Shaded region represents the set of all points (x, y) that satisfy both inequalities y > -x-2 and y < -5x+2.

a relationship between two expressions or values that are not equal to each other is called 'inequality.

First, we graph the lines y = -x-2 and y = -5x+2 using their y-intercepts and slopes.

The line y = -x-2 has a y-intercept of -2 and a slope of -1, which means that for every increase of 1 in x, y decreases by 1.

The line y = -5x+2 has a y-intercept of 2 and a slope of -5, which means that for every increase of 1 in x, y decreases by 5.

The shaded region represents the set of all points (x, y) that satisfy both inequalities y > -x-2 and y < -5x+2.

Hence, shaded region represents the set of all points (x, y) that satisfy both inequalities y > -x-2 and y < -5x+2.

Answer: 6 oz

Step by step:

5 < 6

Did i miss something?

Answer: 6 oz. is greater than 5 oz.

Step-by-step explanation:

Imagine you had 6 dogs. Now let's say that one passed away due to a car accident. Now you have 5 dogs. We can say by the fundamental theorem of common sense that you indeed did have more dogs before that accident. Using that logic in the grand scheme of metrics, we can say that 6oz is larger as a value than 5oz.

The vertex of the parabola y=-x^(2)-14x-49 is located at (-7,0). And there is only one x-intercept, which is (-7,0)

The vertex of a parabola is the point where the parabola changes direction. The vertex is found by completing the square for the quadratic equation. The x-coordinate of the vertex is given by the formula x = -b/2a, where a and b are the coefficients of the quadratic equation. The y-coordinate of the vertex is found by substituting the x-coordinate of the vertex into the equation for y.

For the given parabola, y=-x^(2)-14x-49, the coefficients are a=-1 and b=-14.

The x-coordinate of the vertex is:
x = -b/2a = -(-14)/(2*(-1)) = -7

The y-coordinate of the vertex is:
y = -(-7)^(2)-14(-7)-49 = -49+98-49 = 0

Therefore, the vertex of the parabola is (-7,0).

To find the x-intercepts, we need to solve the equation for when y=0:
0 = -x^(2)-14x-49
0 = (x+7)(x+7)
x = -7

Since the equation has only one solution, there is only one x-intercept, which is (-7,0). This is also the vertex of the parabola.

The graph of this function is a sine curve with amplitude 3√2 and phase shift π/4.

The k cos(ϕ) would be 3 and k sin(ϕ) would be 3.

The combined sound is given by:

f(t) = f1(t) + f2(t)

f(t) = 3 sin(t) + 3 cos(t)

To find k and ϕ, we can use the following trigonometric identity:

k sin(t + ϕ) = k sin(t) cos(ϕ) + k cos(t) sin(ϕ)

Let V be a finite-dimensional vector space and let S1 and S2 be two bases of V. To show that S1 and S2 have the same number of elements, we will assume, without loss of generality, that S1 has more elements than S2, i.e., n > m. We will then derive a contradiction.

Since S1 is a basis of V, every vector in V can be expressed as a linear combination of the vectors in S1. In particular, for each j = 1, 2, ..., m, we can express βj as a linear combination of the vectors in S1:

βj = c1,jα1 + c2,jα2 + ... + cn,jαn

where c1,j, c2,j, ..., cn,j are scalars. We can write this in matrix form as

| β1 | | c1,1 c1,2 ... c1,m | | α1 |

| β2 | | c2,1 c2,2 ... c2,m | | α2 |

| ... | = | ... ... ... ... | * | ... |

| βm | | cm,1 cm,2 ... cm,m | | αn |

where the matrix on the right is the matrix whose columns are the vectors in S1, and the matrix on the left is the matrix whose columns are the vectors in S2.

Since S2 is also a basis of V, the matrix on the left is invertible. Therefore, we can multiply both sides of the equation by the inverse of the matrix on the left, giving

| α1 | | b1,1 b1,2 ... b1,m | | β1 |

| α2 | | b2,1 b2,2 ... b2,m | | β2 |

| ... | = | ... ... ... ... | * | ... |

| αn | | bn,1 bn,2 ... bn,m | | βm |

where b1,j, b2,j, ..., bn,j are scalars.

Now consider the determinant of the matrix on the left-hand side of this equation. Since this matrix is obtained by multiplying the matrix whose columns are the vectors in S2 by the inverse of the matrix whose columns are the vectors in S1, its determinant is equal to the product of the determinants of these two matrices:

det([α1 α2 ... αn]) * det([β1 β2 ... βm]^-1) = det([α1 α2 ... αn] [β1 β2 ... βm]^-1)

The left-hand side is nonzero, since S1 and S2 are both bases of V and therefore their vectors are linearly independent, so the determinant of each matrix is nonzero. However, the right-hand side is zero, since the product of the two matrices on the right-hand side is the identity matrix, and the determinant of the identity matrix is 1.

