Y = -3x + 7
Y = 8x - 6
30x-5y = 25
20x + 10y = 90
-3x + 3y = 18
Answers
Answers:
Positive slopes:
Y = 8x - 6 with a slope of 8.
30x - 5y = 25 with a slope of 6.
Negative slopes:
-3x + 3y = 18 with a slope of -1.
Y = -3x + 7 with a slope of -3.
20x + 10y = 90 with a slope of -2.
Step-by-step explanation: Have a great day! :)
Answer:
Positive Slopes
2) y = 8x - 6
3) y = 6x - 5
5) y = 1x + 6
Negative Slopes
1) y = -3x + 7
4) y = -2x + 9
(Bold numbers indicate the slopes)
Step-by-step explanation:
y = mx + b is the slope intercept form of writing the equation of a straight line. In the equation 'y = mx + b', 'b' is the point, where the line intersects the 'y axis' and 'm' denotes the slope of the line. The slope or gradient of a line describes how steep a line is.
y = mx + b
m ~ slope of the line
b ~ intercept of the line
[tex]3) \: \: 30x - 5y = 25 \\ 30x - 25 = 5y \\ \frac{30x - 25}{5} = \frac{5y}{5} \\ 6x - 5 = y \\ \\ y = 6x - 5[/tex]
[tex]4) \: \: 20x + 10y = 90 \\ 10y = - 20x + 90 \\ \frac{10y}{10} = \frac{ - 20x + 90}{10} \\ y = - 2x + 9 \\ [/tex]
[tex] 5) \: \: - 3x + 3y = 18 \\ 3y = 18 + 3x \\ \frac{3y}{3} = \frac{18 + 3x}{3} \\ y = 6 + x \\ \\ y = x + 6[/tex]

Answer:
Reflection in the x-axis
Step-by-step explanation:
If the point (x, y) of the shape is rotated 180° about the origin, it will be transformed into the point (-x, -y).
If the point (-x, -y) is reflected in the Y-axis, it will be transformed into the point (x, -y). This transformation is equivalent to the reflection of (x, y) in the x-axis.

Write an essay on Drug Addiction.
Answers
Answer:
Drug abuse and addiction are a major burden to society. Drug addiction is a pathological or abnormal condition which arises due to frequent drug use. The disorder of addiction involves the progression of acute drug use to the development of drug-seeking behavior, the vulnerability to relapse, and the decreased, slowed ability to respond to naturally rewarding stimuli. Causes Drugs known to cause addiction include illegal drugs as well as prescription or over-the-counter drugs, according to the definition of the American Society of Addiction Medicine.
One very common belief is that drug abusers should be able to just stop taking drugs if they are only willing to change their behavior. What people often underestimate is the complexity of drug addiction — that it is a disease that impacts the brain and because of that, stopping drug abuse is not simply a matter of willpower. Through scientific advances we now know much more about how exactly drugs work in the brain, and we also know that drug addiction can be successfully treated to help people stop abusing drugs and resume productive lives. People think of drug abuse and will only think of illegal drugs like marijuana or cocaine. The truth is that there are a large number of people who are abusing drugs that are legal and prescribed only by doctors. There is a study done by the United Nations that says that the number of people who are addicted to legal prescription drugs is close to the number of people who are addicted to illegal drugs. In this study the drug abuse and addiction it isn’t about consumption but more on consequences. If your drug addiction starts to affect your everyday life you most likely you’re a drug abuser or you have an addiction problem. Drug abuse and addiction can have many effects on the brain. These repeated usages of drugs can cause the way your brain’s appearance and function.
So what is drug abuse and why do we become addicted to certain drugs? Substance abuse, also known as drug abuse, is a patterned use of a substance (drug) in which the user consumes the substance in amounts or with methods neither approved nor supervised by medical professionals. Addiction is the continued use of a mood altering substance or behavior despite adverse dependency consequences, or a neurological impairment leading to such behaviors. The number in India is 3-5 million, 2 million of which are in Delhi alone. In India, there are one million heroin addicts, 2 million opium addicts and several million cannabis addicts. It may be mentioned that the ratio of drug abusers to alcoholics having serious alcohol abuse problems is 1 : 30. A Drug is any substance (other than food) that produces changes in the physical or mental functioning of an individual, and the Drug Use is taking a drug for medical purpose like treating an illness, protecting the body against the disease or to relieve pain or tension. Traditional definitions of addiction, with their criteria of physical dependence and withdrawal (and often an underlying tenor of depravity and sin) have been modified with increased understanding; with the introduction of new drugs, such as cocaine, that are psychologically or neuropsychologically addicting; and with the realization that its stereotypical application to opiate-drug users was invalid because many of them remain occasional users with no physical dependence.
To conclude, addiction is more often now defined by the continuing, compulsive nature of the drug use despite physical and/or psychological harm to the user and society and includes both licit and illicit drugs, and the term “substance abuse” is now frequently used because of the broad range of substances (including alcohol and inhalants) that can fit the addictive profile. There are many different types of drugs you should be aware of.

In this case, the slope is -4/5, so the slope of the perpendicular line would have the opposite sign, +, and is flipped, 5/4.
Therefore, the answer is a slope of 5/4, or answer choice A

Nayana: 28.76kg, Alka: 31.05kg, Asif: 32.36kg, Aman: 32.63kg
Answer:
Nayana: 28.76 kgAlka: 31.05 kgAman: 32.63 kgAsif: 32.63 kgStep-by-step explanation: Ascending means increasing, so arrange the weights from the smallest to the biggest.
The weights are all in kilograms (kg) so no conversion is needed. Just arrange the weights by the numbers, 28.76 is the smallest here, and 32.63 is the biggest number, and it is repeated, so in that case the order doesn't matter.
Aman can come before Asif and vice versa since they have the same weights.
The distance from the center of a circular tent to the tent’s edge is 50 feet. Kelly walked around the edge of the tent twice and then straight to the center of the tent. About how far did Kelly walk?
Answers
Answer:
678.32 feet
Step-by-step explanation:
Circumference=2π(radius)=2·π·50≈314.15927
314.15927·2=628.31854
628.31854+50=678.31854
Answer:
678 ft (nearest foot)
Step-by-step explanation:
The distance from the center of a circle its edge is its radius.
Given that the distance from the center of a circular tent to the tent’s edge is 50 ft then:
⇒ radius (r) = 50
The edge of a circle is its circumference
Circumference of a circle = [tex]2\pi r[/tex] (where r is the radius)
Therefore, the circumference of the tent is:
[tex]\implies 2 \cdot \pi \cdot 50=100\pi[/tex] ft
If Kelly walked around the edge of the tent twice, then walked straight to the center:
⇒ total distance walked = 2 × circumference + radius
= 2 × [tex]100\pi[/tex] + 50
= 678.3185307...
= 678 ft (nearest foot)
