Rate of change = 0.5
Initial value = 120
Step-by-step explanation:
(10 , 125) ; (30 , 135)
Slope = 

Rate of change = 0.5
Initial value = 120
Answer:
see explanation
Step-by-step explanation:
To calculate the first 3 terms substitute n = 1, 2, 3 into the n th term rule
= (3 × 1) + 2 = 3 + 2 = 5
= (3 × 2) + 2 = 6 + 2 = 8
= (3 × 3) + 2 = 9 + 2 = 11
------------------------------------------------------------------
substitute n = 10 into the n th term rule
= (3 × 10) + 2 = 30 + 2 = 32
No its smaller............................
Answer:
x = 3
Step-by-step explanation:
2x + 8 = 14
2x = 6
x = 3
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.
