The width of the original rectangle must be less than twice the original height by a value of 6.

Let's assume the original width of the rectangle is represented by 'w', and the original height is represented by 'h'. We are given that the height is less than 10, so we can write this as h < 10.

According to the problem, when the width is increased by 2 and the height is decreased by 1, the new width becomes 'w + 2' and the new height becomes 'h - 1'. The area of the rectangle is given by the product of its width and height, so the new area can be expressed as (w + 2)(h - 1).

We are also told that the new area is increased by 4 compared to the original area. Therefore, we have the equation:

(w + 2)(h - 1) - wh = 4

Expanding and simplifying the equation:

wh + 2h - w - 2 - wh = 4

2h - w - 2 = 4

2h - w = 6

From this equation, we can observe that the difference between 2 times the original height and the original width is equal to 6.

Without further information, we cannot determine the exact value of the original width. However, based on the given equation, we can conclude that the original width of the rectangle must be less than twice the original height by a value of 6.

To solve the system of equations, you need to find the values of x and y that satisfy both equations simultaneously.

Start by setting the two given equations equal to each other:
-4x² + 7x + 1 = 3x + 2
Next, rearrange the equation to simplify it:
-4x² + 7x - 3x + 1 - 2 = 0
Combine like terms:
-4x² + 4x - 1 = 0
To solve this quadratic equation, you can use the quadratic formula:
x = (-b ± √(b² - 4ac)) / (2a)
In this case, a = -4, b = 4, and c = -1. Plug these values into the quadratic formula:
x = (-4 ± √(4² - 4(-4)(-1))) / (2(-4))
Simplifying further:
x = (-4 ± √(16 - 16)) / (-8)
x = (-4 ± √0) / (-8)
x = (-4 ± 0) / (-8)
x = -4 / -8
x = 0.5
Now that we have the value of x, substitute it back into one of the original equations to find y:
y = 3(0.5) + 2
y = 1.5 + 2
y = 3.5
Therefore, the solution to the system of equations is x = 0.5 and y = 3.5.

To solve the equation |3x-1| + 10 = 25, we need to isolate the absolute value term and then solve for x. Here's how:

1. Subtract 10 from both sides of the equation:
|3x-1| = 25 - 10
|3x-1| = 15

2. Now, we have two cases to consider:

  Case 1: 3x-1 is positive:
     In this case, we can drop the absolute value sign and rewrite the equation as:
     3x-1 = 15

  Case 2: 3x-1 is negative:
     In this case, we need to negate the absolute value term and rewrite the equation as:
     -(3x-1) = 15

3. Solve for x in each case:

  Case 1:
  3x-1 = 15
  Add 1 to both sides:
  3x = 15 + 1
  3x = 16
  Divide by 3:
  x = 16/3

  Case 2:
  -(3x-1) = 15
  Distribute the negative sign:
  -3x + 1 = 15
  Subtract 1 from both sides:
  -3x = 15 - 1
  -3x = 14
  Divide by -3:
  x = 14/-3

So, the solutions to the equation |3x-1| + 10 = 25 are x = 16/3 and x = 14/-3.

The corresponding point of f(x) if f(x) is symmetric to the origin is (-2, 3).

The given point is (2,-3) and we need to find the corresponding point of f(x) if f(x) is symmetric to the origin.

The point (x, y) is symmetric to the origin if the point (-x, -y) lies on the graph of the function. Using this fact, we can find the corresponding point of f(x) if f(x) is symmetric to the origin as follows:

Let (x, y) be the corresponding point on the graph of f(x) such that f(x) is symmetric to the origin. Then, (-x, -y) should also lie on the graph of f(x).

Given that (2, -3) lies on the graph of f(x). So, we can write: f(2) = -3

Also, since f(x) is symmetric to the origin, (-2, 3) should lie on the graph of f(x).

Hence, we have:f(-2) = 3

Therefore, the corresponding point of f(x) if f(x) is symmetric to the origin is (-2, 3).

There are 8 different ways to choose the leadership of the tribe.

To calculate the number of different ways to choose the leadership of the tribe, we need to consider the hierarchy and the number of positions to be filled.

First, we have one chief position. There is only one chief, so there is only one way to choose the chief.

