The domain of the set of ordered pairs is {-6, 4, 5, -5, 8,} and the range is {7, -9, 2, 9, -8)} which are represented as a function.

The domain of a set of ordered pairs includes all possible x values of a function, and the range includes all possible y values of a set of ordered pairs.

Given the set of ordered pairs as :

{(-6,7),(4,-9),(5,2),(-5,9),(8,-8)}

Since the domain is the set containing the x-coordinates of all ordered pairs.

So the domain = {-6, 4, 5, -5, 8,}

And the range is the set containing the y-coordinates of all ordered pairs.

So the range = {7, -9, 2, 9, -8)}

Thus, the domain of the set of ordered pairs is {-6, 4, 5, -5, 8,} and the range is {7, -9, 2, 9, -8)}. which are represented as a function.

After 3.94 hours, the price of stock A and stock B will become same.

What do you mean by price?

Price can be defined as the amount of money that get paid for something.

Lets assume that after x hours the price of stock A is equal to price of stock B.

Since the price of stock A is increasing at rate of 0.11 per hour, so after x hours it will become:

$12.15 + 0.11x

Since the price of stock B is decreasing at rate of 0.08 per hour, so after x hours it will become:

$12.90 - 0.08x

Equating both price to get the value of x:

12.15 + 0.11x = 12.90 - 0.08x

(0.11+0.08)x = 12.90 - 12.15

x = 0.75/0.19

x = 3.94

Hence, after 3.94 hours the price will be same.

The dimensions of the corral of maximum area 80 x 160 feet

What is Area?

Area is a quantity that describes the extent of an area on a plane or curved surface. The area of ​​a planar region or planar region refers to the area of ​​a shape or planar layer, while surface area refers to the area of ​​an open surface or boundary of a three-dimensional object

Set each side perpendicular to the wall x

Parallel to the wall would be 320-2x

the area would be:

A(x) = x (320-2x)

A(x) = 320x-2x ^ 2

It is quadratic with a = -2 and b = 320

The largest area will happen when x = -b / 2a

= -320 / (- 2 * 2)

= 80 feet

so the width will be 80 feet and the length will be:

There is an infinite number of values that are in both the domain and range.

Here, we are given a function f(x) = m, where m is a real number greater than 0.

For a function, domain is all the input values that the function can take and range is all the output value that the function can take.

Here, all the x values are the domain and the set of all the values that m can take is the range of the function.

Here m can take all values except 0. Whereas there is no constraint on the x values.

Since the range can never have the value 0, options 1 and 2 are eliminated.

Clearly, there can be many values that are both in the domain and range of the given function.

Answer:

y = (5/2)x + 1 or

y =  2.5x + 1

Step-by-step explanation:

The slope-intercept form of the equation of a line is

y = mx + b

where m = slope, b = y-intercept

Slope = rise / run

where rise is the difference in y-values of two points on the line and run = difference in x values for the same two points'

Here the points are (2, 6) and (-2, -4)

rise = 6 - (-4) = 6 + 4 = 10

run = 2 - (-2) = 2 + 2 = 4

Slope = 10/4 = 5/2

Equation is

y = (5/2))x + b

To calculate b, plug in x, y values for (2, 6) to get
6 = (5/2) x 2 + b

6 = 5 + b

b = 6 - 5 = 1

Equation of line is

y = (5/2)x + 1

Why are theorems and postulates crucial in geometry?

The foundation of any mathematical system, including geometry, algebra, and trigonometry, are postulates and theorems. Mathematicians have created entire systems of mathematics by utilizing postulates to argue theorems that can then be proved by other theorems.

A statement that has been proven true or that can be proven is known as a theorem in mathematics. A logical argument that uses the deductive system's inference rules to establish a theorem is called a proof.

Using a system of equations, it is found that she bought:

To find how many bags of each candy she bought, we have to solve a system of equations, in which the variables are given as follows:

She bought three more bags of Reese's than lollipops, hence the first equation is:

y = x + 3.

She bought two fewer bags of Starbursts than lollipops, hence the second equation is:

z = x - 2.

Bags of lollipops cost $3.75 each, bags of Reese's cost $5.50 each and bags of Starbursts cost $4.25 each. She spent a total of $48.50, hence the third equation is:

3.75x + 5.5y + 4.25z = 48.50.

We have the variables y and z as a function of x, hence we can replace them into the third equation and solve for x as follows:

3.75x + 5.5(x + 3) + 4.25(x - 2) = 48.50

13.50x + 8.50 = 48.5.

13.50x = 40.50.

x = 40.50/13.50.

x = 3. (number of lollipops bags).

Hence the number of Reese's bags is:

y = x + 3 = 3 + 3 = 6.

Solution Below.

Step-by-step explanation:

This question tests on the concept of angle properties.

From the question above, we can form up an equation:

x + 2x + (x + 30) = 180 (Sum of angles in a triangle)

Now, we can solve for x to find the angles of each side.

[tex]x + 2 x + x + 30 = 180 \\ 4x + 30 \\ 4x = 150 \\ x = 37.5[/tex]

Now we can find the angles for each side:

x = 37.5

2x = 2 × 37.5 = 75

x + 30 = 37.5 + 30 = 67.5

Answer:

37.5, 75, and 67.5

Step-by-step explanation:

The angles of a triangle add up to 180 so everything inside is equal to 180.

180=x+2x+x+30, simplify

180=4x+30, subtract 30 on both sides

150=4x, divide 4 on each  side

37.5=x

solve now knowing x

x= 37.5

x+30= 67.5

2x= 75

Maggie made a mistake while combining similar terms of x using vertical angles; the result is -3x rather than 3x, hence the right answer is x = 9.

When two lines intersect, vertical angles are two angles that are opposed by the same vertex and are congruent, meaning they have the same measure.

The vertical angles for this issue are as follows:

4x + 2.

7x - 25.

Since they agree, the following equation may be used to determine the variable x:

4x + 2 = 7x - 25.

The following results from shifting all terms with x to the left side of the equality and all terms that are constant to the right side, with the opposite signal:

4x - 7x = -25 - 2

Combining similar phrases yields the following results:

-3x = -27.

Maggie made a mistake here since 4x - 7x = -3x, thus the proper answer is as follows:

3x = 27

x = 27/3

x = 9.

The given relation is a set of ordered pairs (x, y), where the first element is x and the second element is y.

To express the given relation as a table, enter the x-value of each ordered pair in the left column, and the corresponding y-value of each ordered pair in the right column:
