Answer:
x < -3 1/2 or 3.5
Step-by-step explanation:
-9x + 5 < 17
13x +25 < -1
If we add the 2 equations together, we will have
4x + 30 < 16
4x < 16 - 30
4x < -14
Divide both sides by 4
x< -14/4
x < -3 1/2 or 3.5
Answer:
1.72 ≤ t ≤ 1.85
Step-by-step explanation:
Given :
Distance = 100 miles ;
Speed = 56 miles per hour, to the nearest 2 miles per hour
Hence, the speed range is :
(56 - 2) mph ; (56 + 2) mph
Range of possible Time taken, t :
Distance / speed ;
100 / 58 ≤ t ≤ 100 / 54
1.72 ≤ t ≤ 1.85
Answer:
55.5F
Step-by-step explanation:
y = mx + b
m = slope = -3.5/1000
distance = x = 1000
b = temperature at x = 0 = 59F according to https://www.universalweather.com/blog/international-standard-atmosphere-how-it-affects-flight-understanding-the-basics/
temperature = y = ?
y = -.0035(1000) + 59
y = 55.5
