How do I do this? It's a modulus question.

1 answer:

6 0

1)
||x|-4|= |x-1|
1st step = separate the equation into 2 possible equations
2nd step = solve the equations
|x|-4= x-1
x= -3/2
Or
|x|-4= - (x-1)
X= 5/2

2)

Do the same
X= -5/2
X= 7/2

7.6.35 Question Help A pilot can travel 400 miles with the wind in the same amount of time as 352 miles against the wind. Find t

Law Incorporation [45]

9514 1404 393

Answer:

21 miles per hour

Step-by-step explanation:

Let w represent the wind speed. Then the travel time is ...

400/(329 +w) = 352/(329 -w)

400(329 -w) = 352(329 +w)

(352+400)w = 329(400 -352)

w = (400 -352)/(400 +352)·329 = 48/752·329 = 21

The wind speed is 21 miles per hour.
