The domain represents the time traveled. It is any positive number.
Let E=elevation range
Low elevation=1700≤E≤2500<span>
Mid elevation= 2500</span>≤E≤4000<span>
Sulbarine=4000</span>≤E≤6500<span>
Alpine=6500</span>≤E<span>≤14,410</span>
Answer:
x< - 
Step-by-step explanation:
x 8x_16>8x+64
Add similar elemants:x - 8x= -7x
-7x - 16 > 8x + 64
Add 16 to both sides
-7x- 16 + 16 > 8x + 64 + 16
Simplify
- 7x > 8x + 80
Subtract 8x from both sides
-7x - 8x > 8x + 80 - 8x
Simplify
-15x > 80
Multiply both sides by - 1 ( reverse the inequality)
(-15x) ( - 1) < 80 ( - 1 )
simplify

18 degrees F because
it dropped 12 degrees=10 hours
x degrees=15 hours
x is what you want to find out which is how many degrees it would drop in 15 hours.
12x15 then divided by 10 is 18.
Answer:
7 hours
Step-by-step explanation:
12hrs=1116kms
1hr=1116÷12
1hr=93kms
Xhrs=651kms
Xhrs=(651÷93) ×1
=7×1
=7hrs
