Taking the square of both sides to change the subject of formula, the value of x is 16y² - 5

By transferring all other terms to the other side of an equation, changing the subject of a formula is a technique for manipulating algebra that is used to isolate a variable on one side of an equation. It is also referred to as "rearranging" or "transposing" a formula.

In order to simplify expressions, solve word problems, or solve equations, it can be helpful to change the subject of a formula.

It's crucial to keep in mind that altering a formula's subject can also alter the function's domain, which could be limited to a particular range of values.

In short, changing a formula's subject allows you to isolate a variable that is on one side of an equation by transferring all other terms to the opposite side of the equation. It's sometimes referred to as "rearranging" or "transposing" a formula. It's a helpful method for resolving equations.

In the given question;

Answer:

  x = ln(4) ≈ 1.3862944

Step-by-step explanation:

You apparently want the solution to the equation 2e^(2x) -2e^x -24 = 0.

This is effectively a quadratic in e^x. Dividing by 2, we get ...

  (e^x)^2 -(e^x) -12 = 0

Factoring gives ...

  ((e^x) -4)((e^x) +3) = 0

Solutions will be the values of x that make the factors zero.

  e^x -4 = 0   ⇒   e^x = 4   ⇒   x = ln(4)

  e^x +3 = 0   ⇒   e^x = -3   ⇒   x = ln(-3) . . . . not defined for real numbers

The only real solution is x = ln(4) ≈ 1.3862944.

Additional comment

In the complex numbers, the other solution is x = ln(-3) = ln(3) +πi.

The Range of the points (3, 2) and (-5, 2) is only the value of y = 2.

What is the domain and range of the function?

The domain of a function is the set of all input values (independent variable) for which the function is defined and produces a valid output (dependent variable). The range of a function is the set of all possible output values (dependent variable) that the function can produce for all valid input values (independent variable).

The domain and range of a set of points in a coordinate plane refer to the set of all possible x-values and y-values, respectively.

The domain of the points (3, 2) and (-5, 2) are all real numbers. So, the domain can be represented as (-inf, inf)

The coordinates of point B on the line is (-1/2, 19/4)

From the question, we have the following parameters that can be used in our computation:

Point A is at (-2,4) and point C is at (4,7).

Also, we have the ratio of AB to AC to be 1 : 3

The partition involves dividing the line into subsegments

This means that

(x, y) = (-2, 4) and (4, 7)

m : n = 1 : 3

The coordinates of the partition are calculated as:

Point = 1/(m + n) * (mx₂ + nx₁, my₂ + ny₁)

Substitute the known values in the above equation, so, we have the following representation

Point = 1/(1 + 3) * (1 * 4 + 3 * -2, 1 * 7 + 3 * 4)

Evaluate the products

So, we have the following representation

Point = 1/4 * (-2, 19)

Evaluate the quotients

Point = (-1/2, 19/4)

Hence, the coordinate of the partition is (x,y) = (-1/2, 19/4)

To conduct this simulation, we will first generate a random number between 0 and 1 for each of the four children in each trial. If the random number is less than 0.15, we will consider that child to have contracted the disease.Here is how we can do this using the random number table you provided:Trial 1:

Child 1: 0.14 (does not get the disease)

Child 2: 0.06 (gets the disease)

Child 3: 0.11 (does not get the disease)

Child 4: 0.13 (does not get the disease)Trial 2:

Child 1: 0.12 (does not get the disease)

Child 2: 0.08 (does not get the disease)

Child 3: 0.05 (gets the disease)

Child 4: 0.10 (does not get the disease)Trial 3:

Child 1: 0.09 (does not get the disease)

Child 2: 0.01 (gets the disease)

Child 3: 0.03 (gets the disease)

Child 4: 0.06 (gets the disease)...Trial 20:

Child 1: 0.14 (does not get the disease)

Child 2: 0.12 (does not get the disease)

Child 3: 0.05 (gets the disease)

Child 4: 0.07 (gets the disease)Based on this simulation, we can estimate the average number of children who will get the disease by taking the total number of children who got the disease across all 20 trials and dividing by the total number of trials. This comes out to be approximately 1.5 children.To calculate the probability of two of the children getting the disease, we count the number of trials where exactly two of the children got the disease, and divide by the total number of trials. In this simulation, this occurs in 5 trials out of 20, so the probability is 5/20 = 0.25.To calculate the probability of at least two of the children getting the disease, we count the number of trials where at least two of the children got the disease, and divide by the total number of trials. In this simulation, this occurs in 8 trials out of 20, so the probability is 8/20 = 0.4.

