Answers

Answer 1
Answer:

Answer: The prove is mentioned below.

Step-by-step explanation:

Here the given functions are,

f(x)=(x-7)/(x+3)

g(x)=(-3x-7)/(x-1)

We have to prove that: f(g(x)) = x and g(f(x)) = x.

Since f(g(x))= ((-3x-7)/(x-1) -1)/((-3x-7)/(x-1) +3)

f(g(x))= (-3x-7-7x+7)/(-3x-7+3x-3)

f(g(x))= (-4x)/(-4)

f(g(x))= x

Now, g(f(x))= (-3(x-7)/(x+3) -7)/((x-7)/(x+3) -1)

g(f(x))= (-3x+21-7x-21)/(x-7-x-3)

g(f(x))= (-10x)/(-10)

g(f(x))= x

Answer 2
Answer:

Answer with Step-by-step explanation:

We are given that

f(x)=(x-7)/(x+3)

g(x)=(-3x-7)/(x-1)

We have to confirm that f and g are inverses by showing that f(g(x))=x=g(f(x))

f(g(x))=f((-3x-7)/(x-1))

f(g(x))=((-3x-7)/(x-1)-7)/((-3x-7)/(x-1)+3)

f(g(x))=((-3x-7-7x+7)/(x-1))/((-3x-7+3x-3)/(x-1))

f(g(x))=(-10x)/(x-1)* (x-1)/(-10)

f(g(x))=x

g(f(x))=g((x-7)/(x+3))

g(f(x))=(-3((x-7)/(x+3))-7)/((x-7)/(x+3)-1)

g(f(x))=((-3x+21-7x-21)/(x+3))/((x-7-x-3)/(x+3))

g(f(x))=((-10x)/(x+3))/((-10)/(x+3))

g(f(x))=(-10x)/(x+3)* (x+3)/(-10)=x

Hence, f(g(x))=g(f(x))=x

Therefore, f and g are inverses.

Apples are on sale for $1.20 a pound. Logan bought 3/4 of a pound. How much money did he spend on apples

Answers

What I did was turn ¾ in to a fraction (which is 75%) then turned it into a decimal (.75)
then I multiplied .75 by 1.20 and .9
So she spent 90 cents on apples
Hope I helped :)
(3)/(4) * 1.20 = (3.6)/(4) = \huge{\boxed{0.9}}

Answers

Since we are estimating the tax, we will round both the price and the tax to make it easy to perform the math mentally...

Round $97.95 to $100
Round 9.5% to 10%

10% of 100 =
.10 x 100 = 10

10 dollars is the best estimate for the tax.

Simplify an expression for the perimeter of the equilateral triangle shown below, in centimeters.Show your work AND Label your answer!
1.75x – 2

Answers

Answer:

1.75×2-2

Step-by-step explanation:

Final answer:

The perimeter of an equilateral triangle, with side length expressed as 1.75x – 2, can be found by tripling the side length expression. Thus, the simplified expression for the perimeter is 5.25x – 6 centimeters.

Explanation:

The question concerns a geometric concept - the perimeter of an equilateral triangle. An equilateral triangle is a triangle in which all three sides are equal. Therefore, to find the perimeter (the distance around the triangle), we simply add up the lengths of all the sides. Since all sides are equal for our triangle, we can multiply the length of one side by three to get the total perimeter.

The given expression for the side length of the equilateral triangle is 1.75x – 2. That's one side. Since an equilateral triangle has three sides of equal lengths, the expression for the perimeter will be 3 times the expression given for one side. Therefore, multiply the expression 1.75x – 2 by 3. So, P = 3(1.75x – 2). By distributing the 3, the simplified expression for the perimeter (P) is P = 5.25x – 6 (centimeters). Thus, the expression 5.25x – 6 simplifies the perimeter of the equilateral triangle in terms of x.

Discuss the impact of risky behaviour on an individual and community at large​

Answers

Answer:

Risky behavior refers to actions or decisions that have the potential to lead to negative outcomes or harm, either to oneself or to others. Such behavior can encompass a wide range of activities, including substance abuse, reckless driving, unsafe sexual practices, and engagement in criminal activities. The ramifications of risky behavior are multifaceted and can extend beyond the individual to impact the community at large. This discussion will delve into the consequences of risky behavior on both individuals and communities, highlighting the social, economic, and public health implications.

Impact on Individuals:

Risky behavior can have profound effects on the individuals involved. Physical and mental health risks are prevalent outcomes. For instance, substance abuse can lead to addiction, deteriorating health, and increased susceptibility to chronic diseases. Engaging in unsafe sexual practices can result in sexually transmitted infections and unintended pregnancies. Reckless driving might lead to severe injuries or fatalities. Moreover, risky behavior can exacerbate mental health issues, causing stress, anxiety, and depression due to the potential for adverse consequences and legal ramifications.

Impact on Communities:

The impact of risky behavior extends beyond the individual, affecting the community as a whole. One of the most prominent consequences is the strain on healthcare systems. Increased cases of injuries, illnesses, and mental health disorders stemming from risky behavior place additional burdens on healthcare facilities, leading to increased healthcare costs and resource allocation challenges. This, in turn, can lead to reduced quality of care for other community members.

Economically, risky behavior can result in significant financial burdens. For example, accidents caused by reckless driving can lead to property damage and medical expenses, burdening insurance companies and public resources. Criminal activities associated with risky behavior, such as theft or vandalism, can decrease property values and deter investment in the affected areas, ultimately impacting the economic vitality of the community.

From a social perspective, risky behavior can contribute to the erosion of social cohesion and trust within the community. Instances of criminal behavior or substance abuse can create feelings of insecurity and fear among residents. Additionally, the resulting strain on families and social networks due to the consequences of risky behavior can lead to breakdowns in relationships and support systems, further destabilizing the community fabric.

Public Health Implications:

Risky behavior also has significant public health implications. The spread of diseases, particularly through unsafe sexual practices or intravenous drug use, can lead to epidemics or localized outbreaks. This poses challenges for public health authorities in terms of disease prevention, containment, and treatment.

To mitigate the impact of risky behavior on individuals and communities, comprehensive strategies are required. These strategies could include educational campaigns aimed at raising awareness about the consequences of risky behavior, promoting healthy alternatives, and providing individuals with the necessary skills to make informed decisions. Furthermore, community-based support systems, access to mental health services, and rehabilitation programs can assist individuals in overcoming risky behavior patterns.

In conclusion, risky behavior has far-reaching implications, affecting not only the individuals engaging in such behavior but also the communities they are a part of. The physical, mental, economic, and social consequences underscore the importance of addressing risky behavior through holistic approaches that encompass education, healthcare, and community engagement. Efforts to curb risky behavior contribute not only to individual well-being but also to the overall health and vitality of communities.
