Answer:

y = x - 6

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = \(\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\)

with (x₁, y₁ ) = (- 1, - 7 ) and (x₂, y₂ ) = (7, 1 )

m = \(\frac{1-(-7)}{7-(-1)}\) = \(\frac{1+7}{7+1}\) = \(\frac{8}{8}\) = 1 , then

y = x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (7, 1 ) , then

1 = 7 + c ⇒ c = 1 - 7 = - 6

y = x - 6 ← equation of line

The standard form polynomial expression represents the perimeter of this quadrilateral is 5x³ + 6x² + 2x - 11

Given a quadrilateral, we need to represent its perimeter with the help of a polynomial expression.A quadrilateral is a figure with four straight sides. Thus, to find its perimeter, we need to add up all of the lengths of its sides. For example, let's say that the sides of the quadrilateral are 4x³, 2x², x², 6x, -11, 3x², -4x, and 3.

So, we need to add up all of these terms. The final answer will be the polynomial expression representing the perimeter of the quadrilateral. Let's simplify the terms and then add them up to find the expression that represents the perimeter of the quadrilateral.4x³ + 2x²x² + 6x - 113x² - 4x + 3x³ - 2x

Simplifying the above expression, we get:4x³ + x³ + 2x² + x² + 3x² + 6x - 4x - 11 + 3xWe can further simplify this expression by adding like terms. Therefore, the standard form polynomial expression representing the perimeter of this quadrilateral is as follows:5x³ + 6x² + 2x - 11. Hence, the correct option is 5x³ + 6x² + 2x - 11.

Intervention is most likely to be included in the secondary and tertiary levels of prevention.

In the context of public health and healthcare, prevention is typically categorized into three levels: primary, secondary, and tertiary.

The primary level of prevention focuses on preventing the onset of diseases or health conditions before they occur. This is achieved through measures such as promoting healthy lifestyles, providing vaccinations, and implementing public health education campaigns. Intervention is less common at this level, as the main goal is to prevent the occurrence of the health issue in the first place.

The secondary level of prevention involves early detection and intervention to prevent the progression of a disease or health condition. This may include screenings, diagnostic tests, and prompt treatment. Intervention plays a crucial role at this level, as the focus is on identifying and addressing health issues at an early stage to minimize their impact.

The tertiary level of prevention aims to minimize the impact of an existing disease or health condition and prevent complications or further deterioration. Intervention is also prominent at this level, as it involves providing medical treatments, rehabilitation services, and ongoing care to manage the condition and improve quality of life.

The formula for calculating the effective annual rate of interest with quarterly compounding is:

(1 + r/4)^4 - 1 = A/P

where r is the quarterly interest rate, A is the final amount, and P is the principal.

In this case, P = $2,000, A = $3,000, and the time period is 7 years or 28 quarters.

So we have:

(1 + r/4)^4 - 1 = 3000/2000

(1 + r/4)^4 = 1.5

1 + r/4 = (1.5)^(1/4)

r/4 = (1.5)^(1/4) - 1

r = 4[(1.5)^(1/4) - 1]

To get the effective annual rate, we need to convert the quarterly rate to an annual rate by multiplying by 4:

effective annual rate = 4[(1.5)^(1/4) - 1] ≈ 8.84%

Therefore, the effective annual rate of interest at which $2,000 will grow to $3,000 in seven years if compounded quarterly is approximately 8.84%, rounded to 2 decimal places.

You have $2.30 and would like to buy some rice flour buy 9.2 ounces of rice flour with $2.30.

To arrive at this answer, we need to first convert the price per pound to price per ounce. There are 16 ounces in a pound, so the price per ounce is $4/16 = $0.25 per ounce.

Next, we divide the amount of money you have ($2.30) by the price per ounce ($0.25).

$2.30/$0.25 = 9.2 ounces.

Therefore, the conclusion is that you can buy 9.2 ounces of rice flour with $2.30.
Hi! I'm happy to help you with your question.

Answer:

The age of Jenny's mom is 40 % of age of Jenny's great-grandmother.  (Input: 40)

Step-by-step explanation:

The percentage needed is calculated by the following expression:

\(x = \frac{n_{M}}{n_{G}}\times 100\,\%\)

Where:

\(x\) - Percentage of Jenny's mother with respect to Jenny's great-grandmother, measured in percentage.

\(n_{M}\) - Age of Jenny's mother, measured in years.

\(n_{G}\) - Age of Jenny's great-grandmother, measured in years.

If we know that \(n_{M} = 36\,yr\) and \(n_{G} = 90\,yr\), the percentage is:

\(x = \frac{36\,yr}{90\,yr} \times 100\,\%\)

\(x = 40\,\%\)

The age of Jenny's mom is 40 % of age of Jenny's great-grandmother.

Answer:

The logo has an area of 5.7 cm².

Step-by-step explanation:

The area of the logo must be equal to the sum of the square's area and the triangle's one, therefore we will calculate each individually. The triangle is attached to the square, this means that its base has the same length as the side of the square.

\(square = side^2 = 2^2 = 4 \text{ cm}^2\)

\(triangle = \frac{b*h}{2} = \frac{2*1.7}{2} = 1.7 \text{ cm}^2\)

The total area of the figura is:

\(total = square + triangle = 4 + 1.7 = 5.7 \text{ cm}^2\)

The logo has an area of 5.7 cm².

Answer:

The correct answer is B. 200 and 100. When y is inversely proportional to x, it means that the ratio of x to y remains constant. In this case, when x = 20, y = 400, which means that the ratio of x to y is 20/400. Since the ratio is constant, we can use that ratio to find the values of y when x = 40 and x = 80. When x = 40, y = (20/400) x 40 = 200 and when x = 80, y = (20/400) x 80 = 100.

The false statement among the options provided is 2 ≥ 8. This statement claims that 2 is greater than or equal to 8, which is incorrect.

In reality, 2 is less than 8, so the statement is false.

The equation of the inverse function of the function f(x) = x + 5 is f'1(x) = x - 5

Inverse functions are the opposite of an original equation. This means that for a function f(x), the inverse of the function f(x) is f-(x); it also represents the opposite function

The function f(x) is given as

f(x) = x + 5

As a general rule, we start by writing f(x) as a variable (say f(x) = y).

So, the equation of the function becomes

y = x + 5

The next step is to switch/swap the positions of x and y in the above equation y = x + 5

The equation becomes

x = y + 5

The next step is to make y the subject of the formula in the above equation x = y + 5

The equation becomes

y = x - 5

This is done by subtracting 5 from both sides of the equation.

So, we have:

y = x - 5

Express as an inverse function

f'1(x) = x - 5

Hence, the inverse function of the function f(x) = x + 5 is f'1(x) = x - 5

By observation or by inspection, 7.40 appears the most, thus mode.

The value that appears most frequently in a data set is called the mode. One mode, several modes, or none at all may be present in a set of data. The mean, or average of a set, and the median, or middle value in a set, are two more common measurements of central tendency.

Data can be disseminated in statistics in a number of different ways. The traditional normal (bell-curve) distribution is the one that is referenced the most. The midpoint of this distribution, as well as some others, coincides with the peak frequency of observed values and is where the mean (average) value is located.

The mean, median, and mode all have the same values for such a distribution. This indicates that this value—the one that appears the most frequently in the data—is the average value, the middle value, and the mode.

When analyzing categorical data, such as automobile models or soda taste varieties, where a mathematical average median value based on ordering cannot be computed, mode is most helpful as a gauge of central tendency.
