What is Reflection?

Reflection is a type of transformation that flips a shape along a line of reflection, also known as a mirror line, such that each point is at the same distance from the mirror line as its mirrored point. The line of reflection is the line that a figure is reflected over. If a point is on the line of reflection then the image is the same as the pre-image. Images are always congruent to pre-images

The reflection of point (x, y) across the x-axis is (x, -y). When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of the point (x, y) across the y-axis is (-x, y)

Given data ,

Let the coordinates for the dining be = D (x , y )

Let the coordinate of the point D (x , y ) be = D ( -4.5 , 4.5 )

Now ,

The coordinates for the flag pole is D'

where D' ( x₁ , y₁ ) is the reflection of  D (x , y ) across the y-axis

So , When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of the point (x, y) across the y-axis is (-x, y)

Therefore , D' ( x₁ , y₁ )  = D' ( 4.5 , 4.5 )

Now ,

The coordinates for the campfire is D'' ( x₂ , y₂ )

where D'' ( x₂ , y₂ ) is the reflection of D' ( x₁ , y₁ ) across the x-axis

So , When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is taken to be the additive inverse. The reflection of the point (x, y) across the x-axis is (x, -y)

Therefore , D'' ( x₂ , y₂ ) =  D'' ( 4.5 , -4.5 )

Hence , The coordinates of the campfire is D'' ( x₂ , y₂ ) = D'' ( 4.5 , -4.5 )

The system of two linear equations in two variables that we can solve by subtracting the equations and that results in a solution of (3, 1) is:-

x + y = 4

2x - 3y = 3

Let x + y be equation (1) and  2x - 3y = 3 be equation (2).

Multiplying (1) by 2, we get,

2x + 2y = 8 ...(3)

(3) - (2), we get,

(2x - 2x) + (2y - (-3y)) = 8 - 3

0 + 5y = 5

y = 5/5 = 1

y = 1

Putting y = 1 in (1), we get

x + 1 = 4

x = 4 - 1

Step-by-step explanation:

I assume you mean as second question "what is the volume of a cube with the surface area of 54 cm² ?".

first question :

volume is 8 cm³

the volume of a cube is side³.

8 cm³ = side³

side = cubic root(8) = 2 cm

add-on : the surface of a cube (6 sides) is 6 times the area of side² squares.

surface = 6 × 2² = 6 × 4 = 24 cm²

second question :

54 cm² = 6 × side²

9 = side²

side = sqrt(9) = 3 cm

and the volume would be

side³ = 3³ = 27 cm³

ANSWER :

Two ordered pairs (Solution) : (-4, -4) and (-3, -3)

Two ordered pairs (Not a solution) : (1, 1) and (2, 3)

EXPLANATION :

From the problem, we have :

Note that the boundary line is dashed or broken if the inequality symbol is < or >.

Otherwise, the boundary line is a solid line.

Graph the first inequality :

Change the symbol to "="

Solve for the x and y intercepts.

Test the inequality at the origin (0, 0)

The region will pass through the origin if it satisfy the inequality.

Therefore, the region will NOT pass through the origin.

Plot the points (0, 3) and (-1, 0).

Connect it with a solid line.

The region will NOT pass the origin.

Graph the second inequality :

Change the symbol to "="

Since y must be less than -2, the region is from y = -2 to the negative infinity.

Plot the point (0, -2) and draw a horizontal dashed line since the symbol is <.

That will be :

The solution to the inequality is the overlapping region.

Any point in the overlapping region is a solution.

Two ordered pairs solution are (-3, -3) and (-4, -4)

Two ordered pairs that are NOT a solution : (1, 1) and (2, 3)

A number line is a diagram of a graduated straight line used to represent real numbers in elementary mathematics. It is assumed that every point on a number line corresponds to a real number, and that every real number corresponds to a point. A number line is a visual representation of numbers on a straight line in mathematics. A number line's numbers are arranged in a sequential manner at equal intervals along its length. It is typically represented horizontally and can extend indefinitely in any direction. A number line is exactly what it sounds like—a horizontal, straight line with numbers spaced evenly apart along its length.

Answer:

Cone

100.6in^2

Step-by-step explanation:

Plato answer.

The approximate surface area of the shell is 75π square inches.

Find the area that its outer surfaces possess. Sum of all those surfaces' area is the surface area of the considered object. Right circular cone is the cone in which the line joining peak of the cone to the center of the base of the circle is perpendicular to the surface of its base.

We are given that;

Diameter= 5in

Height=10in

Now,

Substituting these values in the formula for surface area of a cone, we get:

Surface area of a cone = π(5)(5 + 10)

Simplifying, we get:

Surface area of a cone = 75π in²

Therefore, the surface area will be 75π square inches.

Given the number line, it appears that in every 1/2 of a number, there are 5 bars in it. And in every 5 bars, 4 bars were shaded.

Adding the number of shades, we get:

4 + 4 + 4 = 12

Adding the total number of bars, we get:

5 + 5 + 5 = 15

The total number of bars sums up to be 3/2 in the number line.

  c = 0

Step-by-step explanation:

You want the value of c such that point (c, 4) is on the line with slope 1 through point (-7, -3).

The point-slope equation of a line with slope m through point (h, k) is ...

  y -k = m(x -h)

The line with slope 1 through point (-7, -3) has equation ...

  y +3 = 1(x +7)

  y = x +4 . . . . . . . subtract 3 and simplify

The value of x when y=4 can be found using this equation.

  4 = x +4

  0 = x . . . . . . . subtract 4

The value of c is 0.

The simplest form of the given equation [9(-7t + 4t — 10) — 9t] is [-36t - 90].

If a fraction's top and bottom have only one other common factor, it is said to be in its simplest form.

In other words, the top and bottom cannot be divided further and remain whole numbers.

The simplest form is sometimes referred to as "lowest terms."

So, the simplest form of the equation:

9(-7t + 4t — 10) — 9t

Now, calculate to simplest terms as follows:

9(-7t + 4t — 10) — 9t

-63t + 36t - 90 - 9t

-63t + 27t - 90

-36t - 90

The sum of the interior angles of   a tringle is 180°.  The smaller tringle on the right adds up  to 180.

One angle is 90, that is the angle that has a small square. Another angle is 55 so the last angle needs to be 35 (90+ 55+35 = 180)

I think you are trying to answer #7 ?   I'll do that one

I see that you knew X =35°  

and you knew that b/c it's always 180° around the inside,  or interior , or minor angles of the RIGHT triangle (i'm making a big point out of the triangle being a "Right" one, b/c it matters for what we know about the triangle.)

so now you can add 10° to the 55° to get the next bigger RIGHT triangle.

65° is the upper angle so the ∠z = 25°

also you know [tex]y^{0}[/tex] b/c you know [tex]x^{0}[/tex] = 35°  and  

[tex]y^{0}[/tex]  +  [tex]x^{0}[/tex] = 180   ,  again
