 to the right end of the expression
9x² + 5x + 2x³ + 27
Next, we move 2x³ left end of the expression
2x³ + 9x² + 5x + 27
Therefore, the standard form of the given polynomial ( 9x² + 5x + 27 + 2x³ ) is 2x³ + 9x² + 5x + 27.

Step-by-step explanation:
Mr. Leto plans to save money to buy a carpet. If he saves $50 each week for 30 weeks, he will have saved the exact amount of money needed to buy the carpet. If Mr. Leto instead saves $75 each week, how many weeks will it take him to save the same amount of money?
Answer:
Number of new weeks = 20 week
Step-by-step explanation:
Total money saves = $50 x 30
Total money saves = $1,500
Find:
Number of new week
Computation:
Total money saves = Number of money save per week x Number of new weeks
1,500 = 75 x Number of new weeks
Number of new weeks = 20 week
in a geometrical progression,the product of the 2nd and 4th term is double the the 5th terms. and the sum of the first four terms is 80 find the G.p
The 15th term of the geometric progression is 9,565,94.
What is the 15th term of the geometric progression?A geometric progression can be expressed as an = a1rn-1 for some a1 and r. You are told that a2 * a4 = 2a5 and a1 + a2 + a3 + a4 = 80.
From the first equation, a2 = a1 r, a4 = a1 r3, and a5 = a1 r4. This tells us that
a1 r a1 r3 = 2 a1 r4
The r's and one a1 cancel leaving a1 = 2.
Now, plugging similarly into a1 + a2 + a3 + a4 = 80,
2 + 2r + 2r2 + 2r3 = 80
r3 + r2 + r + 1 = 40
In general, the easiest way to solve a cubic is by graphing, but here you know the answer will be a small integer, so just try a few. If we try r=3, we get 27 + 9 + 3 + 1 = 40 so r = 3.
So the geometric sequence here is an = 2 3n-1. The 15th term is then:
a15 = 2*3^14
a15 = 9,565,938.

Find the value of each variable.
Answer:
19. x = 65
20. x = 12
21. x = 35, y = 85
Step-by-step explanation:
19. 2x -10 = 120
2x (-10 + 10) = (120 +10)
2x/2 = 130/2
x = 65
20. 2x + 4x + 108 = 180
6x + (108 - 108) = (180 - 108)
6x/6 = 72/6
x = 12
21. 2x + 25 = 3x - 10
2x + (25 - 25) = 3x (- 10 - 25)
(2x - 3x) = (3x - 3x) - 35
-x/-1 = -35/-1
x = 35
3x - 10 + y = 180
3(35) - 10 + y = 180
105 - 10 + y = 180
(95 - 95) + y = (180 - 95)
y = 85

6 lumberjacks can cut down 15 mahogany trees in 2 hours. How much longer will
it take 8 lumberjacks to cut down 35 mahogany trees working at the same rate?
B. 1}hr
c.hr
A. 3hr
D. 21hr
9514 1404 393
Answer:
3.5 hr
Step-by-step explanation:
We assume that "the same rate" means effort per tree is a constant. "Effort" is measured as the product of lumberjacks and hours. Then ...
(lumberjacks)(hours)/trees = (6)(2)/15 = (8)(t)/35
Multiplying by 35/8, we have ...
(35/8)(12/15) = t = (3·4·5·7)/(2·3·4·5) = 7/2 = 3.5
It will take 8 lumberjacks 3.5 hours to cut down 35 trees.

Answer:
B.
Step-by-step explanation:
When you move right or left it's inside the parentheses and the opposite so right is - and left is + when you move up or down its the same so up is + and down is -.
Answer:
B
Step-by-step explanation:
It's asking for moving right 3 and down 2. To move right three, you have to subtract 3 (It's switched up). This goes inside the parenthesis, because if it was outside of the parenthesis, it would be going up or down. Now, to go down 2, you have to subtract 2 outside of the parenthesis (It's normal). That leaves you with f(x-3)-2. Therefore, the answer is B.

What is meant by mathematical equation?Equations come in two varieties: identities and conditional equations. All possible values of the variables result in an identity. Only certain combinations of the variables' values make a conditional equation true. Two expressions joined by the equals symbol ("=") form an equation.
Identify the question that is being asked. Write the pertinent details in straightforward statements. Give values that need to be discovered symbols. Find the mathematical connections between the assertions.
The most well-known equation in the entire universe is E=mc2. Just like that. It is succinct, elegant, and expresses a phenomenon that is so important that everyone should be aware of it.
Given,
The equation will be:
7x + 9y = 43
7(2) + 9(3) =41
14+ 27 = 41
Since the value that's is gotten not equal to 43

2/15 of an airline's flights are international. The airline's flights are equally divided among 8 countries. What fraction of the airline's flights are to each country? If the airline has 2700 flights in all, how many are international? How many are not international? How many are to each of the 6 countries?
Answer:
The fraction of the airline's flights for each country is 1 /60
The number of international airline flights is 360 flights
The number of flights for each of the 8 countries is 45 flights
Step-by-step explanation:
Given;
international airline's flights = 2/15
number of countries = 8
total number of the airline flight
The fraction of the airline's flights for each country;
[tex]= \frac{2}{15}*\frac{1}{8} \\\\ = \frac{1}{60}[/tex]
The number of international airline flights;
[tex]= \frac{2}{15} *2700\\\\= 360 \ flights \ are \ international[/tex]
The number of flights for each of the 8 countries;
[tex]= \frac{1}{8} *360\\\\= 45 \ flights \ \\\\OR\\\\= \frac{1}{60}*2700\\\\ = 45 \ flights[/tex]

Kathy ran the 400-meter dash in 60.48 seconds. She ran the 200 meter dash in 28.9 seconds.If she divided her 400-meter dash time in 8 equal time segments, how long would it take cathy to run one of these segments Please HELPPP MEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE
Answer:
Kathy would take 7.56 seconds to run each of the 8-time segments of the 400-meter dash.
Step-by-step explanation:
Kathy ran the 400-meter dash in 60.48 seconds, so if she now divided that time into 8 equal time segments we have:
[tex] t = 60.48 s [/tex]
By dividing the above equation into 8:
[tex] t = \frac{60.48 s}{8} = 7.56 s [/tex]
Hence, she would take 7.56 seconds to run each of the 8-time segments of the 400-meter dash.
