The coordinates of B’ is given by D. A'(2, -5)

Since point A is at (2, 5), and you are reflecting it across the x-axis, you take a look at the y-coordinate.

<h3>What is the reflecting axis?</h3>

A reflection of a point, a line, or a figure in the X-axis involved reflecting the image over the x-axis to create a mirror image. In this case, the x-axis would be called the axis of reflection.

Since it is five above the x-axis, you go five below the x-axis, or just give the opposite of 5, which is -5.

So, A' is at (2, -5).

Answer: 56 large cars and 86 small cars.

Step-by-step explanation:

Let's call:

$l$ : the number of large cars.

$s$ : the number of small cars.

Then, you can set up the following system of equations:

$\left \{ {{l+s=142} \atop {5.50l+4.0s=652.50}} \right.$

You can use the Elimination Method:

- Multiply the first equation by -4.0

- Add both equations.

- Solve for l.

$\left \{ {{-4.0l-4.0s=-568} \atop {5.50l+4.0s=652.50}} \right.\\--------\\1.5l=84.5$

$l$ ≈ $56$

Substitute $l=56$ into one of the original equations and solve for <em>s:</em>

<em> </em> $56+s=142\\s=142-56\\s=86$

What is the formula of a circle in terms of its circumference <br> A=pi*r^2<br> C=2*pi*r

Alja [10]

"Formula of a circle" is too vague to be meaningful. Perhaps you meant, "Formula for the area of a circle in terms of its circumference."

The area of a circle in terms of its radius is A = πr^2. To put this formula to use, we have to know the radius of the circle. The circumference of a circle in terms of its radius is C = 2πr, so a formula for the radius is r = C / (2π).

Now let's find a formula for the area of a circle in terms of its circumference:

C C^2

A = πr^2 = π { ---------------- }^2 = ------------

2π 4π

or:

A = (C^2) / 4π

A man is 6 feet tall. To find the height of a tree, the shadow of the man and the shadow of the tree were measured. The length o

Sidana [21]

The answer is 16 ft because 6 ft tall over 4 feet 6 inches (4.5) is equal to x (tree's height) over 12 ft. You cross multiple and get 72 = 4.5x then you take 72 and divide by 4.5 to get the tree's height

$\frac{6}{4.5} = \frac{x}{12}$
