Step-by-step explanation:

To solve the inequality, multiply both sides by (-5). The solution is b  ≤ 30 or (∞, 30]

Tips to solve linear inequalities:

Interval notation is often used for the solution(s). Recall the differences between a bracket [ or ], and a parenthesis (  or ). A bracket means the endpoint is included in the solution while a parenthesis means the endpoint is not included in the solution. Remember, infinity ∞ always use a parenthesis.

Example:  x ≥ 2 can be written as [2, ∞), while

                x > 0 is written as (2, ∞)

The given problem:

-b/5 ≥ -6

Notice that the variable, b, is already isolated on the left side. Multiply both sides by (-5) and flip the sign of the inequality ( since we multiply it by a negative number):

-b/5 . (-5) ≤ -6 . (-5)

b  ≤ 30

Using the interval notation, the solution is (∞, 30]

Step-by-step explanation:

Use angles on a straight line add up to 180°.

Triangle ABC is reflected across the y-axis. The two congruent triangles are mirrored across the y-axis, thus they are reflected.

6: Give the translation rule, any coordinate point will shift 4 units to the left and rise up 8 units.

The translation rule describes how each coordinate point of the original triangle ABC moves to form the reflected triangle after the reflection across the y-axis.

To reflect a triangle across the y-axis, all you need to do is change the sign of the x-coordinate while keeping  the y-coordinate the same. Using this rule, every point on the original triangle ABC will move 4 units to the left and go up 8 units to create the reflected triangle A'B'C' after the reflection.

The area and Perimeter of (ΔABC) are respectively; 17.5 square units and 24.16 units

The formula for the area of a triangle ABC with 3 coordinates is;

Area (ΔABC) = (¹/₂) |x₁(y₂ − y₃) + x₂(y₃ − y₁) + x₃(y₁ − y₂)|

The coordinates are;

(x₁, y₁) = (-6, 6)

(x₂, y₂) = (2, 3)

(x₃, y₃) = (-3, -2)

Thus;

Area (ΔABC) = (¹/₂) |-6(3 − (-2)) + 2(-2 − 6) + -3(3 − 6)|

Area (ΔABC) = (¹/₂)|-30 - 16 + 9|

Area (ΔABC) = ¹/₂ * |-35|

We are taking absolute value and so;

Area (ΔABC) = ¹/₂ * 35

Area (ΔABC) = 17.5 square units

To get the perimeter, we will use distance formula between two coordinates and we have;

AB = 8.544

BC = 7.071

AC = 8.544

Thus;

Perimeter = 2(8.544) + 7.071

Perimeter = 24.16 units

The perimeter of the rectangle is 4 + 4w, where w is the width of the rectangle.

In this question,

a rectangle has a width w

Let l be the length of the rectangle.

A  length that is two more than its width.

⇒ l = 2 + w

We know that the perimeter of the rectangle is P = 2 × (length + width)

So, for the length l = 2 + w and width w, the perimeter of the rectangle would be,

P = 2 × (w + (2 + w))

We simplify above expression.

P = 2 × (2 + 2w)

P = 4 + 4w

Therefore, the perimeter of the rectangle is 4 + 4w, where w is the width of the rectangle.

An ordinal scale provides more information than a nominal scale since values linked with an ordinal variable will be in natural order, whereas values connected with the nominal variable won't.

Ordinal variables as well as nominal variables are the two categories of variables listed here. This sort of variable cannot be submitted to the same forms of statistical tests as interval and ratio variables, hence it is crucial to be able to recognize them accurately. Both of these variables fall within the qualitative category. This contrasts with interval as well as rate variables, both of which are categorized as quantitative.

An illustration of an ordinal variable is a Likert scale with words for mood (such as joyful, neutral, or sad). An illustration of a nominal variable is the names of cities in the Canadian province of Alberta.

Based on the calculations, the number of student tickets and adult tickets that were sold are 225 tickets and 425 tickets respectively.

Given the following data:

Total ticket receipts = 650 tickets.

The price for a student ticket = $11.50.

The price for an adult ticket = $13.00.

Total revenue = $8,112.50.

An expression can be defined as a mathematical equation which is used to show the relationship existing between two or more variables and numerical quantities.

In order to determine the number of student tickets and adult tickets that were sold, we would translate the word problem into an algebraic expression as follows:

A + S = 650                              ......equation 1.

11.5S + 13A = 8,112.50              ......equation 2.

From eqn. 1, we have:

S = 650 - A                          ......equation 3.

Substituting eqn. 3 into eqn. 2, we have:

11.5(650 - A) + 13A = 8,112.50

7,475 - 11.5 A + 13A = 8,112.50

1.5A = 8,112.50 - 7,475

1.5A = 637.5

A = 637.5/1.5

A = 425 tickets.

For the student tickets, we have:

S = 650 - A

S = 650 - 425

S = 225 tickets.

Answer:

Function A is a function because the inputs on the table do not repeat any number, implying that each input has exactly one output. Function B is not a function because the inputs show that the number 6 is repeated. Function C is not a function because if we make a table, we can see that numbers repeat on the input, so Function C is not a function. Function D is a function because it would pass the vertical line test because no lines overlap with each other or have the input repeating.

Using the function concept, it is found that relations b and c does not represent a function.

A relation represents a function when each value of the input is mapped to only one value of the output.

On a graph, it means that each value of x is mapped to only one value of y, that is, there are no vertically aligned points on the graph.

For this problem, relation c does not represent a function, as there are multiple values of x are related to two values of y, and there are vertically aligned points on the graph.

In item b, when x = 6, there are two values of y, hence this is also not a function.

Answer:

m<1 = 111 degrees, m<2 = 69 degrees

Step-by-step explanation:

The measure of angles 1 and 2 are supplementary, (two angles adding up to 180 degrees). Using this, set up the equation:

x + 88 + 3x = 180  

4x = 108

x=23 degrees

Next, substitute 23 into the given angles:

m<1 = (23 + 88) = 111 degrees

m<2 = 23 * 3 = 69 degrees

Thus, m<1 = 111 degrees, m<2 = 69 degrees. Hope this helps
