this is geometry witch theorem or postulate proves these two triangles are similar

Answer:

When point A with coordinates (0, -1) is reflected across the x-axis and mapped onto point A', the coordinates of A' will be (0, 1).

i.e A'(0, 1) is the image of point A after a reflection.

Hence, point A is reflected across the x-axis.

Step-by-step explanation:

When we reflect a point A across the x-axis, the value of 'y' gets negated, but the value of 'x' remains unchanged.

In other words, when point P with coordinates (x, y) is reflected across the x-axis and mapped onto point P', the coordinates of P' will be (x, -y).

Thus, the rule is:

P(x, y) → P'(x, -y)

Thus, when point A with coordinates (0, -1) is reflected across the x-axis and mapped onto point A', the coordinates of A' will be (0, 1).

i.e A'(0, 1) is the image of point A after a reflection.

Hence, point A is reflected across the x-axis.

The term "not real" or "non-real" refers to imaginary and unreal numbers. The number line cannot display non-real numbers. A "actual" and practical idea, infinity. Infinity, on the other hand, is not a number on the real number line since it is not a part of the mathematically defined set of "real numbers." When measuring continuously fluctuating quantities like size and time, real numbers are utilized.

The option D shows a function has a domain of all real numbers.

The domain of a function is the set of input values for which the function is real and defined. In the other words, when you define the domain, you are indicating for which values x the function is real and defined.

     [tex]\left(x+2\right)^{^{\frac{1}{4}}\:}=\sqrt[4]{x+2}[/tex]

      Therefore, the function domain is x  [tex]\geq[/tex]-2.

        [tex]-x^{\frac{1}{2}}^{\:}+5=-\sqrt{x} +5[/tex]

        x  [tex]\geq[/tex] 0

      Therefore, the function domain is x  [tex]\geq[/tex] 0.

        [tex]-2\left(3x\right)^{\frac{1}{6}}=-2*\sqrt[6]{3x}[/tex]

          3x  [tex]\geq[/tex] 0

      Therefore, the function domain is x  [tex]\geq[/tex] 0.

Karen performed a transformation of (C) counterclockwise rotation of 90 degrees about origin

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

If a point A(x, y) is rotated 90° counterclockwise about the origin, the new point is at A'(-y, x).

Parallelogram ABCD has vertices at A(-4,-1) , B (-7,-6) , C (-14, -6) , D(-11, -1), if it is rotated 90° counterclockwise about the origin, the new point would be at A'(1.-4) , B'(6.-7),  C'(6.-14) , D'(1.-11)

The function shown in the graph is y = x+ 4.

The correct option is A.

The slope or gradient of a line in mathematics is a numerical representation of the steepness and direction of the line.

If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,

then the equation of line is

y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)

To find the slope;

m =  (y₂- y₁) / (x₂ - x₁)

To find the equation of the line that passes through the points (-4, 0) and (0, 4), we can use the point-slope form of the equation of a line as described in the definition.

First, let's find the slope of the line. We can use the formula:

m = (y2 - y1) / (x2 - x1)

where (x1, y1) = (-4, 0) and (x2, y2) = (0, 4):

m = (4 - 0) / (0 - (-4)) = 4 / 4 = 1

So the slope of the line is 1.

Next, let's choose one of the given points, say (-4, 0), and substitute its coordinates and the slope into the point-slope form:

y - 0 = 1(x - (-4))

Simplifying this equation, we get:

y = x + 4

So the equation of the line that passes through the points (-4, 0) and (0, 4) is y = x + 4.

the speed is 20 m/s

Step-by-step explanation:

The computation of the speed is as follows

As we know that

Speed = Distance ÷ time

where,

Distance is 420 meters

And, the time is 21 seconds

So, the speed is

= 420 ÷ 21

= 20 m/s

hence, the speed is 20 m/s

We simply applied the above formula so that the correct value could come

The empire state building is taller than a chair seat by three orders of magnitude.

Orders of magnitude refer to the classification based on the sizes of two objects against each other.

Orders of magnitude range in the power of 10 or 10ⁿ.

Orders of Magnitude:

10x = 1 order of magnitude

100x = 2nd order of magnitude

1000x = 3rd order of magnitude

Empire State Building = 1,500 feet

Chair seat = 1.5 feet

Order of magnitude = 1,000x (1,500/1.5)

Thus, the Empire State Building is about a thousand times taller than a chair seat or three orders of magnitude.

Ravi présent âge 15 because présent would be 20:15 and then it would turn into 25:20

Answer:

15 years old

Step-by-step explanation:

Given the ratio of their ages = 4 : 3 = 4x : 3x ( x is a multiplier )

Then in 5 years the ratio of their ages is 4x + 5 : 3x + 5 = 5 : 4, that is

[tex]\frac{4x+5}{3x+5}[/tex] = [tex]\frac{5}{4}[/tex] ( cross- multiply )

4(4x + 5) = 5(3x + 5) ← distribute both sides

16x + 20 = 15x + 25 ( subtract 15x from both sides )

x + 20 = 25 ( subtract 20 from both sides )

x = 5

Thus

Ravi's age is 3x = 3 × 5 = 15

The graph of a system of inequalities that represents this scenario will be A. On a coordinate plane, 2 straight lines are shown. The first solid line is horizontal to the y-axis at y = negative 1. Everything above the line is shaded. The second dashed line has a positive slope and goes through (0, negative 4) and (2, negative 2). Everything below and to the right of the line is shaded.

In Algebra, an inequality is a mathematical statement that uses the inequality symbol to illustrate the relationship between two expressions.

On one day, x, the outside temperature never fell below 1°. A automobile was always at least 4 degrees warmer inside than it was outdoors.

y -1 is the inequality for the first line.

Y > x + 4 is the inequality that represents the second line.

The darkened area is therefore above the first line, which is a solid horizontal line.

The shaded area lies above and to the left of the second line, which has a broken line and a positive slope.

Therefore, the correct option is A.
