The new coordinates of the point in the transformed shape would be (-1/2x, -1/2y).

A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.

A scale factor of -1/2 around the center point (0,0) would reflect the shape across the origin and also shrink it by a factor of 1/2.

The transformation can be represented by the matrix:

[-1/2 0]

[ 0 -1/2]

This matrix would be applied to the coordinates of each point in the shape to obtain the new coordinates of the transformed shape.

So, if a point in the shape had coordinates (x, y), the new coordinates of the point in the transformed shape would be (-1/2x, -1/2y).

In conclusion, it can be argued that Abby Sunderland was too young to sail solo. Despite her ambitious and determined nature, her lack of experience and maturity put her at a significant risk during her solo sailing journey. The fact that she had to be rescued twice during her attempt highlights the dangers of attempting such a feat at such a young age. While it is admirable to have the courage to pursue one's dreams, it is important to consider the potential consequences and weigh them against the potential benefits. In this case, it can be argued that the risks far outweighed the potential rewards.

The equation of the perpendicular line is y = -7/2(x + 5) + 2

From the question, we have the following parameters that can be used in our computation:

y=2/7x-8

Also, from the question;

We have the following points

Point = (-4, 2) i.e.  (x, y) = (-4, 2)

The equation of a line can be represented as

y = mx + c

Where

Slope = m

By comparing the equations, we have the following

m = 2/7

This means that the slope is 2/7

The slopes of perpendicular lines are opposite reciprocals

This means that the slope of the other line is -7/2

The equation of the line is then calculated as

y = m(x - x₁) +y₁

Where

m = -7/2

(x₁, y₁) = (-4, 2)

So, we have

y = -7/2(x + 5) + 2

Hence, the line has an equation of y = -7/2(x + 5) + 2

To  find the center of dilation,We'll fix our compass to a distance that is closer to the overall distance but still greater than halfway between vertex L and point C. Start with the compass's point on vertex L while maintaining the same distance, and then draw a curve that intersects the line connecting L and C.

Centre of dilation  of an image in mathematics refers to a change that results in an image with the same shape but a different size, either larger or smaller. A dilation can only be built with two bits of information.

An operation that moves, flips, or otherwise alters a figure to produce a new figure is called a transformation. Rigid transformations maintain size, whereas non-rigid transformations do not. A dilatation enlarges or reduces a figure while maintaining its original shape. To put it another way, the dilatation resembles the original. Every dilatation has a scale factor and a centre. The scale factor indicates how much the figure stretches or contracts, and the centre serves as the point of reference for the dilation (much like the vanishing point in a perspective drawing). A scale factor is usually identified by a label and is never zero. Additionally, the dilatation would be if the original figure were labelled, for example.

The point from which the image is dilated is known as the centre of dilatation (or point of dilation).

Answer:

Step-by-step explanation:

I will assume you want the y-axis intercepts

arrange each equation into the form  y = mx + b  <==b  is  y-axis intercept

2x+y =1

y = -2x+1    <====  y axis intercept = 1

x -2y = 8

2y = x-8

y = 1/2x -4       <====  - 4 is the y axis intercept

Another way to find the y-axis intercept is to realize this occurs when x = 0

  put x = 0 into the equations to find the intercept value

2x+y =1

2(0) + y = 1

y =1    <=====intercept

x-2y = 8

0 - 2y = 8

y = -4   <=====intercept

To find the where the two lines intersect, equate them

-2x+1 = 1/2x-4

5 = 2.5x

x = 2    then y = -2x+1 = -3      point of intersection (2,-3)

Rose gets 12 refills by a coffee shop.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

A coffee shop sells a mug for $8.95. Each refill costs $1.50.

And, Last month Rose spent $26.75 on a mug and refills.

