reflect over x axis transformation represents this rule (x, y) → (–x, y).

Make a coordinate plot using squared paper.

An illustration.

take the coordinate points (2,3) and (-3,-2)

They are reflected in the x-axis.

The results that you should get are as follows.

(2,-3) and (-3,2)

The y-coordinate is the opposite of the original position, while the x-coordinate is unchanged.

This can be described generally as (x, y) → (–x, y).

When a point is reflected across the X-axis, its X-coordinate stays constant. On the other hand, the Y-coordinate is altered to the opposite sign.

The point (x,y) is therefore reflected across the X-axis as (x,-y).It is known as a reflect over x axis transformation.

the first of a series of usually four downs in which a football team must net a 10-yard gain to retain possession of the ball.

If the team with the ball can pick up one yard or more on the third-down play, then they will be given a first down, which means they get to start all over with a new set of four downs. A team can continue moving the football down the field as long as they continue to pick up first downs.

we have been given that -

Here are the integers that are represented by the scenario.

Martha's claim that the 25% of the learners are girls, is correct.

In this question,

There are 900 boys and 300 girls at Eqinisweni secondary school.

Martha claims that 25% of the learners are girls.

We need to verify her claim by means of calculations.

Based on the given conditions, we formulate:

300 / (900 + 300)

We simplify above expression.

= 300 / 1200

= 1/4               ..................(Cross out the common factor)

Now multiply a number 25 to both the numerator and the denominator:

r = \frac{GM}{v^{2} } formulas have been correctly rearranged to solve for radius.

What is circular motion ?

The problem is asking to find the radius of the orbit of a satellite around a planet, given the orbital speed of the satellite.

For a satellite in orbit around a planet, the gravitational force provides the required centripetal force to keep it in circular motion, therefore we can write:

[tex]\frac{GMm}{r^{2} } = m\frac{v^{2} }{r}[/tex]

where

G is the gravitational constant

M is the mass of the planet

m is the mass of the satellite

r is the radius of the orbit

v is the speed of the satellite

Re-arranging the equation, we find

[tex]\frac{GM}{r} = v^{2}[/tex]

[tex]r = \frac{GM}{v^{2} }[/tex]

The volume of the rectangular prism is 243 cm³

given that

The top face of the cube has an area of 9 cm²

since All the faces of the cube are squares

therefore The top face is a square

∵ Area of any square = L² , where L is the length of the side of

 the square

∵ Area of the top face is 9 cm²

∴ L² = 9 ⇒ take √ for both sides

∴ L = 3 cm

∵ The volume of any cube = L³

∵ L = 3 cm

∴ The volume of the cube = (3)³ = 27 cm³

- We will use 9 cubes to make a rectangle prism

∴ The volume of the rectangle prism is equal to the volume of

 the 9 cubes

∴ The volume of the prism = 9 × volume of a cube

∵ The volume of the cube is 27 cm³

∴ The volume of the prism = 9 × 27 = 243 cm³

* The volume of the rectangular prism is 243 cm³

The transformation, the coordinates of point B' become (1, 15).

The transformation rule (x, y) → (x + 4, 3y) involves shifting the x-coordinate by 4 units to the right and stretching the y-coordinate by a factor of 3. To find the coordinates of B' after applying this rule, we take the coordinates of point B(-3, 5):

x-coordinate of B' = x-coordinate of B + 4 = -3 + 4 = 1.

y-coordinate of B' = y-coordinate of B * 3 = 5 * 3 = 15.

Therefore, after the transformation, the coordinates of point B' become (1, 15). This means that B' is located 4 units to the right of B along the x-axis and its y-coordinate is three times that of B. The transformation has shifted and stretched the original triangle, resulting in a new position for point B'.

The equation of the lines in slope intercept form and standard form is y = -2x + 10 and 2y+3x = 10

The equation of a line in point slope form is y = mx + b.

Given the equation below:

y-7 =-5/2(x+4)

2(y-7) = -5(x+4)

2y-14 = -4x - 20

2y = -4x-20+40

2y = -4x + 20

y = -2x + 10

For the equation;

y = -3/2 x + 5

Multiply through by 2

Notice that the variable is squared, this means that the sign does not matter, the outcome of:

-4x^2 will always be negative. So in both ends (when x tends to infinity and negative infinity), we will have the same end behavior.

When we take that limit, -4x^2 will just tend to negative infinity, then in both cases, the function tends to negative infinity.
