Answer:

El costo es:

Primero tenemos un cargo fijo de $140.

Luego tenemos un $25 por cada m^3 consumido.

Entonces, si tenemos x m^3 consumidos en un mes, el cargo de ese mes va a ser:

C(x) = $140 + $25*x.

Esto es una relación linear.

A) En este caso tendríamos x = 140

C(140) = $140 + $25*140 = $3640

B) La formula es, como ya escribimos arriba, C(x) = $140 + $25*x.

C) El grafico estará al final.  En el podemos ver que la linea corta el eje vertical en y = $140, que seria lo minimo que se puede pagar al mes, en el caso de que el consumo sea x = 0.

D) La ordenada al origen es $140, representa el cargo fijo que no depende de la variable x.

3f+2g=30 and f+2g=26
tatuchka [14]
3f + 2g = 30 . . .(1)
f + 2g = 26 . . . .(2)

(1) - (2) => 2f = 4 => f = 4/2 = 2

From (2), 2 + 2g = 26 => 2g = 26 - 2 = 24 => g = 24/2 = 12

Therefore, f = 2 and g = 12

Create a cylinder with a height of 9 cm and a radius of 5 cm. notice that the estimated volume calculation is 706.9 cm3. drag th
SpyIntel [72]

The volume of the cylinder with a height of 9 cm and a radius of 5 cm is 706.9 cm³, if the radius is doubled, the volume would be 2827.4 cm³ (4 times)

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more number and variables.

Volume of cylinder = π * radius² * height = π * 5² * 9 = 706.9 cm³

If the radius is doubled:

Volume of cylinder = π * (2 * 5)² * 9 = 2827.4 cm³

The volume of the cylinder with a height of 9 cm and a radius of 5 cm is 706.9 cm³, if the radius is doubled, the volume would be 2827.4 cm³ (4 times)

The best way to describe lines y= x+3 and -x+y=7
Alexandra [31]

Answer:

Parallel lines

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = x + 3 ← is in slope- intercept form

with slope m = 1

- x + y = 7 ( add x to both sides )

y = x + 7 ← in slope- intercept form

with slope m = 1

Parallel lines have equal slopes, thus the lines are parallel
