The solutions for the given quadratic equation are -0.15 and -5.85.

The solutions to the quadratic equation are the values of the unknown variable x, which satisfy the equation. These solutions are called roots or zeros of quadratic equations. The roots of any polynomial are the solutions for the given equation.

The given quadratic equation is x²+6x+1=0.

Compare x²+6x+1=0 with ax²+bx+c=0, we get a=1, b=6 and c=1

Use x = [-b ± √(b² - 4ac)]/2a to find the solution. That is,

x = [-6 ± √(6² - 4×1×1)]/2×1

x= (-6 ± √32)/2

x=(-6 ± 5.7)/2

x= -0.3/2 and -11.7/2

x= -0.15 and -5.85

Therefore, the solutions for the given quadratic equation are -0.15 and -5.85.

The required inequality is x > -22/7 which is equivalent to the given inequality.

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

The inequality is given in the question, as follows:

-4(x+7) < 3(x-2)

We have to determine the equivalent inequality to the given inequality

As per the question, we have

-4(x+7) < 3(x-2)

Apply the distributive property on both sides,

-4x - 28 < 3x - 6

Rearrange likewise terms,

The equation representing the trend line for the data and used to make predictions is a regression equation.

A trend line, also known as a regression line, is a line that represents the relationship between two variables. In this case, the two variables are the time elapsed and the value of the house. By fitting a regression line to the data, it becomes possible to make predictions about the value of the house at any given time in the future.

The type of regression used to model the trend line depends on the nature of the relationship between the two variables. A linear regression is often used when the relationship is approximately linear. In such a case, the regression equation has the form Y = a + bX, where Y is the value of the house, X is the time elapsed, a is the intercept, and b is the slope of the line.

This question cannot be answered without any data because the equation representing the trend line for the data and used to make predictions depends on the specific data being analyzed.

Without the data, it is impossible to determine the relationship between the two variables, which is necessary for finding the appropriate regression equation to model the trend line.

GDP, turnover, wages, and other values' growth rates indicate how much something has changed over time (month, quarter, year). It is typically stated as a percentage.

A value's growth rate (such as GDP, turnover, earnings, etc.) gauges how much it has changed over time (month, quarter, year). It is quite frequently expressed as a percentage.

Growth rates are used to quantify the annual percentage change in a variable. If a variable has a positive growth rate, it is increasing over time; if it has a negative growth rate, it is declining over time. Growth rates can be helpful in evaluating a company's performance and forecasting future performance.

f(x) = 2 * (1.25)^x

This has the shape of

y = a b^x

where b is the growth rate multiplied by one

B = 1.25 + growth rate = 1

1.25 = 1 + the growth rate

Answer:

75

Step-by-step explanation:

A straight line is 180 degrees. Therefore, ACB = ACD - DCB

= ACB = 180 - 105 = 75

The length of the rectangle is 15 units. We can calculate this by using the formula for the area of a rectangle, which is length times width. So, 180 = 12 x length. Solving for length, we get 15.

Answer:

15

Step-by-step explanation:

area of rectangle: base times height or width times length, so;

180(area)=12(width) times height, to find the length divide area by width

180/12=15

The unknown angle in the triangle is as follows:

∠E = 60 degrees.

The sum of angles in a triangle is 180 degrees. The angle ∠E can be found using exterior angle theorem.

Therefore, the exterior angle theorem states that the measure of an exterior angle is equal to the sum of the measures of the two remote interior angles of the triangle.

Hence,

120 = ∠C + ∠E

ΔEBC is an isosceles triangle. Therefore, the base angles are congruent.

∠B ≅ ∠C

∠C = 60°

Therefore,

∠E = 120 - 60

∠E = 60 degrees

Quantities and their variants, equations and associated structures, shapes and their positions, and locations where they are found are all included in the study of mathematics. The link between a collection of inputs, each of which has a corresponding output, is referred to as a "function." A function is a dynamic relationship between inputs and outputs in which each input produces a single, unique result. Each function has a designated area and only needs a tiny area, or scope.

Here,

As a result, h(x) = x2-10x+21 A(x) =y/x =-1 x 10 A(x)=?

A(x) = y/x =h(x-g)-h(x)/g

A graph is inverse if it is the reflection of the original graph across the line y = x.

Meaning, if you were to put a mirror along the line y = x, the original graph would be reflected onto the inverse graph.

To determine if a graph is the inverse of another graph, we can check the following:

It is important to note that not every function has an inverse function. The function needs to be one-to-one, which means that for every unique output, there must be a unique input.

In summary, a graph is the inverse of another graph if the x- and y-coordinates of the points on the original graph are the y- and x-coordinates of the corresponding points on the inverse graph, respectively and the graph is symmetric about the line y = x.

In Mathematics, a point of intersection is the location on a graph where two (2) lines intersect, or cross each other, which is typically represented as an ordered pair containing the point that corresponds to the x-axis and y-axis on a cartesian coordinate.

The solution to the system of equations is

A system of equations is a pair of two linear equations

Given the system of equations

y = -x/3 - 1 and

y = 2x + 2

We proceed to solve the system of equations as follows.

Since we have the equations

y = -x/3 - 1 and

y = 2x + 2

Eqating both expressions, we have that

-x/3 - 1 = 2x + 2

adding 1 from both sides, we have

-x/3 - 1 + 1 = 2x + 2 + 1

-x/3 + 0 = 2x + 3

-x/3 = 2x + 3

Subtracting 2x from both sides, we have that

-x/3 - 2x = 2x - 2x + 3

(-x - 6x)/3 = 0 + 3

-7x/3 = 3

Multiplying both sides by 3, we have

-7x = 3 × 3

-7x = 9

Dividing both sides by -7, we have

x = 9/-7

x = -9/7

Substituting x = -9/7 into y = 2x + 2, we have that

y = 2x + 2

y = 2(-9/7) + 2

= -18/7 + 2

= (-18 + 14)/7

The number of the last locker the student opens is 1996.

The student starts by opening locker 1 and then skips one, opens the next one, skips one, and so on. The pattern of open and closed lockers can be thought of as a binary sequence where open lockers are represented by 1 and closed lockers are represented by 0. The student's actions can be thought of as a process of repeatedly dividing the lockers into smaller groups and reversing the order of the open and closed lockers within each group.

The first time the student reaches the end of the hall, the lockers are in the following order:

0001 1110 1111 0010 0101 1010 0101 0010

When the student turns around and starts back, the first locker he encounters is the one that was not opened the first time. The student then opens every other locker, skipping the ones that were already opened. This results in the following order:

0110 1010 0101 0010

The student then continues this process of dividing the lockers into smaller groups and reversing the order of the open and closed lockers within each group. After a few iterations, the student ends up with only one locker left, which is the last one he opens. The number of this locker is represented by the binary number, which is the reverse of the binary representation of 1996. Therefore, the number of the last locker the student opens is 1996.
