The definition of a reflection of rectangle ABCD is option D:

"Every point X on ABCD is mapped to a new point X' such that one coordinate of X' is the same as in X, and the other coordinate of X' is the opposite of the other coordinate in X".

When a reflection occurs, each point on the original shape is mapped to a new location on the reflected shape.

Option A states that every point X on ABCD is mapped to a new point X' such that each length from X to X' is the same. This definition does not capture the essence of a reflection because it doesn't consider the relationship between the original shape and its reflection.

Option B states that every point X on ABCD is mapped to a new point X' such that the distance from X to the line of reflection is the same as the distance from X' to the line of reflection.

Option C states that every point X on ABCD is mapped to a new point X' such that the coordinates of X' are opposites of the coordinates of X.

Option D correctly captures the nature of a reflection. This states that each point X on ABCD is mapped to a new point X' where one coordinate of X' is the same as in X, and the other coordinate of X' is the opposite of the other coordinate in X.

Therefore, option D is the valid definition of a reflection of rectangle ABCD.

Answer:

cityQ

Step-by-step explanation:

City Q is located at the sea level

The statement that should be true is

City P is above sea level and City Q is below sea level.

The word "number line" in mathematics refers to a straight line where a number should be positioned at similar intervals or segments along with its length.

Given:

The point 0 on the number line represents sea level.

As, It should be presented in a horizontal style and be infinitely in any direction.

As a result, option c should be the statement that is true. City Q is below sea level, but City P is above it.

Answer:

y = -2x + 5

Step-by-step explanation:

Parallel lines have the same slope, so the line's slope would be -2.

Because we have a coordinate point and the slope of the line, we can figure out the equation by using the point slope formula:

( y - y1 ) = m( x - x1 )

( y - ( - 3 ) ) = -2 ( x - 4 )

y + 3 = -2x + 8

y = -2x + 5

The equation of the line is y = -2x + 5

Answer:

Solution: (-4,5)

Step-by-step explanation:

x=16-4y

3x+4y=8

-----

The 1st equation tells you x = 16-4y

---

Substitute that into the 2nd equation

and solve for "y":

3(16-4y)+4y = 8

48 - 12y + 4y = 8

-8y = -40

---

y = 5

---

Solve for "x"

x = 16-4y

x = 16-4*5

x = 16-20

x = -4

The given system of equations has (-4, 5) as its solution.

We have the following system of equations -

x = 16 - 4y

3x + 4y = 8

Now, we can write -

3x + 4y = 8

3(16 - 4y) + 4y = 8

48 - 12y + 4y = 8

40 = 8y

y = 5

Then, we can write -

x = 16 - 20

x = - 4

Therefore, the given system of equations has (-4, 5) as its solution.

The answer is -93/5.

Answer:

D. The samples are independent because there is not a natural pairing between the two samples

explanation:

Independent samples do not affect each other as each group is selected randomly. They are common in statistical analysis, example: when there is a control group and an experimental group and the subjects for each group are different. In the above example, the samples do not depend on each other. There are 90 randomly selected married men in one group and 90 randomly selected married women in the other. The subjects are different in the two groups and so they do not affect each other. This is unlike dependent/paired samples where for example same subjects are used before and after a medication and therefore each group affects the other.

Answer:

slope = 71.3  and a point (0, 7005.4)

Step-by-step explanation:

the slope in an equation of the form y = mx+b, m is the slope so multiply 71.3 through the brackets and then add 18 to both sides and that is the equation in y=mx+b format and 71.3 is the slope and b os the y-intercept which turns out b=7005.4 and since its a y-intercept x = 0

Answer:

The slope is 71.3 and the point on the line is (h, k):  (-98, 18)

Step-by-step explanation:

y - 18 = 71.3(x +98) is to be solved for the slope and a point on the line represented by this equation.

Refer to the point-slope formula   y - k = m(x - h), where (h, k) is a point on the ine and m is the slope of the line.

Comparing y - 18 = 71.3(x +98) to

                   y - k = m(x - h),

we readily see that k = 18, h = -98 and m = 71.3

The slope is 71.3 and the point on the line is (h, k):  (-98, 18)

Answer:

there are 18 girls

Step-by-step explanation:

for every 2 boys there are 3 girls

so then you can say 2/5 of the class are boys and 3/5 are girls

and you have to calculate 3/5 of 30 so you have to divide 5 and then multiply by 3 so 30 divided by 5 is 6 the n multiply 6 by 3 and the answer is 18.

Answer:

Step-by-step explanation:

In 3.5 hours, a total of 1950 gallons of water will be filled in swimming pool.

The general form of a linear function is given as follows -

y = kx

or

y = kx + c

Given is a swimming pool that holds 10,000 gallons of water is being filled at a rate of 600 gallons per hour. The function h(x)=600x represents the amount of water in the pool after [x] hours.

The linear function that represents the amount of water in the pool after [x] hours is given by -

h[x] = 600x

Now, for x = 3.5, the amount of water in the pool will be -

h[3.25] = 600 x 3.25 = 1950 gallons of water.

Therefore, in 3.5 hours, a total of 1950 gallons of water will be filled in swimming pool.

Answer: IF YOU ARE ON KHAN ACADEMY THE ANSWER IS NOT -1

THE CORRECT ANSWER ON KHAN IS -9/4

For equation 3 + 2y = √(-y) the extraneous solution does Lea obtain is y = (-13 + √97) / 8 or y = (-13 - √97) / 8

A quadratic equation is a second-order polynomial equation in a single variable x , ax²+bx+c=0. with a ≠ 0 .

When Lea squares both sides of the equation 3 + 2y = √(-y), she gets:

(3 + 2y)² = (-y)

Expanding the left side, we get:

9 + 12y + 4y² = -y

Bringing all the terms to one side, we get a quadratic equation:

4y² + 13y + 9 = 0

We can solve this quadratic equation using the quadratic formula:

y = (-b ± √(b² - 4ac)) / 2a

Substituting the coefficients a = 4, b = 13, and c = 9, we get:

y = (-13 ± √(13² - 4(4)(9))) / 2(4)

y = (-13 ± √97) / 8

So the solutions are:

y = (-13 + √97) / 8 or y = (-13 - √97) / 8

Hence, the extraneous solution does Lea obtain is y = (-13 + √97) / 8 or y = (-13 - √97) / 8
