What is the solution set of {x | x 5}?

1. the empty set
2. all real numbers
3. the numbers between -5 and 5
4. all numbers less than -5 and greater than 5

Answers

Answer 1

Answer:

3. the numbers between -5 and 5

Step-by-step explanation:

Let set A= [tex]\{x| x>-5\}[/tex] and set [tex]B=\{x | x<5\}[/tex].

The solution set of A and B is the solution set of A∩B

The solution set of A is all the real number x which is greater than -5.

The solution set of B is all the real number x which is less than 5.

Therefore, the solution set of A∩B is all the real numbers between -5 and 5.

Hence, option (3) is correct.

Use elimination to solve the system.

2x + 3y = 1
5x – 4y = 14

help would be appreciated :)

Answers

Answer:

x = 2, y = -1

Step-by-step explanation:

To solve this with elimination, we first multiply the first equation by -2.5

Our new equations are:

-5x - 7.5y = -2.5

5x – 4y = 14

After adding these two equations together, the x cancels out and we have:

-11.5y = 11.5

Divide both sides by -11.5

y = -1

Plugging this value into y in one of the equations we have:

2x + 3y = 1

2x + 3(-1) = 1

2x - 3 = 1

Add 3 to both sides

2x = 4

Divide both sides by 2

x = 2

1.Encuentra la ecuación de la circunferencia que tiene como ecuación ordinaria (x-4)² + (y+5)²= 25 2- encuentra la ecuación general de la circunferencia que tiene como ecuación ordinaria (x+1)² + (y+9)²=49

Answers

Responder:

1) x² + y²-8x + 10y + 16 = 0

2) x² + y² + x + 18y + 33 = 0

Explicación paso a paso:

A partir de la pregunta, debemos expresar la ecuación en la forma estándar de un círculo expresado como;

x² + y² + 2gx + 2fy + c = 0 donde;

(-g, -f) es el centro.

1) Para la ecuación (x-4) ² + (y + 5) ² = 25

Expande el paréntesis;

(x-4) ² + (y + 5) ² = 25

x²-8x + 16 + y² + 10x + 25 = 25

x²-8x + 16 + y² + 10y + 25-25 = 0

Recopile términos similares;

x² + y²-8x + 10y + 16 + 0 = 0

x² + y²-8x + 10y + 16 = 0

Por lo tanto, la ecuación requerida es x² + y²-8x + 10y + 16 = 0

2) Para la expresión (x + 1) ² + (y + 9) ² = 49

x² + x + 1 + y² + 18y + 81 = 49

x² + x + 1 + y² + 18y + 81-49 = 0

Recopile términos similares;

x² + y² + x + 18y + 82-49 = 0

x² + y² + x + 18y + 33 = 0

Por tanto, la ecuación requerida es x² + y² + x + 18y + 33 = 0

Answer:

x = 34°

Step-by-step explanation:

Use property of exterior angles:

Exterior angle = sum of non-adjacent interior angles

Here we have:

∠D + ∠E = ∠EFG∠EFG = ∠EFH + ∠HFG = 90° + 42° = 132°

So the equation is:

2x + 64° = 132°2x = 132° - 64°2x = 68°x = 68°/2x = 34°

If you think it is not 34°, then your question must be asking to find something else (e.g. angle D, which is 68°)

The distance between two stars is 9.0 x 10 to the power of -3 light years. A light year is equal to
5.88 x 10 to the power of 12 miles. What is the distance, in miles, between the two stars

Answers

Answer:

The distance between the two stars in miles is 5.292 * 10^10 miles

Step-by-step explanation:

Here, we want to make a conversion from light year to miles

To make this conversion, we simply are going to multiply the light year by the miles

Mathematically, we have this as;

9 * 10^-3 * 5.88 * 10^12

= 52.92 * 10^9

= 5.292 * 10^10 miles

x/5 - g = a for x

how can i find x?

Answers

Answer:

X = 5a+5g

Step-by-step explanation:

Adding g on both sides gives:

X/5 = a+g

Now dividing 5 on both sides gives us the value of x which is:

X = 5(a+g)

Hence X=5(a+g) or X=5a+5g( multiplying by 5 gives us 5a and 5g)

2. Find the distance between the points K(-2, 3) and L(4,7)

Answers

Answer:

7.21 (7.211103 exact)

Step-by-step explanation:

In this question, we have to find the distance of the two points.

To do so, we would use this equation: d = √(x2-x1)² + (y2-y1)²

Plug in your coordinates and solve:

d = √(4+2)² + (7-3)²

d = √(6)² + (4)²

d = √36 + 16

d = √52

Now, get the square root of 52:

d = 7.211103

The distance of each coordinate would be around 7.21

Y - Adds by -5X - Adds by 2

Step-by-step explanation:

It adds by negative 5 because if you add up all of the math and equations, it will all fit together.

Here's an example.

The first one is 3 and -2, so lets add -2 by 5.

-2 + 5 = 3 --- 1st row

We can figure this out by subtracting 2 by 5, which equals 3.

( This does not apply to all equations. )

Let's add all of them by 5 now.

-7 + 5 = -2 --- 2nd row

-12 + 5 = -7 --- 3rd row

On the last row, we add -12 by -5 and you get -17.

-17 + 5 = -12 --- 4th row

That's how you figure it out.
