This is the equation of the line in point-slope form, where the slope is 2 and the given point is (0, 12).

To find the equation of a line in point-slope form, we need a point on the line and the slope of the line.

Given the points (0, 12) and (-6, 0), we can calculate the slope using the formula:

slope = (y2 - y1) / (x2 - x1)

Using the coordinates (0, 12) as (x1, y1) and (-6, 0) as (x2, y2):

slope = (0 - 12) / (-6 - 0)

slope = -12 / -6

slope = 2

Now that we have the slope, we can use the point-slope form of the equation:

y - y1 = m(x - x1)

Using the point (0, 12) as (x1, y1) and the slope (m) as 2:

y - 12 = 2(x - 0)

Simplifying the equation:

y - 12 = 2x

This is the equation of the line in point-slope form, where the slope is 2 and the given point is (0, 12).

The range for the graph provided is from -10 to 10, inclusive.

To determine the range of the graph, we look at the vertical values or the y-values. The lowest y-value on the graph is -10, which corresponds to the point (-6, -10). The highest y-value on the graph is 10, which corresponds to the point (6, 10).

Therefore, the range of the graph is from -10 to 10, which means that all the y-values on the graph fall within this range. This indicates that the graph spans a vertical distance of 20 units, starting from -10 and ending at 10.

It's important to note that the range includes the minimum and maximum values attained by the graph. In this case, the graph reaches its lowest point at -10 and its highest point at 10.

Answer:

x = 2

Step-by-step explanation:

We are given the following equation:

[tex]\sqrt{x+7} -1=x[/tex], which we want to solve for x.

To do this, we should isolate the square root on one side, then square both sides. We can then solve the equation as normal, but then we have to check the domain in the end for any extraneous solutions.

Start by adding 1 to both sides.

[tex]\sqrt{x+7} -1=x[/tex]

            +1      +1

________________________

[tex]\sqrt{x+7} = x+1[/tex]

Now, square both sides.

[tex](\sqrt{x+7} )^2= (x+1)^2[/tex]

We get:

x + 7 = x² + 2x + 1

Subtract x + 7 from both sides.

x + 7 = x² + 2x + 1

-(x+7)   -(x+7)

________________________

0 = x² + x - 6

This can be factored to become:

0 = (x+3)(x-2)

Solve:

x+3 = 0

x = -3

x-2 = 0

x = 2

We get x = -3 and x = 2. However, we must check the domain.

Substitute -3 as x and 2 as x into the original equation.

We get:

[tex]\sqrt{-3+7} -1 = -3[/tex]

[tex]\sqrt{4} -1 = -3[/tex]

2 - 1 = -3

-1 = -3

This is an untrue statement, so x = -3 is an extraneous solution.

We also get:

[tex]\sqrt{2+7} -1 = 2[/tex]

[tex]\sqrt{9}-1=2[/tex]

3 - 1 = 2

2 = 2

This is a true statement, so x = 2 is a real solution.

Our only answer is x = 2.

Answer:

the approximate population of the city after 14 years will be 7.96 thousand residents.

Step-by-step explanation:

to calculate the approximate population of the city after 14 years, we need to take into account the annual growth rate.

Given that the city's population grows by around 420 persons each year, we can calculate the total growth over 14 years by multiplying the annual growth rate by the number of years:

14 years × 420 persons/year = 5,880 persons

To find the approximate population after 14 years, we add the total growth to the current population:

2.08 thousand + 5.88 thousand = 7.96 thousand

Answer:

the measure of < RST is 21.70 degrees.

Step-by-step explanation:

If < HIK and < RST are complementary angles, it means that the sum of their measures is 90 degrees.

Let's denote the measure of < RST as x.

Given that the measure of < HIK is 68.30 degrees, we can set up the following equation:

68.30 + x = 90

To solve for x, we subtract 68.30 from both sides:

x = 90 - 68.30

Calculating the value:

x = 21.70

For the data point (2, 5), the residual is 5 - 6 = -1. For the data point (3, 6), the residual is 6 - 8 = -2. For the data point (4, 11), the residual is 11 - 10 = 1. For the data point (5, 14), the residual is 14 - 12 = 2. For the data point (6, 15), the residual is 15 - 14 = 1.

To plot the residuals for the given linear function, we need to calculate the difference between the actual y-values of the data points and the corresponding predicted y-values based on the linear function.

Let's start by calculating the predicted y-values using the linear function y = 2x + 2 for each x-value in the dataset:

For x = 2, the predicted y-value is 2(2) + 2 = 6.

For x = 3, the predicted y-value is 2(3) + 2 = 8.

For x = 4, the predicted y-value is 2(4) + 2 = 10.

For x = 5, the predicted y-value is 2(5) + 2 = 12.

For x = 6, the predicted y-value is 2(6) + 2 = 14.

Now we can calculate the residuals by subtracting the predicted y-values from the actual y-values.

To visualize these residuals, we can create a scatter plot with the x-values on the horizontal axis and the residuals on the vertical axis. Each data point will represent the x-value from the dataset and its corresponding residual. The residuals can be either positive or negative, so we should include both sides of the vertical axis.

By plotting the residuals, we can observe the deviations between the actual y-values and the predicted y-values based on the linear function. This plot helps us assess how well the linear function fits the data and identify any patterns or trends in the residuals.

