Answer:

-3/2

Step-by-step explanation:

The slope of a line is calculated by finding the rise over run of two points on the line. In this case, I use the points (-3, 4) and (1, -2). Then, I use the formula of [tex]\frac{y_{2} - y_{1}}{x_{2}- x_{1} }[/tex]  to find the slope. If 4 is [tex]y_{2}[/tex], -3 is [tex]x_{2}[/tex], 1 is [tex]x_{1}[/tex] and -2 is [tex]y_{1}[/tex], then,

[tex]\frac{4 - (-2)}{ -3- 1 } = \frac{6}{-4} = \frac{3}{-2}[/tex]

Furthermore, the slope of a parallel line is always the same as the given line. Therefore, the answer is -3/2.

Answer:

Top Right

Step-by-step explanation:

all the brackets are in the form (X, Y), Y=P(x)

just replace the X's in the brackets with the X's in the Options, if P(x) is the number that's in place of Y in the brackets, then that option is the correct one, in this case the top Right one. if this helped, please mark as brainliest

Answer:

Top right/second answer is correct

Step-by-step explanation:

I did it

Answer:

X=18

Step-by-step explanation:

To isolate X you need to get rid of the -15 to do that you can add 15 on both sides of the equation resulting in 3x=54 now you need to divide both sides by 3 to get x on its own which is X=18.

Si el año es ordinario, entonces Raquel y Beatriz se encontrarán el 8 de febrero, más si el año es bisiesto, entonces se encontrarán el 7 de febrero.

El período de coincidencia es el tiempo que pasa entre dos fechas en las que Raquel y Beatriz coinciden y queda determinado por el mínimo común múltiplo de los tiempos de frecuencia de cada una. En este caso, el período de coincidencia corresponde a 12 días.

Si tenemos que coincidieron el 24 de febrero, debemos considerar dos posibilidades: (i) Año ordinario, (ii) Año bisiesto.

Answer:

Sequence 1: Translate 5 units to the right, and 5 units down

Sequence 2: Reflect across the origin, translate 1 unit down, 1 unit to the right

Step-by-step explanation:

Chose 1 point to focus in, such as (-1, 1)

Move that point 5 units to the right, and 5 units down. See how it matches up with the same corner of the red square?

Now, use that same point, and change the signs of both the x and y, this is to reflect across the origin. (In reality, you are just reflecting across the x and y axis)

So you originally have: (-1,1) -> (1, -1)

Now move this point one unit to the right, and 1 unit to the left.

It may seem that you made it touch the wring corner, but do the same thing with another corner's points. They all flipped!

Answer:

2/5 * 4/5 =  8/25        7/9 * 2/3 = 14/27   4/7 * 2/3 = 8/21  1/6 * 7/8 = 7/48  2/3 *3/9 = 2/9

Step-by-step explanation: Just multiply the top with top and bottom with the bottom    To draw = just use a ruler for the width  we know if you measure the square box say it is already { 20 mm } wide  then you 2 * 4 = 8 is 2/5 of 20 so you shade the 8mm    Then to get the 4 as ultiplier we know 20/5 =4

Answer:

Step-by-step explanation:

Let's start by decoding this :)

First lets do 60% more than 10; 16 (mental math)

Next, lets do 20% less than 16;  x/16 = 80/100 (Equation)

After solving by cross multiplying & then simplifying (make sure both denominators are 100), you should get 12.8 as your final #! Hope this helped.

Answer:

The statement (A) Electrons can have a measured radius. and statement (D) Electrons do not have energy, the energy is determined by the orbit are correct.

In the Bohr atomic model, electrons are grouped according to their energy levels. The energy level at which an electron is located determines its energy.

As we know,

The aspects covered by Bohr’s atomic model are:

Energy is absorbed by electrons as they transition from a lower to a higher energy state. The electron emits energy when it transitions from a higher to a lower energy level. Visible light is one way to view this energy.

Thus, the statement (A) Electrons can have a measured radius. and statement (D) Electrons do not have energy, the energy is determined by the orbit are correct.

Answer: Electrons do not have energy, the energy is determined by the orbit." or A and b

Step-by-step explanation: The correct answer is, "Electrons do not have energy, the energy is determined by the orbit."

In the Bohr model of the atom, electrons are arranged in energy levels. The energy of an electron is determined by the energy level in which it is found.

When electron an the  electron moves from a lower to a higher energy level it absorbs energy. When the electron moves from a higher to a lower energy level, it radiates energy. This energy is observed in the form of visible light.

Thus, in the Bohr's model, electrons are arranged in energy levels. The energy level where an electron is found determines its energy.

Answer: He will save $57.80

Step-by-step explanation: Sale Price = $57.8. This means the cost of the item to you is $57.8. You will pay $57.8 for an item with original price of $68 when discounted 15%. In this example, if you buy an item at $68 with 15% discount, you will pay 68 - 10.2 = 57.8 dollars.

Answer:

[tex]\tt{} x_{1} = 4 \\ \tt{} x_{2} = 5 \\ [/tex]

Step-by-step explanation:

[tex]\tt{} \sqrt{ {x}^{2} - 16 } - 3 \sqrt{x - 4} = 0[/tex]

[tex]\tt{} \sqrt{ {x}^{2} - 16 } = 3 \sqrt{x - 4} [/tex]

[tex]\tt{}{x}^{2} - 16 = 9(x - 4)[/tex]

[tex]\tt{}(x - 4).(x + 4) = 9(x - 4)[/tex]

[tex]\tt{}(x - 4) \times (x + 4 - 9) = 0[/tex]

[tex]\tt{}( x - 4) \times (x - 5) = 0[/tex]

[tex]\tt{}x - 4 = 0 \\ \tt{}x - 5 = 0[/tex]

[tex]\tt{}x = 4 \\ \tt{}x = 5 \\ \\ [/tex]

[tex]\tt{} x_{1} = 4 \\ \tt{} x_{2} = 5 [/tex]

Answer:

x = 4, 5.

Step-by-step explanation:

√(x^2 - 16) - 3√(x - 4) = 0

√(x^2 - 16) = 3√(x - 4)

Square both sides of the equation:

x^2 - 16 = 9(x - 4)

x^2 - 9x - 16 + 36 = 0

x^2 - 9x + 20 = 0

(x - 4)(x - 5) = 0

x = 4, 5.

As the original equation contained square roots:

We test for extraneous solutions:

x = 4:

√(4^2 - 16) - 3√(4 - 4) = 0 - 3*0 = 0  so x = 4 is OK.

x = 5:

√(5^2 - 16) - 3√(5 - 4) = √9 - 3√1 = 0  so x = 5 is also OK.

Answer:

(-7, -7)

Step-by-step explanation:

1. Let's ONLY focus on point C.

2. The algebraic rule for reflecting across the y-axis is (x, y) -> (-x, y).

3. The algebraic rule for translating 8 units down is (x, y) -> (x, y - 8).

Therefore, the coordinates for C' are (-7, -7).
