Which of the following functions is graphed below?

Answer:

x = 1.5

y = 0.5

Step-by-step explanation:

y = −x + 2

y = 3x − 4

so

-x + 2 = 3x -4

2 + 4 = 3x + x

4x = 6

x = 1.5

then y = -x + 2 = -1.5 + 2 = 0.5

We have: y=−x+2 and y=3x−4

So: - x + 2 = 3x - 4

<=> - x - 3x = - 4 - 2

<=> - 4x = -6

<=> x = -6 ÷ 4

<=> x = -6/4 = -3/2

=> y = - x + 2 = - (-3/2) + 2 = 3/2 + 2 = 3/2 + 4/2 = 7/2 = 3,5

ANSWER: x = -3/2 = -1,5 and y = 3,5

ok done. Thank to me :>

The best way to solve this problem is to imagine the situation as follows: Suppose that each position (first, second and third) is a numbered box. (first is box number one, and so on).

Now, imagine that each student is a ball that is numbered from 1 up to 11.

The situation translates to calculate in how many different ways we can put a ball in each box, without putting 2 balls in each box. We have the following

To solve this, we will use the multiplication principle. This principle relays on multiplying the number of possibilites for each box. Consider the case in which we will fill the box number 1. We can choose any of the numbers, so we have 11 posibilites. Now, suppose that we chose one number for box 1, and now we want to fill box 2. Then, we will have 10 possibilites only, since we already picked one. In the same manner, to fill the third box we have 9 possibilities. So the total number of possibilites is the product of this three numbers. That is

True, The statement 5^7 = k is equivalent to log7 (5) = k, and the value of k is given by k = 5·log7(5)/log7(7)

The statement log7 (5) = k is equivalent to 5 = 7k, so k = log7(5)/log7(7). The equivalent form is k = log5/log7, where both the numerator and denominator are written in the same base log.

This can be seen by using the change of base formula which is a rule that simplifies writing logarithms with a base other than 10 or e.

This formula states that a logarithm with a base b can be converted to a logarithm with a base a using the following formula: loga(x) = logb(x) / logb(a).

For the case given in the question, we have:5·log7(5) = k·log7(7)Which can be rearranged to:log7(5^5) = log7(7^k). Then, using the fact that loga(x) = loga(y) if and only if x = y, we get:5^5 = 7^k

This means that k = log7(5^5)/log7(7), which simplifies to k = 5·log7(5)/log7(7).

Therefore, the statement 5^7 = k is equivalent to log7 (5) = k, and the value of k is given by k = 5·log7(5)/log7(7)

The value of c is approximately 1.1476.

To find the value of c for which the average value of the function f(x) = (9π/x^2)(cos(π/x)) on the interval (1,c) is -0.09, we need to calculate the average value of the function and solve for c.

The average value of a function f(x) on an interval [a, b] is given by:

Average value = (1 / (b - a)) * ∫[a, b] f(x) dx

In this case, we have the interval (1, c) and want the average value to be -0.09. So we can set up the equation:

-0.09 = (1 / (c - 1)) * ∫[1, c] [(9π/x^2) * cos(π/x)] dx

To solve this equation, we first evaluate the integral on the right side. The integral of the given function can be quite challenging to evaluate analytically. Therefore, we can use numerical methods or software to approximate the value of the integral.

Once we have the numerical approximation for the integral, we can solve for c by rearranging the equation:

(c - 1) = (1 / -0.09) * ∫[1, c] [(9π/x^2) * cos(π/x)] dx

(c - 1) = -1 / 0.09 * Approximated value of the integral

Finally, we can solve for c by adding 1 to both sides of the equation:

c = 1 + (-1 / 0.09) * Approximated value of the integral

Using numerical methods or software, we can compute the value of the integral and substitute it into the equation to find the approximate value of c, which is approximately 1.1476.

The domain for A is 0, 1, 2, 3 and the range is 0, 5, 10, 15

and the domain for B is 2, 2, 4, 4 and the range is 4, 3, 2, 1

Only A is a function because for the same input value in B, there is two different output values which is not possible.

Step-by-step explanation:

I just wanna let you know so you don't waste any more points for us, but the domain is the x-values/ input/ stuff on the left of a given point. The range is the y-values, the output, and the stuff on the right side of a given point. So on (1, 7) for example, the 1 would be the domain number and the 7 would be the range number.

The y-axis values are the output/range and the x-axis values are the input/domain.

