Answer: w lesser than or equal to 4
Step-by-step explanation:
Dwight and Walt are building model cars.
Let d = the number of models built by Dwight.
Let w = the number of models built by Walt.
Dwight builds 7 fewer models than 4 times the number Walt builds. This can be expressed as
d = 4w - 7 - - - - - - - - - 1
Dwight builds at most 9 models. This is expressed as
d lesser than or equal to 9
From equation 1
d = 4w - 7
4w = d + 7
w = (d+7)/4
Assuming Dwight built 9 models
w = (9+7)/4 = 4
Therefore,
Walt builds at most 4 models. It is expressed as
w lesser than or equal to 4

Answer:
- 0.25|h -1600| -400
- 1000
- 2200
Step-by-step explanation:
Once again, you can choose the correct equation by finding the one that gives d=0 for h=0. (Note that the problem statement requires the independent variable to be h, not x.)
Then you can use that equation to find h for d=-250:
-250 = 0.25|h -1600| -400
150 = 0.25|h -1600|
600 = |h -1600|
This resolves to two equations:
- -600 = h -1600 . . . ⇒ . . . h = 1000
- 600 = h -1600 . . . ⇒ . . . h = 2200

Or, you can realize the distance from the west end is 4 times the depth. At a depth of 250 ft, that distance is h=1000 ft. That is 600 ft from the center, so 1200 ft from the same depth on the other side of the crater, which is at h=2200 ft.