The table represents a linear function while the graph represents a nonlinear function.

Linear functions are functions where the relationship between the independent variable (x) and the dependent variable (y) is a straight line. This means that the graph of a linear function is a straight line and the slope (or rate of change) of the line is constant.

On the other hand, nonlinear functions are functions where the relationship between the independent variable (x) and the dependent variable (y) is not a straight line. The graph of a nonlinear function is often a curve, and the slope (or rate of change) of the curve can vary.

In the table, the rate of change is -3 and variables are moving constantly with one increasing and the other decreasing, which makes it a linear function.

The graph is a nonlinear function as the graph is a curve.

The general form of the equation Kareem can use to represent the data include the following: B. y = ab^x.

Generally speaking, an equation is a linear equation when the first difference between the y-values of an equation are the same. Additionally, an equation is an exponential equation when the common ratio between y-values of an equation are the same.

Furthermore, an equation is a quadratic equation when the second difference between the y-values of an equation are the same.

For the first difference between the y-values, we have:

First difference = 1/4 - 1/8 = 1/8

First difference = 1/2 - 1/4 = 1/4

Therefore, this equation is not a linear equation.

Next, we would determine the common ratio between y-values;

Common ratio = 1/4/(1/8) = 2

Common ratio = 1/2/(1/4) = 2

Therefore, this equation is not an exponential equation with the general form of y = ab^x.

The piecewise function is f(x) = {f(x)=2x, if x≤2

f(x) = {f(x)=2, if x>-4.

Piecewise functions are functions that have multiple pieces, or sections. They are defined piece by piece, with various functions defining each interval. Piecewise functions can be split into as many pieces as necessary. Each piece behaves differently based on the input function for that interval. Pieces may be single points, lines, or curves.

From the graph,

Domain of one part of line is x>-4 and domain of other part of the line is x≤2.

For increasing part of line m=4/2 =2

Which is intersecting y-axis at (0, 0), so y-intercept is c=0

Then, the function is y=2x+0

So, f(x)=2x

For the second part of line in III quadrant, slope=m=0

Substitute m=0 and (x, y)=(-1, 2) in y=mx+c, we get

2=0(-1)+c

c=2

So, equation is y=2

Now, the piecewise function is

f(x) = {f(x)=2x, if x≤2

3. j(x) = 3^(x + 6) - 2 : translation 6 units to the left and 2 units down

Translation say x units to the left is represented by positive x units while to the right is represented by negative x values. the left and right translation is restricted to the x values.

Translation say x units up is represented by positive x units while to the down is represented by negative x values. the top and down translation is restricted to the y values or the function itself.

Using the problem, comparing f(x) = 3^x and g(x) = 3^(x + 4) the difference is +4 hence it results to moving 4 units to the left

Comparing f(x) = 3^x and h(x) = (1/4)^(x - 5)

A factor of 12 is used to to make 1/4 equal to 3 since 1/4 * 12 = 3. this is called a vertical stretch

Step-by-step explanation:

You want a graph of the equation y = -5x +2.

The y-intercept is the point where the line crosses the y-axis. It is the value of y when x=0. In the equation, the y-intercept is the constant: +2.

The slope of the line is the coefficient of x. It is the ratio of "rise" to "run." The equation tells you the slope is -5. This means the line drops 5 units for each unit to the right.

Another point on the line will be (0, 2) +(1, -5) = (1, -3).

The line can be drawn through these points: (0, 2) and (1, -3).