Step-by-step explanation:

The correct domain for the function y = √x is 0 ≤ x < ∞. The square root function is defined for non-negative real numbers, so x must be greater than or equal to 0 (0 ≤ x) to have a real value for the square root. The domain does not include negative values since the square root of a negative number is not a real number. The notation 0 ≤ x < ∞ represents all values of x that are greater than or equal to 0 and less than positive infinity.

The estimated population of the state in the year 2022 is 19,280,700 people.

The given equation represents the population of a certain state as a function of time, where p is the population in thousands of people and t is the number of years since 2010.

The equation is given as p = 80.7t + 18,312.3.

To estimate the population of the state, we substitute the value of t into the equation. For example, if we want to estimate the population in the year 2022 (12 years since 2010), we substitute t = 12 into the equation:

p = 80.7(12) + 18,312.3

= 968.4 + 18,312.3

= 19,280.7.

The estimated population of the state in the year 2022 is 19,280,700 people.

We can estimate the population for any given year by substituting the corresponding value of t into the equation.

It's important to note that the population is given in thousands of people, so we multiply the final result by 1,000 to obtain the population in actual numbers.

a. The interval of time between eruptions if the previous eruption lasted 4 minutes is 86.51 minutes.

b. The residual for this cycle is 2.07 minutes.

c. The interval of time between eruptions lasted for 2.07 minutes than the regression line equation predicted.

d. The slope of the regression line means that the interval of time between eruptions increases by 13.29 minutes for every additional minute of the previous eruption.

e. No, the value of the y-intercept doesn't have meaning in the context of the problem.

Based on the information provided above, the relationship between the duration of the previous eruption (x in minutes) and the interval of time between eruptions (y in minutes) is modeled by this regression line equation:

ÿ = 33.35 + 13.29x

Part a.

When x = 4 minutes, the value of is given by:

ÿ = 33.35 + 13.29(4)

ÿ = 86.51 minutes.

Part b.

The residual for the given cycle can be calculated as follows;

Residual = y - ÿ

Residual = 62 - (33.35 + 13.29(2))

Residual = 62 - 59.93

Residual = 2.07 minutes.

Part c.

Based on the calculation above, we can logically deduce that the interval of time between eruptions lasted for 2.07 minutes than the equation of regression line predicted.

Part d.

The slope of the regression line is equal to 13.29 and it implies that the interval of time between eruptions increases by 13.29 minutes for every additional minute of the previous eruption.

Part e.

In the context of the problem, we can logically deduce that the value of the y-intercept doesn't have any meaning because the duration of the previous eruption cannot be equal to 0 minutes.

Answer:

There are three main ways to prove that two triangles are congruent using transformations:

1. Congruence by translation: If there is a translation that maps one triangle onto the other, then the triangles are congruent.

2. Congruence by reflection: If there is a line of reflection that maps one triangle onto the other, then the triangles are congruent.

3. Congruence by rotation: If there is a rotation that maps one triangle onto the other, then the triangles are congruent.

In order to use these transformations to prove congruence, you need to show that all corresponding parts (angles and sides) are congruent after the transformation is applied. This can be done either algebraically, using coordinate geometry, or by providing a clear visual representation of the transformations that are applied.

For example, if you want to prove that two triangles, ABC and DEF, are congruent by translation, you need to show that there is a vector that, when added to the coordinates of any point on triangle ABC, produces the coordinates of the corresponding point on triangle DEF. Once you have shown that all three sides and angles are congruent after the translation, you can conclude that the triangles are congruent.

His total expenditure is $100. After that, he sold the CD player for $125. As a result, he earned $25.

Al initially bought a CD player for $100 and then sold it for $125. After that, he bought it back for $150 and later sold it for $175. The question is whether Al made money, lost money, or broke even.

Let's examine the transactions in more detail to determine the answer.

Initially, Al bought the CD player for $100.

Now his total income is $25 and his expenditure remains at $100. Next, he purchased the same CD player again for $150. This adds to his expenditure, which is now $250.

Later, he sold the CD player for $175, which means he earned another $25, bringing his total income to $50 (i.e., $25 from the first sale and $25 from the second sale).

Since Al's total expenditure was $250 and his total income was $50, he lost money. He spent more than he earned.

He sold the CD player twice and earned a total of $50, which is less than what he spent on the CD player, which was $250. Al had a net loss of $200 ($250 - $50). Therefore, he lost money.

The correct answer is b. Extrapolation since 20 is within the range.

In this scenario, finding the best predicted value for x = 20 would be an example of extrapolation. Extrapolation involves estimating values outside the given range of data based on the trend or pattern observed within the existing data.

Given the data set: 4, 10, 2, 18, 15, we can see that the values provided are not in any particular order. To perform extrapolation, it is generally helpful to first examine the trend or pattern within the data. However, without additional information or context, it is difficult to determine the underlying trend in this case.

Since the given data set does not explicitly indicate any pattern or trend, any estimation made for x = 20 would be considered extrapolation. Extrapolation involves projecting or extending the existing trend or pattern beyond the known data points. In this case, the value of 20 falls outside the range of the given data set, so estimating its corresponding value would require extending the trend beyond the known data points.

Consequently, the appropriate response is b. Extrapolation since 20 is within the range.
