Answer:
The value of x>-10
Step-by-step explanation:
The interval notation if you need it is (-10,♾)
Answer:
1/4
Step-by-step explanation:
1/4 x 2 = 1/2
1/2 divided by 2 is 1/4
Plane #1 speed: x mph
Plane #2 speed: (x+30) mph
time = time becomes
170 mi 185 mi
---------- = --------------
x x+30
Solving for x, the speed of the slower plane, we get
170x + 5100 = 185 x
5100
Then 15x = 5100, and x = ---------- (mi/hr) = 340 mph
15
The slower plane flies at 340 mph, and the faster one at 370 mph.
