Identify two equations from above that represent perpendicular lines and explain why you choose them

Answers

Answer:

parallel : (b) and (g)

perpendicular : (d) and (f)

Step-by-step explanation:

straight line equation : y = mx + c

Lines that are parallel have the the same gradient(m),

(b) and (g) are parallel, both of them has m= 1/2

Lines that are perpendicular will have the product of their

gradient(m) equal to -1. So, m1 × m2 = -1

(d) and (f) are perpendicular, because : -4 × ¼ = -1

The ratio of exterior angle and interior angle of a regular polygon is 12:6. The name of the regular polygon is

Answers

Answer:

Equilateral triangle

Step-by-step explanation:

sum the parts of the ratio, 12 + 6 = 18 parts

exterior angle + interior angle = 180°

180° ÷ 18 = 10° ← value of 1 part of the ratio , then

6 parts = 6 × 10° = 60° ← interior angle

12 parts = 12 × 10° = 120° ← exterior angle

The sum of the exterior angles of a polygon = 360°

Divide 360° by 120° to find number of sides

360° ÷ 120° = 3

and since the interior angles are 60° , then

polygon is an equilateral triangle

What is the solution to the system of equations y = -1/2 x + 1 and y = 2x + 6?

Answers

Answer:

Since by the 2nd equation, we know that y is the same as 6-x, we can substitute that for y in the first equation:

y = 2x + 3 -> 6 - x = 2x + 3 -> 6 = 3x + 3 -> 3 = 3x -< x = 1 and by either of the two equations, that derives y = 5

Step-by-step explanation:

Answer:

ok you can use subsitution for this one

since y=2x+6

subsitute 2x+6 for y

3x-(2x+6)=6

3x-2x-6=6

add like terms

x-6=6

add 6 to both sides

x=12

subsitute

y=2x+6

y=2(12)+6

y=24+6

y=30

x=12

y=30

(x,y)

You can begin by breaking down √(160) into its prime factors.

√(160) = √(2 * 2 * 2 * 2 *2 * 5)

This can be broken down further by

Step-by-step explanation:

The tire has a diameter of 33 inches. If the tire rotates one time, about how many inches will the tire travel?

Answers

Given:

Diameter of a tire = 33 inches.

To find:

The distance covered by the tire if it rotates one time.

Solution:

We have,

Diameter of a tire = 33 inches.

Radius is the half of diameter. So, the radius of the tire is

[tex]\dfrac{33}{2}=16.5[/tex]

Thus, r = 16.6 inches.

We have to find the distance covered by the tire if it rotates one time. It means, we need to find the circumference of the tire.

[tex]C=2\pi r[/tex]

[tex]C=2(3.14)(16.5)[/tex]

[tex]C=103.62[/tex]

Therefore, the distance covered by the tire if it rotates one time is 103.62 inches.

How many solutions does the equation 2(x+1) = 2x+1 have?

Answers

Answer:

No Solutions

Explanation:

2(x + 1) = 2x + 1

Simplify both sides of the equation

2(x + 1) = 2x + 1

(2)(x) + (2)(1) = 2x + 1 [Distribute]

2x + 2 = 2x + 1Subtract 2x from both sides

2x + 2 − 2x = 2x + 1 − 2x

2 = 1

Subtract 2 from both sides

2 − 2 = 1 − 2

0 = −1

plz plz plz hury plz hury asap 1: Qin Shi HuangShihuangdi (Qin Shi Huang) Shang Yang introduced a range of administrative techniques: new methods to record available resources. He standardized measures and coinage, kept records of granary storage and initiated an accounting that prevented tax evasion tax evasion being a threat to the state's growth. When the ruler of Qin died, Shang Yang was left without protection at court, and jealous persons at court had Shang Yang executed. But his work lived on. In 314 BCE twenty-four years after the death of Shang Yang the kingdom of Qin won a military victory over nomads to its north. In 311, Qin expanded southward onto fertile plane against more nomadic people and defeated a state called Shu, and a Qin general, Zhang Yi, founded a new city, Chengdu. Other states were also expanding: Yan against so-called barbarians east of the Liao River, and Chu was expanding southward across the Yangzi River. War and conquest reduced the number of states to eleven. One of the eleven, Wei, had been reduced as a power by its war against Qi (pronounced chi). Qi appeared to be the dominant power, and Qin joined a coalition of four other states against Qi, which the allies of Qin feared more than they did Qin. Qi was well organized and densely populated relative to most other states. It was high in food production and had grown wealthy also from trade in iron and other metals, and, in 256 BCE, Qi absorbed Lu. Qin expanded into Zhou family territory, an area around Luoyang containing about 30,000 people and thirty-six villages. A Zhou prince counter-attacked, trying to claim the Zhou throne for himself. Qin's army defeated him, and this brought the great Zhou dynasty, dating from 1045 BCE, to an end, 256 BCE. In 246 BCE, Yong Zheng, the thirteen-year-old son of the ruler of Qin, succeeded his father. After sixteen years of rule, Zheng embarked upon the conquest of the remaining states that had been a part of Zhou civilization. According to Victoria Tin-bor Hui, the historian Mark Edward Lewis describes Qin, in his words, as having enjoyed "a splendid geographic situation... It was accessible from the East only through the Hangu Pass and from the southeast through the Wu Pass." And, writes Victoria Tin-bor Hui, Ralph D. Sawyer "similarly thinks that Qin occupied a 'virtually unassailable mountainous bastion'. " note11 In the wars that led to a unification of what had been Zhou civilization, armies of hundreds of thousands were involved on both sides. Qin was driven by the fear that if it didn't defeat all of the others they would combine and crush it. Qin defeated one state after another: Han in the year 230, Zhao in 228, Wei in 225, the large but more sparsely populated and less tightly knit Chu in 223, Yan in 222 and Qi in 221. Occasionally, to eliminate possible military opposition, Qin's armies slaughtered all enemy males of military age. The Warring States Period was over. Zheng had become ruler of all that had been Zhou civilization. He went to a sacred mountain, Dai Shan, where, it would be said, he received the Mandate from Heaven to rule the "entire world." He took the name Shihuang-di (di signifying emperor). He was also named Qin Shi Huang. He then expanded his frontiers southward to Guangzhou and to Guangxi, creating what would thereafter be considered China. And he pushed into Annam, or northern Vietnam an area the Chinese would hold only temporarily. Shihuangdi had become the first emperor of China.Describe Zheng's position and the effects of his actions after the "period of Warring States".Describe Liu Bang's view of government during the Han Dynasty.
