Since you know the value of n, you can substitute/plug it into the equation:

-4n² + 11          Plug in 3 into "n" since n = 3

-4(3)² + 11       Find 3² -->    3 x 3 = 9

-4(9) + 11       Multiply -4 and 9

-36 + 11

-25

Final answer:

To evaluate the expression -4n^2 + 11 for n = 3, substitute 3 for n and simplify to get -25.

Explanation:

To evaluate the expression -4n^2 + 11 when n = 3, you substitute the value of 3 for n into the expression and simplify.

First step: Substitute n with 3.

-4(3)^2 + 11

Second step: Calculate the square of 3.

-4(9) + 11

Third step: Multiply -4 by 9.

-36 + 11

Fourth step: Add 11 to -36.

The result is -25.

The value of the expression -4n^2 + 11 when n = 3 is -25.

Answer:

Let's solve the equation \( x - 1 = 5x + 2 \) to find the solutions:

1. **Subtract \(5x\) from both sides**:

\[

x - 5x - 1 = 2

\]

2. **Combine like terms**:

\[

-4x - 1 = 2

\]

3. **Add 1 to both sides**:

\[

-4x = 3

\]

4. **Divide both sides by -4**:

\[

x = -\frac{3}{4}

\]

So, the solution to the equation is \( x = -\frac{3}{4} \).

Now, let's check which of the options are solutions:

A. \( x \): Yes, \( x = -\frac{3}{4} \) is a solution.

B. \( x = \): No, this is not a valid format for a solution.

C. \( x = 2 \): No, \( x = -\frac{3}{4} \neq 2 \).

D. \( x - \): No, this is not a valid format for a solution.

Therefore, the correct answer is **A. \( x \)**.

The correct options are [tex]\frac{-3}{4}[/tex].

To find the solutions to the equation [tex]\( x - 1 = 5x + 2 \)[/tex], we first need to solve for [tex]\( x \)[/tex]. Let's do that step by step:

Start with the given equation:

[tex]\[ x - 1 = 5x + 2 \][/tex]

Move all terms involving [tex]\( x \)[/tex] to one side of the equation and constants to the other side. To do this, subtract [tex]\( x \)[/tex] from both sides and subtract [tex]\( 2 \)[/tex] from both sides:

[tex]\[ x - 1 - x - 2 = 5x + 2 - x - 2 \][/tex]

[tex]\[ -1 - 2 = 4x \][/tex]

[tex]\[ -3 = 4x \][/tex]

Now, divide both sides by [tex]\( 4 \)[/tex] to isolate [tex]\( x \)[/tex]:

[tex]\[ \frac{-3}{4} = \frac{4x}{4} \][/tex]

[tex]\[ -\frac{3}{4} = x \][/tex]

Answer:

(x - 1)² = 0

Step-by-step explanation:

Given

x² - 2x + 1 = 0 ( subtract 1 from both sides )

x² - 2x = - 1

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 1)x + 1 = - 1 + 1

(x - 1)² = 0

[tex]m = n + \frac{x}{p} \\ pm = pn + x \\ x = pm - pn \\ or \\ x = p(m - n)[/tex]

Answer:

[tex]x=p(m-n)[/tex]

Step-by-step explanation:

[tex]m=n+\frac{x}{p}[/tex]

Put n to the other side by subtraction.

[tex]m(-n)=n(-n)+\frac{x}{p}\\m-n=+\frac{x}{p}\\[/tex]

Use multiplication with 'p' to isolate x.

[tex](p)(m-n)=\frac{x}{p}(p)\\ p(m-n)=x[/tex]

x is now isolated.

[tex]x=p(m-n)[/tex]

Step-by-step explanation:

Okay, this is a fairly simple question.

First, you want to pick two pairs of coordinates (X,Y).

In this case, I chose (-3, 5) and (3, 1)

Now, you want to use the formula to find slope : y2-y1/x2-x1

-4 divided by 6

=-2/3  

Answer:

y = -2/3x + 3    pic below to show proof     i hope this helps!   :)

Step-by-step explanation:

looking at the photo this slope is negative

we can see 2 given points   (0,3) and (3,1)

y = +/- ?/?x +/- ?

from the point (0,3) we move down 2

y = -2/? x + ?

from the point that was moved down 2, we move over 3 to get to (3,1)             y = -2/3x + ?

the line crosses the 3 on the y-axis

y = -2/3x + 3

Answer:

Around o is the center point

The center point 0 is usually on a graph and you should use x axis if it doesn't say what axis o is. X + y are both 0 usually.

When you have 0 as a central point you are actually moving the shape at equality around just like you would with a pertractor.

So We have a same shape shown and you can do this by rotating the shape 180 so it looks upside down to how its shown originally or previously.

You then maneuver it around to the opposite graph diagonally opposite is most likely to be 180 degree.

