Answer:
- 8° per hour
Step-by-step explanation:
Given that:
Station A = - 6°
Station B = 2°
Rate of temperature change = x° / hour ; which is the same at both stations
Temperature at station A 3 hours after the recording is the same as the temperature in station B 4 hours after the recording ;
Temperature change in Station A:
-6 + 3x
Temperature change in station B:
2 + 4x
Temperature change in A = temperature change in B
-6 + 3x = 2 + 4x
Collect like terms
3x - 4x = 2 + 6
- x = 8
x = - 8
Hence, the rate of temperature change x in both stations is - 8° per hour
Answer:
subtract 3 from both sides

Answer:
2
Step-by-step explanation:
x f(x)
−3 −1.5
−2 −1
−1 −0.5
0 0
1 0.5
2 1
3 1.5
This table shows the input and output values for a linear function f(x).
Now, two inputs which are four values apart are say -3 and 1 and the corresponding outputs are - 1.5 and 0.5.
Therefore, the positive difference of outputs is [0.5 - (- 1.5)] = 2 (Answer)
