x = 50
The angles shown are vertically opposite and thus equal
so 3x - 30 = 2(x + 10)
3x - 30 = 2x +20
subtract 2x from both sides
3x - 2x - 30 = 20
x - 30 = 20
add 30 to both sides
x = 20 + 30 = 50
Upstream: 14 - 4 = 10. Miles per hour.
16 miles = 1.6 hours.
Downstream: 14 + 4 = 18.
16 miles = 16/18 = 8/9 or 0.888 of an hour.
Answer:
8/2, 12/3, 20/4
Step-by-step explanation:
Answer:
Step-by-step explanation:
The graph of the absolute value function looks like a V that opens UP and has its vertex at the origin, (0, 0). There are no restrictions on the input, x, so the domain is (-infinity, infinity).
On the other hand, this function has no values less than zero. Its range is
[0, infinity).
