The best answer would be y=-x+9

you can eliminate c because the -9 would mean it would start below the x-axis. you can eliminate both a and b because the slope of the line can be shown as 1/1 which would just be x.

0.2.0.4, 0.6, 0.8, 1....<br> Arithmetic or geometric
Basile [38]

Arithmetic sequences have a common difference between consecutive terms.

Geometric sequences have a common ratio between consecutive terms.

Let's compute the differences and ratios between consecutive terms:

Differences:

0.4-0.2 = 0.2,\quad 0.6-0.4=0.2,\quad 0.8-0.6=0.2,\quad 1-0.8=0.2

Ratios:

\dfrac{0.4}{0.2}=2,\quad \dfrac{0.6}{0.4} = 1.5,\quad \dfrac{0.8}{0.6} = 1.33\ldots, \quad\dfrac{1}{0.8}=1.25

So, as you can see, the differences between consecutive terms are constant, whereas ratios vary.

So, this is an arithmetic sequence.

The telephone company offers two billing plans for local calls. Plan 1 charges $36 per month for unlimited calls and Plan 2 char
Katyanochek1 [597]

Answer:

After 460 calls plan 1 is more economical than plan 2

Step-by-step explanation:

Plan 1: 36x + 0y

Plan 2: 13x + 0.05y

36x < 13x + 0.05y

36x - 13x < 0.05y

23x < 0.05y

23/0.05x < y

460x < y

Calcula la longitud en YARDAS de
tatiyna

Answer:

Las longitudes solicitadas en yardas son:

  • <u>Trayecto A = 109.361 yardas.</u>
  • <u>Trayecto B = 20.231785 yardas.</u>

Step-by-step explanation:

Para hacer la conversión de unidades que requieres en el ejercicio, debes saber que:

  • 1 metro = 1.09361 yardas

Con ese factor de conversión tú puedes hacer reglas de tres para calcular las medidas que requieres. En el caso del trayecto A:

Si:

  • 1 metro = 1.09361 yardas
  • 100 metros = X

Entonces:

  • x=\frac{100m *1.09361yardas}{1m}

Cancelamos metros y obtenemos:

  • x = 100 * 1.09361 yardas
  • <u>x = 109.361 yardas</u>

En este caso, <u>el trayecto A en yardas corresponde a 109.361 yardas</u>. El mismo procedimiento puede aplicarse para el trayecto B:

Si:

  • 1 metro = 1.09361 yardas
  • 18.50 metros = X

Entonces:

  • x = \frac{18.50m*1.09361yardas}{1m}

Cuando se cancelan los metros se obtiene:

  • x = 18.50 * 1.09361 yardas
  • <u>x = 20.231785 yardas</u>

Así, <u>el trayecto B en yardas corresponde a 20.231785 yardas</u>.
