The formula of the image of a line is( l−p)/a = (m−q)/b = -2(ap+bq+c)/√a²+b²

What is the image of a line?

Typically, a little dash is used to identify a point's reflection, such as A'. This is said with a "prime." As a result, line AB's reflection is known as A'B'. The reflection is referred to as line AB's "image."

Here,

We have to determine the formula of the image of a line.

We concluded that

The mirror's "reflection" of the specified point P causes it to appear at an equal distance away on the opposite side of the line. To see this, move point P. According to tradition, the "image" of point P is the reflection of point P across the line, which is designated by the term P' (pronounced "P prime").

Hence, the formula of the image of a line is( l−p)/a = (m−q)/b = -2(ap+bq+c)/√a²+b²

The shape forms a pentagon. The value of y is  84°.

What is a polygon?

In geometry, a polygon is any closed curve made up of a series of line segments (sides) joined so that no two segments cross. Triangles (three sides), quadrilaterals (four sides), and pentagons are the simplest polygons (five sides).

The shape ABCDE forms a petagon.

The interior angle of a pentagon is 108°

The interior angle of a hexagon is 120°.

The ∠ABC is an angle of a regular hexagon, thus ∠ABC = 120°.

The ∠BCD is the angle of a regular hexagon, thus ∠BCD =120°.

The ∠BAE is an angle of a regular pentagon, thus ∠BAE=108°.

The ∠AED is an angle of a regular pentagon, thus ∠AED=108°.

The sum of all interior angle of a pentagon is 540°

Therefore,

∠ABC + ∠BCD + ∠BAE + ∠AED +∠EDC = 540°

120° + 120° + 108° + 108° + y = 540°

456° + y = 540°

y =  540° - 456°

y = 84°

Answer:

y= 3 2/4

Step-by-step explanation:

2 1/4 + 3 2/4 = 5 3/4

Answer: y= 7/2 = 3 1/2 = 3.5

Step-by-step explanation:

2 1/4 +y=5 3/4

Multiply both sides of the equation by 4.

2×4+1+4y=5×4+3

Multiply 2 and 4 to get 8.

8+1+4y=5×4+3

Add 8 and 1 to get 9.

9+4y=5×4+3

Multiply 5 and 4 to get 20.

9+4y=20+3

Add 20 and 3 to get 23.

9+4y=23

Subtract 9 from both sides.

4y=23−9

Subtract 9 from 23 to get 14.

4y=14

Divide both sides by 4.

y= 14/4

Reduce the fraction 14/4 to lowest terms by extracting and canceling out 2.

y= 7/2

The slope of the given expression is calculated using slope-intercept form. And the answer is 0.

How steep a line is or how much y climbs as x rises is determined by its slope. Slope compares changes to the y-axis, or the vertical axis, with changes to the x-axis, or the horizontal axis. The ratio of any two y values to any two x values can be used to calculate it.

By slope intercept, the standard equation is written as y=mx+b. Here, b is considered as the y-intercept, and m is considered as the slope. Then, the slope is calculated by comparing the given expression with this.

From the given expression, y = -6, we can tell the value of x is zero, the slope is also zero, and the y-intercept b is -6. Therefore, the required answer is 0.

An isosceles right triangle has a perimeter of 16 square centimeters since the hypotenuse is 8 length.

A boundary is a closed path that surrounds, delimits, or includes a two-dimensional shape or a one-dimensional length. The outermost part of a circle or an ellipse is called the perimeter. The perimeter calculation has numerous real-world applications. A shape's perimeter is the measurement of its edge's radius. Discover how to calculate the perimeter by adding together the lengths of the sides of various forms. The perimeter of any shape can be calculated by multiplying its side lengths. An object's perimeter is the region that surrounds it. A good illustration of this at your house is a closed-off garden. Its perimeter is the space encircling something. For a 50 by 50 foot yard, a 200 foot fence will be required.

given

AC (hypotenuse) = 8 cm. ,

AB^2+BC^2 = AC^2

x^2+x^2 = 8^2

2x^2 = 64

x^2= 64/2=32

x = 4.2^1/2 cm.

Perimeter = {8 +4.(2)^1/2+4.(2)^1/2}

= {8+8.(2)^1/2}

=8(1+2^1/2) cm.

Area =( base×altitude)/2= (4.2^1/2×4.2^1/2)/2 = 16sq.cm.

It is possible to construct a triangle whose sides are 18 cm 24 cm and 30 cm because the sum of two sides are greater than three sides.

In the given question, we have to check that it is possible to construct a triangle whose sides are 18 cm 24 cm and 30 cm.

The sum of the two sides must always be greater than the third side in order to determine whether or not the given sides may form a triangle.

To check this we firstly add the 18 and 24

18 + 24 > 30

42 > 30

Now we add 18 and 30

18 + 30 > 24

48 > 24

A mixed fraction is a fraction that is specified using the value of the quotient (the whole number part) and a fraction consisting of the remainder divided by the divisor.

The distance between the shelves of the cabinet = 12 1/12 inches

The height of the amplifier on a shelve of the cabinet on top of which Katherine stacks the CD player = 6 3/4 inches

The height of the CD player placed on top of the amplifier = 4 5/8 inches