So if it starts in x axis right side it will be in y axis diagonally to the left

You just have to show vertices or edges meet symmetrically from the 0 point like a mirror but also facing opposite direction as it has been rotated.

Step-by-step explanation:

The description of rotation of image of 180 degree around O is discussed below.

A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location.

Around o is the center point.

If it doesn't specify what the axis o is, use the x axis as the graph's centre point (0). Typically, (x+ y) are both 0.

The form at equality is actually moved around when 0 serves as the Centre, much like you would with a pertractor.

You can achieve this by turning the identical shape 180 degrees such that it appears upside down relative to how it was originally or previously displayed.

Hence, if it starts on the right side of the x axis, it will be on the left side of the y axis.

Thus, show how vertices or edges come together symmetrically from the origin, mirror-like, but also facing the other way because of rotation.

To solve for the most direct route home, the Pythagorean theorem is applied to the distances Maggie traveled east and north. Calculating the values yields a most direct route home distance of approximately 8.1 miles.

The student is asking about finding the most direct route home after traveling first to the east and then to the north. This scenario sets up a right-angled triangle where the legs represent the eastward and northward trips, and the hypotenuse represents the most direct route home. To find the length of this hypotenuse, which is the direct distance Maggie must travel to return home, we use the Pythagorean theorem:

a2 + b2 = c2

Where a = 4 miles (eastward distance), b = 7 miles (northward distance), and c is the direct distance home.

Calculating this gives us c = \2 + 72} = \.

Thus, c = approximately 8.1 miles (when rounded to the nearest tenth).

Maggie will travel approximately 8.1 miles to return home by the most direct route.

A rhombus is a type of polygon distinct from squares and rectangles due to its lack of right angles.

This description fits a geometric shape known as a rhombus. A rhombus is a type of polygon that is a quadrilateral with all four sides of equal length. Unlike a square, a rhombus does not have to have right angles, which distinguishes it from rectangles and squares. The sum of the interior angles in a quadrilateral is always 360°, a property that applies to rhombuses as well.

Step-by-step explanation:

The volume of a rectangular prism is denoted by the formula: [tex]V=lwh[/tex] , where [tex]l[/tex] is the length, w is the width, and h is the height.

Looking at the diagram, we can see that the length is 2 ft (so [tex]l[/tex] = 2), the width is 4 ft (so w = 4), and the height is 3 ft (so h = 3). Now, we can just plug in these values to find V, the volume:

[tex]V=lwh[/tex]

[tex]V=2*4*3=24[/tex]

Thus, the answer is 24 ft cubed.

A picture and the board it is mounted on are not mathematically similar because their corresponding sides do not have the same proportions, with the board generally having extra space around the picture that alters the length-to-width ratio. Additionally, artistic elements like tension and abstractness in images disrupt dimensional consistency that similarity requires.

To show that a picture and the board it is mounted on are not mathematically similar, we must understand similarity in a mathematical context. For two figures to be similar, they must have the same shape but not necessarily the same size, meaning their corresponding angles are equal, and their corresponding sides are in proportion. When we mount a picture on a board, the picture itself has dimensions that are different from that of the board - the board is usually larger to provide a border or frame around the picture. Since the additional border provided by the board changes the overall dimensions, the two objects cannot be considered mathematically similar.

The concept of similarity also involves dimensional consistency. If the picture and the board were to be similar, the ratio of the length to width in the picture would have to be the same as that of the board. However, in most scenarios, a picture needs to be mounted with additional space around it, thus altering the ratio.

Additionally, from an artistic point of view, tension within a painting or an abstract representation might disrupt the dimensional consistency that mathematical similarity requires. Various factors such as perspective can create a visual illusion that skews perceived dimensions, making it impossible for the two to be similar. When a picture includes a pattern that has a specific repetition with variation, it does not satisfy the conditions of mathematical similarity when placed on a uniform board.

Answer:

(7, 19)

Step-by-step explanation:

We know that we are talking about circle C, which means that the center is point C. Since the diameter is AB, that means that AB goes through the center C and that center C is the midpoint of the segment AB.

Say the coordinates of B are (x, y). We can use the Midpoint Theorem to figure out B. The Midpoint Theorem states that for two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex], the coordinates of the midpoint are: [tex](\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )[/tex].

Here, our two points are A(5, 1) and B(x, y). Then, the midpoint is: [tex](\frac{5+x}{2} ,\frac{1+y}{2} )[/tex]. We already know the midpoint is C(6, 10), so we can just set 6 equal to [tex]\frac{5+x}{2}[/tex] and set 10 equal to [tex]\frac{1+y}{2}[/tex]:

6 = [tex]\frac{5+x}{2}[/tex]  ⇒  12 = 5 + x  ⇒  x = 12 - 5 = 7

AND

10 = [tex]\frac{1+y}{2}[/tex]  ⇒  20 = 1 + y  ⇒  y = 20 - 1 = 19

So, the coordinates of B is: (7, 19).
