5 0

Answer:

y=(x+4)/12

Step-by-step explanation:

f(x)=12x-4

To find the inverse follow these steps:

1.) Make f(x) y so y=12x-4

2.) Switch x and y

so, x=12y-4

3.) solve for y

add 4 to the other side and then divide by 12 to get y by itself.

Josh and Greg leave from the same place
nasty-shy [4]

9514 1404 393

Answer:

  • Josh: 32 mph, 64 mi
  • Greg: 64 mph, 320 mi

Step-by-step explanation:

Let x represent Josh's rate of travel in miles per hour. After 2 hours, his distance is ...

  distance = speed · time

  distance = x · 2 = 2x

Then 2x is Greg's rate of travel After 5 hours, his distance is ...

  distance = speed · time

  distance = (2x) · 5 = 10x

The distance they are apart is ...

  10x -2x = 256

  8x = 256

  x = 32

__

Josh's rate: 32 miles per hour; Josh's distance = (2 h)(32 mi/h) = 64 miles.

Greg's rate: (32 mi/h)·2 = 64 mi/h; Greg's distance = (5 h)(64 mi/h) = 320 miles.

<em>__</em>

<em>Check</em>: 320 miles - 64 miles = 256 miles . . . . correct separation
