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.

Answer:

I'm not 100% sure, but I think the answer is 10 units squared.

Step-by-step explanation:

Find the area of each triangle, by multiplying each side, and dividing the answer in half. Add both of the triangles together, ending up as 6. Now we just find the area of the square. 2x2=4, add that to both of the triangles, and we're done. (2x2) ÷ 2 = 2 | (2x4) ÷ 2 = 4 | 2x2 = 4 | 4+4+2=10

Answer:

area=10 units^2

Step-by-step explanation:

[tex]a=\frac{(2+2+4)+(2)}{2} *2\\ =\frac{8+2}{2} *2\\ =\frac{10}{2} *2\\ =5*2\\ =10[/tex]

a=10 units^2

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)

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.

Answer:

area = x-2 * 5

perimeter = 2(x-2) + 10

Answer:

Step-by-step explanation:

Slope (m) =

ΔY

ΔX

=

9

7

= 1.2857142857143

θ =

arctan( ΔY )

ΔX

= 52.125016348902°

ΔX = 49 – 21 = 28

ΔY = 63 – 27 = 36

Distance (d) = √ΔX2 + ΔY2 = √2080 = 45.607017003966

Equation of the line:

y = 1.2857142857143x – 3.5527136788005E-15

When x=0, y = -3.5527136788005E-15

When y=0, x = 2.7632217501782E-15

If 1 Point and the Slope are Known:0.75

Answer:

Yes you are correct! :)

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.

Determine the number of possible positive and negative real roots of the equation:

x - 4x + 5x² + 9x² + 2x 8

a 2 or 0 negative roots; 3 or 1 positive roots

b. 5, 3, or 1 negative roots;

4, 2 or 0 positive roots

c.

d.

2 or 1 neative roots; 3 or 2 positive roots

3 or 1 negative roots; 2 or 0 positive roots

Answer:

Y=3/1x+25

Step-by-step explanation: I believe this is correct. I was doing this a while ago so I might have it wrong. Y Is the money on the card, m, or 3/1 is the slope. B is the Y-intercept, which is 25.

Answer:

4

Step-by-step explanation:

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.

Answer:

yes your formula is correct

Step-by-step explanation:

Answer:

The least common denominator is 12.

Step-by-step explanation:

Here's how I got my answer.

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:

It should be 75.4

Step-by-step explanation:

The formula for a cylinders volume is V=[tex]\pi[/tex]r^2h

so plugging those in would be

V=[tex]\pi[/tex](2)^2(6)= 75.4
