Ashley thinks the lines are parallel is correct. Meanwhile, Alexandro is wrong, he thinks the lines are neither.

The two lines, y = -2x + 7 and 6x + 3y = 21, are parallel because they have the same slope.

To determine if two lines are parallel, we need to check if their slopes are equal.

The slope of the first line, y = -2x + 7, is -2.

The slope of the second line, 6x + 3y = 21, can be found by rearranging the equation to solve for y:

3y = -6x + 21, divided by 3

y = -2x + 7

The slope of the second line is also -2. Since the slopes are equal, the lines are parallel.

However, to determine if two lines are perpendicular, we need to check if the product of their slopes is -1. The slope of the first line is -2, and the slope of the second line is -2.

The product of their slopes is (-2)(-2) = 4, which is not equal to -1. Therefore, the lines are not perpendicular.

Answer:

The Click-O Pen Company produced 1.8 x 10^6 pencils each year for 4 years.

To find the total number of pencils produced during those 4 years, we need to multiply the number of pencils produced per year by the number of years:

Total number of pencils produced = (1.8 x 10^6) x 4

= 7.2 x 10^6

Therefore, the Click-O Pen Company produced a total of 7.2 million pencils during those 4 years.

Step-by-step explanation:

Start by identifying the number of pencils produced each year by the Click-O Pen Company. According to the problem statement, the company produced 1.8 x 106 pencils per year.

Next, determine how many years the company produced pencils for. In this case, we know that the company produced pencils for 4 years.

To calculate the total number of pencils produced during those 4 years, we need to multiply the number of pencils produced per year by the number of years. This gives us:

Total number of pencils = 1.8 x 106 pencils/year x 4 years

We can simplify this expression by multiplying 1.8 x 4 to get:

Total number of pencils = 7.2 x 106 pencils

Therefore, the Click-O Pen Company produced a total of 7.2 x 106 pencils during the 4-year period.

The new functions are:

(f + g)(x) = 3x - 4

(g - h)(x) = 6x - 4

(f o g)(x) = 2x - 4

(g o h)(x) = -8x - 1

And the value of (f-g)(3) = -2.

To find new functions, we can combine the given functions using arithmetic operations.

(f + g)(x) = f(x) + g(x) = (x - 1) + (2x - 3) = 3x - 4

(g - h)(x) = g(x) - h(x) = (2x - 3) - (1 - 4x) = 6x - 4

(f o g)(x) = f(g(x)) = f(2x - 3) = (2x - 3) - 1 = 2x - 4

(g o h)(x) = g(h(x)) = g(1 - 4x) = 2(1 - 4x) - 3 = -8x - 1

To find (f-g)(3), we need to evaluate the function (f - g) at x = 3:

(f - g)(3) = f(3) - g(3) = (3 - 1) - (2(3) - 3) = 1 - 3 = -2

You will earn R450 in interest ($1500 x 0.10 x 3 = $450). Simple interest is calculated by multiplying the principal by the interest rate and the number of years.

The interest earned on a fixed deposit of R1500 at 10% p.a simple interest for 3 years will be R450.

To calculate the interest earned, we need to use the simple interest formula:

where I is the interest earned, P is the principal amount, r is the interest rate and t is the time period.

P = R1500

r = 10%

t = 3 years

I = 1500 * 0.10 * 3

I = R450

The interest rate of 10% per annum is the same for each year, and the interest is calculated on the initial principal, not the accumulated interest from previous years. This is why the formula for simple interest is so simple - the same calculation is applied each year, so the amount of interest earned increases each year, but at a slower rate than with compound interest.

The total amount of interest earned over the 3 years is R450, which is calculated by multiplying the principal by the interest rate and the number of years.

These lines never intersect, there are no solutions to the equation.

In mathematics, a graph is a visual representation of a set of objects and the relationships between them. Graphs are widely used in many areas, including mathematics, computer science, engineering, social sciences, and more.

