how do you translate a figure in a coordinate plane?

Answers

Answer:

Answer down below

Step-by-step explanation:

When you perform translations, you slide a figure left or right, up or down. This means that on the coordinate plane, the coordinates for the vertices of the figure will change. To graph a translation, perform the same change for each point. You can identify a reflection by the changes in its coordinates.

Se ha construido un cuadrado sobre cada lado del triángulo rectángulo, Pitágoras dice que el cuadrado de área 25 cm2, es igual a sumar las áreas de los otros dos cuadrados, es decir, 16 cm2 y 9 cm2. Escribir la expresión algebraica que mejor represente la relación entre las áreas en la figura.

Answers

Answer:

Tenemos la siguiente expresión algebraica:

[tex]c^{2} = a^{2}+b^{2}[/tex] (1)

Donde:

[tex]c[/tex] - Hipotenusa, en centímetros.

[tex]a, b[/tex] - Catetos, en centímetros.

Step-by-step explanation:

Este ejercicio ofrece un recurso mnemotécnico para la comprensión y aplicación del Teorema de Pitágoras, el cual establece que el cuadrado de la hipotenusa es igual a la suma de los catetos elevados al cuadrado, siendo cada componente equivalente al área de un cuadrado hipotético, entonces, la expresión algebraica que representa esa relación entre las áreas es:

[tex]25\,cm^{2} = 16\,cm^{2} + 9\,cm^{2}[/tex]

[tex](5\,cm)^{2} = (4\,cm)^{2}+(3\,cm)^{2}[/tex]

Por analogía, tenemos la siguiente expresión algebraica:

[tex]c^{2} = a^{2}+b^{2}[/tex] (1)

Donde:

[tex]c[/tex] - Hipotenusa, en centímetros.

[tex]a, b[/tex] - Catetos, en centímetros.

Write the equation for a line that passes through (4,-1) and has a slope of 5

Answers

Answer:

y = 5x - 21

Step-by-step explanation:

Since we already know the slope, all we need to do is plug the values of x and y into the equation.

y = 5x + b

-1 = 5(4) + b

-1 = 20 + b

-21 = b

The equation is y = 5x - 21.

Given: the function f defined by f(x) = 3x2 . Which statement is true? 1) f(0) = 0 2) f(−2) = f(2) 3) f(5) + f(2) = f(7) 4) f(5) − f(2) = f(10)

Answers

Answer:

f(0) = 0 and f(−2) = f(2)

Step-by-step explanation:

Given: the function f defined by f(x) = 3x²

f(0) = 3(0)²

f(0) = 0

f(-2) = 3(-2)²

f(-2) = 3(4)

f(-2) = 12

f(2) = 3(2)²

f(2) = 3(4)

f(2) = 12

Hence f(-2) = f(2)

Therefore the correct options are  f(0) = 0 and f(−2) = f(2)

First, I listed out the multiples of 4, which is the denominator of 1/4.

4: 4, 8, 12, 16

Next, I listed out the multiples of 3, which is the denominator of 2/3.

3: 3, 6, 9, 12

The smallest number they have in common is 12.

Therefore, the least common demoninator (LCM) is 12.

Answer:

12, 6, 4, 3, 12/7

Step-by-step explanation:

so for each column, you would substitute the number for a in the equation. for example, substituting 2 for a will make the equation 2/2 + b = 12. we now need to isolate b. 2/2(2/2 + b) = 12(2/2) makes the new equation b = 24/2, or b = 12.

Answer:

11,10,9,8,5

Step-by-step explanation:

look at the table.

they are giving you what a equals.

for example: in the table, it says a is 2. SO you put that into the equation you are given.

[tex]\frac{a}{2}[/tex] + b = 12 substitute "a" which we know is 2 into the equation

[tex]\frac{2}{2}[/tex] + b = 12  NOW you solve for b

first, divide 2 by 2 which equals 1

THEN subtract 1 by 12 giving you 11. The equation should look like this

b = 11

11 can then go under 2 on the table.

Do this for the rest of the answers.