In a simple linear regression model, the coefficient of the independent variable (x) in the estimated sample regression equation indicates the change in the predicted value of the dependent variable (y) when x increases by one unit. This coefficient is also known as the slope of the regression line. Therefore, to calculate the predicted value of y, we multiply the coefficient by the value of x and add the intercept.

In a simple linear regression model, the coefficient that indicates the change in the predicted value of y when x increases by one unit is the "slope coefficient" or the "regression coefficient" (usually denoted as b1). This coefficient represents the relationship between the independent variable x and the dependent variable y.

The linear regression equation is given as:

y = b0 + b1 * x

Where:
- y is the predicted value of the dependent variable
- b0 is the intercept coefficient (where the line intersects the y-axis)
- b1 is the slope coefficient (the change in y when x increases by one unit)
- x is the independent variable

In this equation, b1 indicates the change in the predicted value of y when x increases by one unit.

Answer:

m = 11

Step-by-step explanation:

-2(2 - 4m) = 6(m + 3)

Divide both sides by -2.

2 - 4m = -3(m + 3)

Distribute -3 on the left side.

2 - 4m = -3m - 9

Add 3m to both sides.

2 - m = -9

Subtract 2 from both sides.

-m = -11

Divide both sides by -1.

m = 11

The inequality expression 9|x - 8| < 36 when solved for x is 4 < x < 12

To solve the inequality 9|x - 8| < 36, we can divide both sides by 9:

|x - 8| < 4

This means that the distance between x and 8 is less than 4. So, the solution can be expressed in two parts:

x is less than 4 units away from 8 to the left:

x < 8 - 4 = 4

x is less than 4 units away from 8 to the right:

x > 8 + 4 = 12

Therefore, the solution is 4 < x < 12, or in interval notation: (4, 12).

Answer:

The slope formula is y2 - y1/x2 - x1.  

Step-by-step explanation:

First plug in x = 1, x = 2, and x = 3 in to the equation y = 4x to find the first 3 points(Like the first three are shown for the table.) which are (1, 4), (2, 8), and (3, 12).  

The slope of the table would be 9 - 3/3 - 1, after subtracting you get 6/2. You would then divide 6 by 2, which gives you 3. 3 is the slope of the table.

The slope of the equation goes through the same process. 12 - 4/3 - 1, after subtracting it's 8/2, and after dividing you get 4. The slope of the equation is 4.  

This means the equation has the greater slope.

The true statement about exponential smoothing where w is the smoothing parameter is chosen as the value that minimizes a selected measure of forecast accuracy such as the mean squared error (option d).

Exponential smoothing is a forecasting method that assigns weights to past observations based on the value of the smoothing parameter. The smoothing parameter, denoted as w, determines the rate at which past observations contribute to the forecast. By adjusting the value of w, the forecaster can control the emphasis placed on recent observations versus older observations.

The choice of the smoothing parameter is important in determining the accuracy of the forecast. In practice, the value of the smoothing parameter is selected to minimize a chosen measure of forecast accuracy, such as the mean squared error (MSE). The aim is to find the value of w that yields the most accurate forecast by minimizing the difference between the forecasted values and the actual values of the time series.

Therefore, statement d is true regarding the selection of the smoothing parameter in exponential smoothing.

Always check the quantity in each package to determine the appropriate number of hotdog bun packages needed for the given number of hotdog packages.
The dependent variable in this situation is the number of packages of hotdog buns needed, as it relies on the number of packages of hotdogs (the independent variable).

We want to know the dependent variable when considering the number of packages of hotdog buns needed for a certain number of packages of hotdogs.

Let me explain this relationship:
First, let's define the terms involved.

The dependent variable is the variable that depends on another variable (called the independent variable).

In this case, we are examining the relationship between the number of packages of hotdogs and the number of packages of hotdog buns needed.
The independent variable is the number of packages of hotdogs.

This is because the number of hotdog buns needed depends on the number of hotdogs you have.
The dependent variable, in this case, is the number of packages of hotdog buns needed.

This variable depends on the number of packages of hotdogs, as you need a certain amount of buns to accommodate the hotdogs.

To determine the relationship between these two variables, we would likely use a proportion or a ratio.

For example, if one package of hotdogs contains 10 hotdogs and one package of hotdog buns contains 10 buns, then the ratio is 1:1, meaning you need one package of hotdog buns for every package of hotdogs.
This relationship may vary depending on the number of hotdogs and buns in each package.

Remember to examine the proportion between the two variables to ensure you have the correct amount of buns for the hotdogs.