Next, we have two supporting chief positions (supporting chief a and supporting chief

b). Since each supporting chief position can be filled independently, there are 2 ways to choose the supporting chiefs.

Lastly, for each supporting chief, we have two inferior officer positions. Since each supporting chief position has two inferior officer positions, there are 2 ways to choose the inferior officers for each supporting chief.

Therefore, the total number of different ways to choose the leadership of the tribe is calculated by multiplying the number of choices for each position:

1 (chief) * 2 (supporting chiefs) * 2 (inferior officers for each supporting chief) * 2 (inferior officers for the other supporting chief).

Multiplying these values together, we get: 1 * 2 * 2 * 2 = 8.

A one-to-one function is a function where each element in the domain is uniquely matched with an element in the range. This ensures that each input has a distinct output, and no two different inputs produce the same output.

A one-to-one function is a type of function where each element in the domain (x-values) is mapped to a unique element in the range (y-values). In other words, there is a distinct output for every input, and no two different inputs produce the same output.
To determine if a function is one-to-one, we can use the horizontal line test. This test involves drawing horizontal lines through the graph of the function. If every horizontal line intersects the graph at most once, then the function is one-to-one.
One way to prove that a function is one-to-one is to use algebraic methods. We can show that if two different inputs produce the same output, then the function is not one-to-one. Mathematically, this can be done by assuming that two inputs x1 and x2 produce the same output y, and then showing that x1 must equal x2. If we can prove that x1 equals x2, then the function is not one-to-one.

On the other hand, if no two different inputs produce the same output, then the function is one-to-one. This means that for any given value of y in the range, there is only one corresponding value of x in the domain.
In summary, a one-to-one function is a function where each element in the domain is uniquely matched with an element in the range. This ensures that each input has a distinct output, and no two different inputs produce the same output.

When a point with whole-number coordinates is reflected over the x-axis, the y-coordinate of the point changes sign from positive to negative or vice versa, and the x-coordinate stays the same.

Therefore, the distance between the original point and its reflection over the x-axis will always be twice the absolute value of the difference between the y-coordinates of the two points. Let's consider the point (2, 5) and its reflection over the x-axis.

The reflection of the point will be (2, -5). The distance between the two points can be found using the distance formula, which is the square root of the sum of the squares of the differences of the coordinates. Therefore, the distance between (2, 5) and (2, -5) is the square root of ((2-2)^2 + (5-(-5))^2), which simplifies to the square root of (0+100), which is 10. As we can see, the distance between the point and its reflection is an even number.In general, the distance between a point with whole-number coordinates and its reflection over the x-axis will always be an even number.

To find the perimeter of the fence that José will place around his house, we need to determine the length of all four sides of the fence.
Given that the shorter side of the fence is one-fourth (1/4) of the length of the longest side, which is 9.80m, we can calculate the length of the shorter side as follows:

Length of shorter side = (1/4) * 9.80m = 2.45m

Since the fence will form a rectangle around José's house, opposite sides will have the same length. Therefore, the length of the other shorter side will also be 2.45m.

To find the perimeter, we need to add up the lengths of all four sides of the fence:
Perimeter = Length of longer side + Length of shorter side + Length of longer side + Length of shorter side
        = 9.80m + 2.45m + 9.80m + 2.45m

To determine if the conjecture is true or false, we need to understand the definitions of supplementary angles and linear pairs.

Supplementary angles are two angles whose sum is 180 degrees. In other words, if ∠2 + ∠3 = 180°, then ∠2 and ∠3 are supplementary angles.

On the other hand, linear pairs are a specific case of adjacent angles, where the non-common sides of the angles form a straight line. In other words, if ∠2 and ∠3 share a common side and their non-common sides form a straight line, then ∠2 and ∠3 form a linear pair.

To give a counterexample, we can imagine two angles, ∠2 = 45° and ∠3 = 135°. The sum of these angles is 45° + 135° = 180°, so they are supplementary angles. However, their non-common sides do not form a straight line, so they do not form a linear pair.

The value of x is 2

Let's consider the lengths of the sides of the rectangle. We are given that PS has a length of 1+4x, and QR has a length of 3x + 3.

