The answer is x=2. Move 3x to the other side and subtract it from 6x. Then you have 6=3x. To get rid of the X divide both sides by 3. Then you get 2=x

The function f(x)=3x+12x+11 can be written in vertex form as?

solmaris [256]

y = -3(x - 2)^2 + 1 x-coordinate of vertex: x = -b/(2a) = -12/-6 = 2 y-coordintae of vertex: y(2) = -12 + 24 - 11 = 1 Vertex form: y = -3(x - 2)^2 + 1 Check. Develop y to get back to standard form: y = -3(x^2 - 4x + 4) + 1 = -3x^2 + 12x - 11.

David y Angie tienen dos cartulinas iguales. David corta la suya en 3 trozos iguales y Angie la corta en 7 trozos. Los dos usan

Bess [88]

Answer:

(i) David ha empleado $\frac{2}{3}$ de la cartulina.

(ii) Angie ha empleado $\frac{2}{7}$ de la cartulina.

(iii) David ha usado más cartulina.

Step-by-step explanation:

El problema indica que David y Angie emplean una cartulina del mismo tamaño cada uno. David corta la suya en 3 pedazos iguales, mientras que Angie obtiene 7 pedazos iguales. Finalmente, cada uno emplea dos de sus pedazos. A continuación, respondemos a las preguntas del enunciado:

(i) ¿Qué fracción de cartulina ha usado David?

La fracción de cartulina empleada por David es igual a los pedazos utilizados divididos por el total de pedazos. Esto es:

$x = \frac{2}{3}$

David ha empleado $\frac{2}{3}$ de la cartulina.

(ii) ¿Qué fracción de cartulina ha usado Angie?

Aplicando el mismo procedimiento del punto anterior, tenemos que:

$x = \frac{2}{7}$

Angie ha empleado $\frac{2}{7}$ de la cartulina.

(iii) ¿Quién ha usado más cartulina?

La persona que ha usado la mayor cantidad de cartulina es aquella que tiene el menor denominador. Por tanto, David ha usado más cartulina.

A right triangle ABC is shown below:

barxatty [35]

The answer is: "4" .
______________________________________________________
Note: The question asks for a whole number.

"The area of the triangle above will equal one half of a rectangle that is 5 units long and  4  units wide. (Input only whole numbers, such as 8.).
______________________________________________________
Note: The diagram shows a "right triangle" ; which would be "one-half" of a rectangle, with units of "length" being "5 units" (as mentioned in this very question prompt; and a width of "4" units (as shown in the diagram; hence the answer is "4" units).

Furthermore, the formula/equation for the area, "A" , of a triangle is:

A = (1/2) * b * h ;

that is:

Area = (1/2) * (base length) * (perpendicular height).
_________________________________________________
As such, the answer, "4" (units) makes sense.

A rectangular pyramid has a volume of 315 cm^3. The base has a width of 15 cm and a length 7 cm. Find the height h of the pyrami

pochemuha

Answer:

h = 9 cm

Step-by-step explanation:

A rectangular pyramid has a volume of 315 cm^3.

The base has a width of 15 cm and a length 7 cm.

Find the height h of the pyramid .

Vol = 1/3 (base area) h

where base area = 7 x 15 = 105 cm²

vol = 315 cm³

plugin values into the formula

315 = 1/3 (105) h

h = 315

(1/3 * 105)

h = 9 cm