Let number of refills she get = x

So, We can formulate;

⇒ $8.95 + $1.50x = $26.75

⇒ 8.95 + 1.50x = 26.75

⇒ 1.50x = 26.75 - 8.95

⇒ 1.50x = 17.80

⇒ x = 17.8 / 1.5

⇒ x = 12

Step-by-step explanation:

The linear equation [ ( 2x PLUS y ) EQUALS 10 ] has only one solution.

A linear equation is an algebraic equation having the form y=mx+b, involving only a constant and a first-order (linear) term, where b is the y-intercept and m is the slope. Occasionally, the above is called a 'linear equation of two variables,' where x and y are the variables.

Now solve the given linear equation which is:

[ ( 2x + y ) = 10  ]

Now solve this equation in order to determine the number of solutions it has,

( 2x + y ) = 10

( 2x + (10 - 2x)) = 10

( 2x + 10 - 2x) = 10

( 2x + 10 - 2x) = 10

(10) = (10)

Since 10 = 10 is correct, therefore, the equation  ( 2x + y ) = 10 has only one solution.

The maximum price per egg that the supermarket may charge is $0.245 per egg, which is the difference between the pricing per egg for the 2 distinct cartons.

The answer to the query is

The following details are available to us:

We'll first calculate the cost per egg for each of the two different-sized cartons in order to determine the cost per egg that lies between the two costs.

We are aware that the cost of one product is determined by dividing the total cost by the quantity of products.

The price of an egg between 0.24 as well as 0.25 must now be determined.

Note that there is a 0.01 difference between the two fees.

To precisely determine the middle charge, we will split it by two:

0.01/2 = 0.005

This can be added to $0.24 or subtracted from $0.25.

$0.24 + $0.005 = $0.245

So, $0.245 is the maximum price the supermarket can charge per egg.

To multiply two mixed numbers, you can convert them to improper fractions and then multiply the numerators and denominators separately.

2 1/5 can be written as (2 x 5 + 1) / 5 = 11/5

2 2/3 can be written as (2 x 3 + 2) / 3 = 8/3

So the product of 2 1/5 x 2 2/3 is (11/5) * (8/3) = 88/15 which is equivalent to 5 8/15 or 5.533 repeating (if you want to express it as decimal)

You can simplify 88/15 by dividing both numerator and denominator by the greatest common divisor (GCD) which is 1 in this case, so the final result is 88/15.

The distance between the line and the point is 8 units.

When two parallel lines intersect, a two-dimensional coordinate plane called the cartesian plane is created. The horizontal line is the X-axis, while the vertical line is the Y-axis. If the sign of x is positive, the coordinate point (x, y) in the Cartesian plane indicates that the point is on the right of the origin; otherwise, it indicates that the position is on the left of the origin.

Given a line L,

and the equation of a line is y = 1

actual equation of line is ax + by +c = 0

equation of line is 0x + y - 1 = 0

here a = 0, b = 1 and c = -1

and point T(-1, -7)

distance between line and the point is d = [tex]\frac{|ax_1 + by_1 + c|}{\sqrt{a^2 + b^2} }[/tex]

x₁ = -1, y₁ = -7

|ax₁ + by₁ + c| = |0(-1) + 1(-7)  +(-1)|

|ax₁ + by₁ + c| = 8

√(a² + b²) = √(0² + (1)²) = 1

The number of cubic yards of each component needed are 3.99 cubic yards of cement, 7.97 cubic yards of sand  and 15.94 cubic yards of gravel

Ratio is used to compare two or more quantities. It is used to indicate how big or small a quantity is when compared to another

Since a total of 18.6 cu yd of concrete is required and the total amount of these components must be 1½ times the volume of concrete needed. We can say:

total amount of these components = 1½ × 18.6 cu yd = 27.9 cu yd

Also, since the ratio of cement to sand to gravel for this application is 1:2:4. We have:

Total share = 1 + 2 + 4 = 7

cement = 1/7  × 27.9 =  3.99 cubic yards

sand  = 2/7  × 27.9 =  7.97 cubic yards

gravel = 4/7  × 27.9 =  15.94 cubic yards