Since PS and QR are opposite sides of the rectangle, they must have the same length. We can set up an equation using this information:

1+4x = 3x + 3

To solve this equation for x, we can start by isolating the terms with x on one side of the equation. We can do this by subtracting 3x from both sides:

1+4x - 3x = 3x + 3 - 3x

This simplifies to:

1 + x = 3

Next, we want to isolate x, so we can solve for it. We can do this by subtracting 1 from both sides of the equation:

1 + x - 1 = 3 - 1

This simplifies to:

x = 2

Therefore, the value of x is 2.

By substituting the value of x back into the original expressions for the lengths of PS and QR, we can verify that both sides are indeed equal:

PS = 1 + 4(2) = 1 + 8 = 9

QR = 3(2) + 3 = 6 + 3 = 9

Since both PS and QR have a length of 9, which is the same value, our solution is correct.

Find the measure of x where we are given a rectangle with the following information PS = 1+4x and QR = 3x + 3.

The cartesian plane is divided into four regions, or quadrants. Each quadrant is labeled based on the signs of the x and y coordinates of points within it. The quadrants are referred to as the first quadrant, second quadrant, third quadrant, and fourth quadrant.

Each quadrant is defined by the signs of the x and y coordinates of points within it. The four quadrants are labeled as follows:

First Quadrant (+, +): This quadrant is located in the upper right portion of the Cartesian plane. It contains points with positive x-coordinates (to the right of the origin) and positive y-coordinates (above the origin). In this quadrant, both x and y values are positive.

Second Quadrant (-, +): Positioned in the upper left portion of the coordinate plane, this quadrant contains points with negative x-coordinates (to the left of the origin) and positive y-coordinates (above the origin). Here, x values are negative, while y values remain positive.

Third Quadrant (-, -): Found in the lower left part of the Cartesian plane, this quadrant consists of points with negative x-coordinates (to the left of the origin) and negative y-coordinates (below the origin). In the third quadrant, both x and y values are negative.

Fourth Quadrant (+, -): Situated in the lower right section of the coordinate plane, this quadrant contains points with positive x-coordinates (to the right of the origin) and negative y-coordinates (below the origin). Here, x values are positive, while y values are negative.

These quadrants provide a systematic way to locate and identify points in the Cartesian plane, facilitating mathematical operations, graphing functions, and analyzing geometric relationships. Each quadrant has its own unique characteristics and significance in various mathematical applications.

The correct answer is i. 33 ft

To find the height of the diving board, we need to consider the equation h(t) = -16.17t² + 13.2t + 33, where t represents the number of seconds after jumping.

The height of the diving board corresponds to the initial height when t = 0. In other words, we need to find h(0).

Plugging in t = 0 into the equation, we get:

h(0) = -16.17(0)² + 13.2(0) + 33

Since any number squared is still the same number, the first term becomes 0. The second term also becomes 0 when multiplied by 0. This leaves us with:

h(0) = 0 + 0 + 33

Simplifying further, we find that:

h(0) = 33

Therefore, the height of the diving board is 33 feet.

So, the correct answer is i. 33 ft.

Changing the signs of the zeros of a polynomial function corresponds to reflecting the graph of the function across the x-axis. This transformation is known as a vertical reflection or a reflection about the x-axis.

The zeros of a polynomial function are the x-values where the function intersects the x-axis. By changing the signs of these zeros, we are essentially flipping the points across the x-axis, which results in a vertical reflection of the graph.

This transformation affects the shape of the graph and the behavior of the function. For example, if the original function had a positive zero, after changing the sign, it will become a negative zero. Similarly, a negative zero will become positive. This reflection also changes the location of the turning points and the concavity of the function.

The y-intercept of g(x) is 4.

If the function f(x) = -4x - 2 is vertically translated 6 units up to g(x), the y-intercept of g(x) can be found by adding 6 to the y-intercept of f(x). The y-intercept of f(x) is the point where the graph of the function crosses the y-axis. In this case, it is the value of f(0).

f(0) = -4(0) - 2

f(0) = 0 - 2

f(0) = -2

To find the y-intercept of g(x), we add 6 to the y-intercept of f(x):

y-intercept of g(x) = y-intercept of f(x) + 6

y-intercept of g(x) = -2 + 6

y-intercept of g(x) = 4

Therefore, the y-intercept of g(x) is 4.
