Answer:

2

Step-by-step explanation:

You'll need to find the reciprocal of m. -1/4 is your is your m and when you find the reciprocal you flip the number to 4/1 or 4 and change the negative to a positive. Then graph (4,11), you don't need to worry about your y intercept, b, or -1. On your graph go down 4 and over one to the left because it's positive the line should be going like " / "  <-- that. Keep going down until your y is three and whatever your x is, is your answer. Ex: (4,11) (3,7) (<u>2</u>,3). Hopefully, you understand :)

Breanna has $150 and she needs to save at least $560 for spring break trip if she can save $45 per week how long will it take he
melamori03 [73]

Answer: It will take her more than 9 weeks.

Step-by-step explanation:

If she already has $150 that will be constant and if she can save $45 per week  the we will have the expression 45w  where w is the number of weeks.

Together it will  be  150 + 45w    

Now the money has to be at least $560  so it will be

150 + 45w ≥ 560  Now solve for w

-150              -150

45w ≥ 410

w ≥ 9.1  

Which means it will take 10 or more weeks t

La distancia entre la tierra y el sol es de 1,5 . 10˄8 km, la distancia entre la Tierra y Júpiter es de 9,3 . 10˄8 km y Neptuno
Sonbull [250]

A) La distancia del Sol a Neptuno en notación científica es 45 x 10^8 km.  

B) Júpiter se encuentra a 930.000.000 kilómetros del Sol.  

C) La distancia del Sol a Neptuno es 30 veces mayor que la que hay a la Tierra.

Dado que la distancia entre la tierra y el sol es de 1,5 . 10˄8 km, la distancia entre la Tierra y Júpiter es de 9,3 . 10˄8 km y Neptuno está situado a 4.500.000.000 Km del Sol, para determinar:

A) Expresa en notación científica la distancia del sol a Neptuno  

B) Calcula la distancia a la que está situado Júpiter respecto al Sol  

C) Calcula cuantas veces es mayor la distancia del Sol a Neptuno que la que hay a la Tierra.

Deben realizarse los siguientes cálculos:

  • A) 4.500.000.000 = 45 x 100.000.000
  • 100.000.000 = 10^8
  • 4.500.000 = 45 x 10^8

  • B) 9.3 x 10^8 = X
  • 100.000.000 = 10^8
  • 9.3 x 100.000.000 = X
  • 930.000.000 = X

  • C) Tierra = 150.000.000
  • Neptuno = 4.500.000.000
  • 150 = 1
  • 4.500 = X
  • 4500 / 150 = X
  • 30 = X
