What is 2x+21? Please it's due in about 15 minutes!!!

Answers

Answer 1

Answer:

The value of x is 21

Step-by-step explanation:

2x+21 is a linear equation with one unknown, x. To solve for x, we can use the following steps:

1. Subtract 21 from both sides of the equation. This will isolate x on the left-hand side of the equation.

```

2x+21 - 21 = x

```

2. Divide both sides of the equation by 2. This will divide both sides of the equation by 2, which will cancel out the 2 on the left-hand side of the equation, leaving x by itself.

```

x = (2x+21)/2

```

3. Simplify the right-hand side of the equation.

```

x = x/2 + 21/2

```

4. Combine like terms on the right-hand side of the equation.

```

x = (1/2)x + 21/2

```

5. Subtract (1/2)x from both sides of the equation. This will isolate x on the left-hand side of the equation.

```

x - (1/2)x = (1/2)x + 21/2 - (1/2)x

```

6. Simplify the right-hand side of the equation.

```

(1/2)x = 21/2

```

7. Multiply both sides of the equation by 2. This will multiply both sides of the equation by 2, which will cancel out the (1/2) on the left-hand side of the equation, leaving x by itself.

```

2*(1/2)x = 21/2 * 2

```

8. Simplify the right-hand side of the equation.

```

x = 21

```

Therefore, the value of x is 21.

Answer 2

I only know the first one well. I don't want to answer the others and maybe give false info.

Step-by-step explanation:

Egyptians were very well known to be very interested in Spirits and Gods.

Their whole dynasty was built on the dawn of their Gods. There were many, like the Greek and Roman Gods. One of the sun, one of the underworld....etc..

The pharaohs believed themselves to be god. (Due to their immense power)

Egyptians believed that after death there was an Afterlife. In that afterlife, there was games, other people (spirits), homes (graves). This might sound weird but in the graves especially of Pharaohs they placed beds, tables, chairs, games..etc..

what value of x makes this equation true -(x+3)=2(x-3)

A. 0
B. 1
C. 2
D. 3

Answers

Answer:

To solve the equation -(x + 3) = 2(x - 3) for x, we can follow these steps:

Step 1: Distribute the negative sign on the left side of the equation:

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

=> -x - 3 = 2(x - 3) (using the distributive property)

Step 2: Expand the right side of the equation:

-x - 3 = 2x - 6

Step 3: Add x to both sides of the equation to isolate the x term on one side:

-x + x - 3 = 2x + x - 6

=> -3 = 3x - 6

Step 4: Add 6 to both sides of the equation:

-3 + 6 = 3x - 6 + 6

=> 3 = 3x

Step 5: Divide both sides of the equation by 3 to solve for x:

3/3 = 3x/3

=> 1 = x

So, the correct value of x that makes the equation true is B. 1.

PLEASE MARK BRAILYISTT :D

Answer:

B, one

Step-by-step explanation:

In order to solve this, you can solve the equation. First, you can use the distributive property to get -x-3=2x-6. If you make the variables on one side and the constants on the other, you will get -3x-3=-6. This can further simplify to -3x=-6. Divide both sides by -3 to get that x=1. Then, the correct answer is B.

Which is the equation for a sphere with the center (8,-6,6) and radius 6?

Answers

Answer:

(x - 8)² + (y+6)² + (z-6)²= 36

Step-by-step explanation:

To find the equation for a sphere with the center (8,-6,6) and radius 6, we will follow the steps below;

first write down the standard equation of a sphere:

(x - h)² + (y-k)² + (z-l)²= R²

where h, k and l are the center  and  R is the radius

From the question given, h = 8, k =-6  l=6  and R=6

we can now substitute the values into the formula

(x - h)² + (y-k)² + (z-l)²= R²

(x - 8)² + (y+6)² + (z-6)²= 6²

(x - 8)² + (y+6)² + (z-6)²= 36

Therefore, the equation for a sphere with the center (8,-6,6) and radius 6  is

(x - 8)² + (y+6)² + (z-6)²= 36

What is Coordinates?

A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.

Given that;

Triangle LMN is drawn with vertices at L(−4, −1), M(0, −1), N(−4, −3).

Now, We know that;

The rule of rotation 90° clockwise is,

⇒ (x, y) = (y, - x)

Thus, We get;

L = (- 4, - 1)

L'= (- 1,  4)

M = (0, - 1)

M' = (- 1, 0)

N = (- 4, - 3)

N' = (- 3, 4)

Hence, The image vertices of L′M′N′ if the preimage is rotated 90° clockwise are,

⇒ L′(- 1, 4), M′(-1, 0), N′(- 3, 4)

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?

Answers

To determine whether Keira's statement is correct, we need to analyze the information provided.

According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.

If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.

However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.

Therefore, without additional information, we cannot determine the accuracy of Keira's statement.
in order to know if Keira has two tickets left, we need to know the first number of tickets without that number there is no way to find the remainder

Answer:

A

Step-by-step explanation:

We can solve for H by isolating it on one side of the equation, as follows:

J/H - I/H = G

Taking H as the common denominator:

(J - I)/H = G

Multiplying both sides by H:

J - I = GH

Adding I to both sides:

J = GH + I

Dividing both sides by G:

H = (J - I)/G

So the answer is

(A)

H = (J - I)/G.

Answer:   A

Step-by-step explanation:

\(\frac{J}{H} = G + \frac{I}{H}\)                >Since you are solving for H bring I/H to the other side

                                   by subtracting I/H from both sides

\(\frac{J}{H}- \frac{I}{H} = G\)               >There is a common denominator so you can

                                   combine the fractions

\(\frac{J-I}{H} = G\)                   >Multiply both sides by H or cross multiply whichever

                                  way your mind things about how to get H on top

\(J-I = G(H)\)           >Divide both sides by G

\(\frac{J-I}{G} = H\)                   >Answer is A

Pentagon HIJKL is translated right 2 units and 9 units down to produce H'I'J'K'L'. Then, H'I'J'K'L' is reflected across the y-axis to produce H''I''J''K''L''.

Answers

To visualize the transformation, you can draw the Pentagon HIJKL on a coordinate plane, where each vertex corresponds to a point in the plane. Let's say the coordinates of the vertices are:

- H = (x1, y1)
- I = (x2, y2)
- J = (x3, y3)
- K = (x4, y4)
- L = (x5, y5)

Then, to translate the pentagon right 2 units and down 9 units, you can add 2 to each x-coordinate and subtract 9 from each y-coordinate to get the new coordinates:

- H' = (x1 + 2, y1 - 9)
- I' = (x2 + 2, y2 - 9)
- J' = (x3 + 2, y3 - 9)
- K' = (x4 + 2, y4 - 9)
- L' = (x5 + 2, y5 - 9)

Next, to reflect H'I'J'K'L' across the y-axis, you can negate the x-coordinates to get the new coordinates:

- H'' = (-x1 - 2, y1 - 9)
- I'' = (-x2 - 2, y2 - 9)
- J'' = (-x3 - 2, y3 - 9)
- K'' = (-x4 - 2, y4 - 9)
- L'' = (-x5 - 2, y5 - 9)

These new coordinates represent the vertices of the transformed pentagon H''I''J''K''L''.

Note that the order of the transformations matters. If you had reflected the original pentagon across the y-axis first, and then translated it, you would have gotten a different result.
New coordinates are H”” I”” J” K” L’
