Select the angle(s) with measures that are greater than m<2

The solution to the inequality is x ≤ 1.

Inequality in mathematics is when two values are not equal. It can be expressed using symbols such as >, <, ≥ and ≤. This can be used to compare two values, express a range of values, or indicate that one value is greater or less than another. Inequality is a powerful tool for solving mathematical problems, as it can be used to deduce relationships between different variables.

To solve this inequality, we must first perform the operations on the left side of the equation to get an expression equal to 4. We can start by simplifying the fraction on the left side of the equation. We can multiply both the numerator and denominator by x, which will give us 5x - 3 = x + 2x. We can then add 3 to both sides to get 5x = 3 + 2x, which can then be simplified to 3x = 3. Finally, we can divide both sides by 3 to get x = 1. Therefore, the solution to the inequality is x ≤ 1.

Answer:

I don’t understand

Step-by-step explanation:

I had the same one

We have the following system of equations,

[tex]\left \{ {{y=x^2-1} \atop {y=5-x}} \right.[/tex]

We are asked to solve the system of equations using substitution.

What is substitution?

Substitution is a method of solving a system of equations where you solve for one of the equations (pick either equation) for one of the variables (pick one of the variables), then using this new equation to "substitute" back in to the other.

Given this set of equations, [tex]\left \{ {{y=x^2-1} \atop {y=5-x}} \right.[/tex], notice how both of the equations are already solved for the variable, [tex]y[/tex]. Since both these equations equal [tex]y[/tex], we can set them equal to each other and solve for, [tex]x[/tex].

[tex]\left \{ {{y=x^2-1} \atop {y=5-x}} \right.[/tex]

[tex]\Longrightarrow 5-x=x^2-1[/tex], substituted "[tex]5-x[/tex]" for [tex]y[/tex] into the top equation.

[tex]\Longrightarrow -x^2-x+6=0[/tex]

[tex]-1[\Longrightarrow -x^2-x+6=0][/tex]

[tex]\Longrightarrow x^2+x-6=0[/tex]

[tex]\Longrightarrow (x-2)(x+3)=0[/tex]

[tex]\Longrightarrow x=2 \ and \ x=-3[/tex]

Now take these values of x ([tex]x=2 \ and \ x=-3[/tex]) and plug them into either of the two original equations to solve for [tex]y[/tex].

When x=2:

[tex]y=5-x;x=2[/tex]

[tex]\Longrightarrow y=5-(2)[/tex]

[tex]\Longrightarrow y=3[/tex]

When x=-3:

[tex]y=5-x;x=-3[/tex]

[tex]\Longrightarrow y=5-(-3)[/tex]

[tex]\Longrightarrow y=5+3[/tex]

[tex]\Longrightarrow y=8[/tex]

Thus, we get two solutions to the given system of equations, (-3,8) & (2,3).

Answer:

24 years old

Step-by-step explanation:

Jim = 2x + 4

Mark = x

Sum of their ages = 34

2x + 4 + x = 34

3x = 30

3x / 3 = 30 / 3

x = 10

Mark = 10 years old

Jim = 2x + 4

= 2 ( 10 ) + 4

= 20 + 4

= 24

Therefore, Jim is 24 years old

Set y = 0 and solve for x

y = -1.25x + 15 = 0

1.25x = 15

x = 12

y = -0.75x + 12.75 = 0

0.75x = 12.75

A regression line is a line of​ means, and outliers have a big effect on the regression line.

Regression:

Regression is a statistical method used in finance, investing, and other disciplines that attempts to determine the strength and character of the relationship between a dependent variable (usually denoted by Y) and a set of other variables (called variables independent). Also known as simple regression or ordinary least squares (OLS), linear regression is the most common form of this technique. Linear regression establishes a linear relationship between two variables based on a line of best fit. So the linear regression is plotted with a straight line and the slope defines how changes in one variable affect changes in the other variable.

Regression Line:

Regression lines are very useful for the forecasting process. The purpose of this line is to describe the relationship between the dependent variable (variable Y) and one or more independent variables (variable X). Using the equation obtained from the regression line, the analyst can predict the future behavior of the dependent variable by entering different values ​​for the independent variable. Regression lines are widely used in the financial industry and in business in general.

The regression line formula is like the following:

Y = a + bX + u

The multiple regression formula looks like this:

Y = a + b₁X₁ + b₂X₂ + b₃X₃ + … + btXt +u.

Y is the dependent variable

X is the independent ones

a is the interception point

Since the given functions represent the cost for water and sewer separately, the total cost will be the sum of both.

For water usage, W(x) = 0.129x, where x is the number of 100-gallon units of water used. So, for 3800 gallons, we have:

W(x) = 0.129 * (3800/100) = $4.91 (rounded to the nearest cent)

For sewer usage, S(x) = 0.158x + 16.22, where x is the number of 100-gallon units of water used. So, for 3800 gallons, we have:

S(x) = 0.158 * (3800/100) + 16.22 = $21.12 (rounded to the nearest cent)

Therefore, the total amount a homeowner will pay for 3800 gallons of water and sewer usage for one month is:

Total cost = W(x) + S(x) = $4.91 + $21.12 = $26.03 (rounded to the nearest cent)

Each function has a range, codomain, and domain. The usual way to refer to a function is as f(x), where x is the input. A function is typically represented as y = f. (x).

Now in the given question ,

In particular, when y = 3, there are two possible values of x (x = 0 and x = 6), so (3, 0) and (3, 6) are two points on the graph of this equation. This violates the definition of a function, which states that for each input (in this case, y), there can only be one output (x).

The right choice for the equation is y+9=4(x-3). The Option B is correct..

An equation of the line refers to a linear equation having a degree of one. The equation contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

First thing to do is to solve each of these for y.  The first one is y=-4x-3; the second one is y=4x-21; the third one is y=4x+21; the fourth one is y=-4x+3.  From that, you can tell the positive slopes are found in the second and third equations.  

Those are the ones we will test now for the point (3, -9).  y=-9 and x=3, so let's fill in accordingly.  The second equation filled in is -9=4(3)-21.  

-9=12-21 and -9=-9.  So the second one works.  Just for the sake of completion, let's do the same with the third: -9=4(3)+21.  Does -9=12+21?  Of course, it doesn't. Our equation is the second one above, y+9=4(x-3).

The complete question is given below:

Select the equation that contains the point (3, -9), and in which the graph of the line has a positive slope.

y – 9 = –4(x + 3)

y + 9 = 4(x – 3)

y – 9 = 4(x + 3)

Let's denote the height of the school building as "h".

From the given information, we can draw a right triangle with the mirror on the ground, the top of the school building, and Aria's eyes as the vertices. The distance from Aria to the mirror is 1.25 meters, and the distance from the mirror to the school building is the unknown height "h". The distance from Aria's eyes to the mirror is 1.15 meters.

We can use similar triangles to set up an equation to solve for "h".

In the smaller triangle formed by Aria's eyes, the mirror, and the point directly below the top of the school building, we can see that:

h/1.25 = (h + 1.15)/11.45

This equation comes from the fact that the ratios of corresponding sides in similar triangles are equal.

Simplifying this equation gives us:
