Step-by-step explanation:
y - 2 = 3(x - 1)
y - 2 = 3x - 3
y = 3x - 1
A number is five less than one fourth of itself
Answer:
x = 1/4x - 5
Step-by-step explanation:
Step 1: Translate from word to math
A number = x
five less = -5
one-fourth = 1/4
of itself = x
Step 2: Combine
x = 1/4x - 5

Answer:
m∠E = 43°Step-by-step explanation:
AB║CD ⇒ m∠AGH = m∠CHF = 119° {corresponding angles}
m∠BGE = m∠AGH = 119° {vertical angles}
m∠BGE + m∠B + m∠E = 180° {sum of angles in triangle}
119° + 18° + m∠E = 180°
m∠E = 180° - 137° = 43°

The distance on a map between a student’s house and her job is 6 cm. On the same map, the distance between her house and her school 8 cm. The actual distance from her house to school is 12 km. If d represents the approximate distance in km between her house and her job, what is d?
Answer:
9km
Step-by-step explanation:
If the distance on the map of 8cm between her house and school is equal to 12km actual distance. This means that each cm on the map represent 1.5km in actual distance (12/8=1.5).
This means that D is equal to 9km actual distance, because if each cm represents 1.5km, then 6 cm represents 9km (6x1.5=9).
Hope this helped!
Answer:
B
Step-by-step explanation:
9 km
What is the length of NO?
N= (7,-4)
O=(-7,-4)
Answer:
I believe it would be 14.
Step-by-step explanation:
The distance between 7 and -7 should be 14.
The length of NO is 14 units
What is the length of NO?Distance between two points is the length of the line segment that connects the two points in a plane.
The formula to find the length is given by:
d =√((x2 – x1)² + (y2 – y1)²)
We:
N= (7,-4) : x1 = 7 , y1 = -4
O = (-7,-4): x2 = -7 , y2 = -4
Using the formula with the given values:
d=√((-7 – 7)² + (-4 – (-4))²)
d=√((-14 )² + (0)²)
d=√196
d= 14
Therefore, the length of NO is 14 units

Changes to the cities and the environment:
1) List some ways in which the Tokugawa Shogunate strengthened Japan's economy.
2) How did rice production change?
3) Why were more roads required around Edo as the city grew?
4) Why was timber such an important resource in medieval Japan?
5) Describe the environmental policies introduced to protect forests and change the way timber was harvested.
6) Write a paragraph to explain, in broad terms, the impact that the Tokugawa shogunate had on Japan.
Answer:
Sorry i don't really know all of the question but I hope the ones I know help.
Step-by-step explanation:
The second questions answers is:
The most significant change in rice production technologies started from 2000 to 2013 and it was the introduction and adoption of new rice seed varieties. Southern rice producers increased it by planting Hybrid and non-genetically modified herbicide.
The third questions answer;
more roads were required cause Edo grew into a huge city with a lot of buildings and they needed road.
The fourth question answer; timber was important cause it was used to supply construction needed for the growing of population in the peaceful time. some places like the Shogun Leyasu and many of the Daimyo started building huge castles and templates to show their power to each other.
Your school's drama club charges $10 per person for admission to a play. The club borrowed $400 to pay for costumes and props. After paying back the loan, the club has a profit of $100. Write an equation. Let x represent the number of people who attended the play.
Answer:
10x + 400 - y = 100
Step-by-step explanation:
Answer:
50 people came to the play
Step-by-step explanation:
Let x be the amount of people that attended the play
10x=400+100
10x=500
divide by 10 on both sides
50 people came to the play
400+100=500
40 people is $400 for the props
10 people makes $100

A triangle has side lengths of (6.4c-2.5)(6.4c−2.5) centimeters, (8.7c-7.8)(8.7c−7.8) centimeters, and (6.4d-1.2)(6.4d−1.2) centimeters. Which expression represents the perimeter, in centimeters, of the triangle?
Answer:
15.1c + 6.4d - 11.5
Step-by-step explanation:
Given the following :
Lengths of the side of a triangle :
(6.4c-2.5) centimeters
(8.7c-7.8) centimeters
(6.4d-1.2) centimeters
Assume the sides Given are labeled A, B and C respectively,
The perimeter of a triangle is related vyvtge formula :
Perimeter = (A + B + C)
Perimeter = (6.4c - 2.5) + (8.7c - 7.8) + (6.4d - 1.2)
= (6.4c - 2.5) + (8.7c - 7.8) + (6.4d - 1.2)
= 6.4c - 2.5 + 8.7c - 7.8 + 6.4d - 1.2
= 6.4c + 8.7c + 6.4d - 2.5 - 7.8 - 1.2
= 15.1c + 6.4d - 11.5

Heather is putting together a square bulletin board for her new room, and the area of the bulletin board is 196 cm2. What is the total distance around the bulletin board?
Answer:
the total distance is 56 cm
Step-by-step explanation:
Given that the area of the bulletin board is 196 cm^2
Based on this, the total distance around the bulletin board is
But before that we need to find out the side
As the area of square is
= side^2
196 = side^2
So side = 14
Now there are four sides, so the total distance is
= 4 × 14
= 56 cm
Hence, the total distance is 56 cm
Answer:
56 cm
Step-by-step explanation:
Simplify the expression: y9 * y-2
Answer:
[tex]y^7[/tex]
Step-by-step explanation:
If we want to simplify the expression [tex]y^9 \cdot y^{-2}[/tex], we have to note that exponent rules state that [tex]x^a \cdot x^b = x^{a+b}[/tex].
This means that if we add the exponents, that will be what we raise y to the power of.
[tex]9 + -2 = 9-2 = 7[/tex]
So [tex]y^7[/tex].

Connor bought a baseball card eight years ago that has depreciated by $120 since he purchased it. Find the average yearly change in value of the card.
Answer:
The average yearly change in the value of the card is $15/year
Step-by-step explanation:
Here in this question, we are interested in calculating the average yearly change in the value of the card.
From the question, we can see that the value of the baseball card has depreciated by $120, thus we simply want to calculate the average yearly charge in the card value.
Mathematically, that would be ;
the total depreciation value/ number of years
From the question, the total depreciation value is $120 while the number of years is 8
Thus; the average yearly change in value of the card = 120/8 = $15/year

Determine the measure of the angle labeled (4x+7)°.
Answer:
39°
Step-by-step explanation:
It is the same measure as the one labeled 6x-9, since these are vertical angles.
4x +7 = 6x -9
16 = 2x . . . . . . . . add 9-4x
8 = x
4x+7 = 4(8) +7 = 39
The angle is 39°.