A graph consists of two main components: vertices (also known as nodes) and edges. The vertices represent the objects, and the edges represent the connections or relationships between them. The edges can be directed or undirected, meaning they can be one-way or two-way relationships.

There are many types of graphs, including:

Undirected graphs: Graphs in which edges have no direction.

Directed graphs: Graphs in which edges have a direction, often represented by arrows.

Weighted graphs: Graphs in which edges have weights or values, representing some kind of numerical data.

Bipartite graphs: Graphs in which the vertices can be divided into two distinct sets, with edges only connecting vertices in different sets.

Complete graphs: Graphs in which every vertex is connected to every other vertex by an edge.

Graphs are used to model and analyze various kinds of data, such as social networks, transportation systems, financial transactions, and more. They are also used in algorithms and data structures, such as shortest path algorithms and tree data structures. In addition, graphs are often visualized using software tools to help people better understand complex relationships and patterns in data.

With the help of using Pythagoras Theorem, we find out the value of C in this abc right angled triangle. A = 12units, B = 5 units and C = 13 units.

assuming that A and B are the lengths of the legs of a right angled  triangle and we need to find the length of the hypotenuse (c), we can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs. Using this theorem, we can write:

c² = a² + b²

Substituting the given values, we get:

c² = 12² + 5²

c² = 144 + 25

c² = 169

c = √169

c = 13

Therefore, the length of the hypotenuse (c) is 13 units. the Pythagorean theorem is a mathematical formula that relates to the sides of a right angled triangle. It states that in a right angled triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides (legs).

Given is that the senior class at high school A rented and filled 3 vans and 7 buses with 263 students. High school B rented 12 vans and 3 buses with 177 students. every van had the same number of students in it as did the buses.

Assume that there are {x} students in each van and {y} students in each bus. We can write the system of equations as -

3x + 7y = 263

12x + 3y = 177

3x + 7y = 263

3x = 263 - 7y

4 x 3x = 4(263 - 7y)

12x = 1052 - 28y

So -

1052 - 28y + 3y = 177

25y = 1052 - 177

25y = 875

y = 35                                           ... { 1 }

and

3x + 7 x 35 = 263

3x = 18

The surface area of a golf ball can be calculated using the formula for the surface area of a sphere:

Surface area = 4πr^2, where r is the radius of the ball.

We don't know the radius of the golf ball, but we do know its circumference, which is:

Circumference = 2πr

Therefore, we can rearrange the formula to solve for the radius:

r = Circumference / 2π = 13.408 cm / 2π ≈ 2.132 cm

Now we can calculate the surface area:

Surface area = 4π(2.132 cm)^2 ≈ 57.11 cm^2

Number of dimples per square centimeter ≈ Number of dimples / Surface area

For a golf ball with a circumference of 0.170 cm:

Number of dimples per square centimeter ≈ 336 / (4π(0.085 cm)^2) ≈ 233.8 dimples/cm^2

For a golf ball with a circumference of 1.468 cm:

Number of dimples per square centimeter ≈ 336 / (4π(0.734 cm)^2) ≈ 12.1 dimples/cm^2

The amount after 5 years with a simple interest of 5 % is A = $ 875

Simple interest is a method of calculating interest that ignores the impact of compounding. While interest frequently compounds throughout the course of a loan's set periods, simple interest does not. Simple interest is calculated by multiplying the principal amount by the interest rate, times the number of periods.

Simple Interest = ( Principal Amount x Rate x Time Period ) / 100

Given data ,

Let the amount in the bank after 5 years be A

Let the simple interest be represented as I

Now , the principal amount invested = $ 700

The rate of interest r = 5 %

The number of years n = 5 years

Simple Interest = ( Principal Amount x Rate x Time Period ) / 100

On simplifying , we get

Simple Interest I = ( 700 x 5 x 5 ) / 100

Simple Interest I = 25 x 7

Simple Interest I = $ 175

Now , the amount after 5 years = P + I = 700 + 175