This is a contradiction, so our assumption that S1 has more elements than S2 must be false. Therefore, S1 and S2 have the same number of elements, and the proof is complete.

A1. We can use Gaussian Elimination to determine if the system has a unique solution, infinite many solutions, or no solution. Gaussian Elimination is a method of solving linear equations by reducing a system of equations to a simpler form.

First, we need to write the system of equations in matrix form:

| 2 4 3 | | x1 | = | f |
| 1 d -3 | | x2 | = | g |
| 1 2 c | | x3 | = | h |

Next, we will use Gaussian Elimination to reduce the matrix to row echelon form:

| 1 2 c | | x1 | = | h |
| 0 (d-2) (-3-c) | | x2 | = | (g-h) |
| 0 (4-2d) (3-2c) | | x3 | = | (f-2h) |

Now, we can check for the conditions that determine the number of solutions:

1. If the rank of the coefficient matrix is less than the rank of the augmented matrix, then the system has no solution.

2. If the rank of the coefficient matrix is equal to the rank of the augmented matrix, and the rank is equal to the number of variables, then the system has a unique solution.

3. If the rank of the coefficient matrix is equal to the rank of the augmented matrix, and the rank is less than the number of variables, then the system has infinite many solutions.

In this case, if (d-2) ≠ 0 and (4-2d) ≠ 0, then the system has a unique solution. If (d-2) = 0 and (4-2d) = 0, then the system has infinite many solutions. If (d-2) = 0 and (4-2d) ≠ 0, or (d-2) ≠ 0 and (4-2d) = 0, then the system has no solution.

Therefore, we can find a relation which gives a unique solution or infinite many solutions by using Gaussian Elimination and checking the conditions for the number of solutions.

The value of k for which both 6x² - 17x + 12 = 0 and 3x² - 2x + k = 0 have a common root is k = 1/3.

A quadratic equation is a second-order polynomial equation in a single variable x , ax2+bx+c=0. with a ≠ 0 .

The discriminant of the first quadratic equation, 6x² - 17x + 12 = 0, is:

b² - 4ac = (-17)² - 4(6)(12) = 1

Since the discriminant is not zero, this quadratic equation does not share a common root with any other equation.

For the second quadratic equation, 3x² - 2x + k = 0, to have a common root with 6x² - 17x + 12 = 0, its discriminant must be zero.

The discriminant of the second quadratic equation is:

b² - 4ac = (-2)² - 4(3)(k) = 4 - 12k

To find the values of k that make the discriminant equal to zero, we solve the equation:

4 - 12k = 0

Simplifying, we get:

12k = 4

k = 4/12

k = 1/3

Therefore, the value of k for which both 6x² - 17x + 12 = 0 and 3x² - 2x + k = 0 have a common root is k = 1/3.

Answer:

a. Let's denote the width of the property as "w". According to the problem, the length of the property is three times the width, so we can represent the length as "3w".

To find the equation that can be used to solve for the length and width, we can use the formula for the perimeter of a rectangle:

Perimeter = 2(length + width)

Since we know the perimeter (5,280 feet), and we have expressions for the length and width, we can substitute these values into the formula and solve for the variables:

2(3w + w) = 5,280

2(4w) = 5,280

8w = 5,280

w = 660

Therefore, the width of the property is 660 feet, and the length is 3 times the width, or 1,980 feet.

b. To check that these values are correct, we can substitute them back into the formula for perimeter and make sure it equals 5,280:

2(1,980 + 660) = 5,280

This is true, so we can be confident that the width of the property is 660 feet and the length is 1,980 feet.

The answer is yes, more than one triangle can be formed using the three angle measures of triangle QPC. This is because the sum of the three angle measures of a triangle is always equal to 180 degrees.

A triangle is a three-sided geometric figure, consisting of three straight lines connecting three vertices. It is one of the most fundamental shapes in geometry and is used as the basis for a variety of mathematical concepts.

If two angle measures are given, any third angle measure between 0 and 180 degrees can be chosen to form a triangle. Thus, if two angle measures of triangle QPC are given, any third angle measure between 0 and 180 degrees can be used to form a triangle.

For example, if two angle measures of triangle QPC are 45 degrees and 65 degrees, then any third angle measure between 0 and 180 degrees can be chosen to form a triangle. Thus, if the third angle measure chosen is 70 degrees, then a triangle with three angle measures of 45 degrees, 65 degrees and 70 degrees can be formed. Similarly, if the third angle measure chosen is 30 degrees, then a triangle with three angle measures of 45 degrees, 65 degrees and 30 degrees can be formed.

Thus, it can be concluded that more than one triangle can be formed using the three angle measures of triangle QPC.
