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
Use the formula (b/2)^2 in order to create a new term. Solve for x by using this term to complete the square.
Exact Form:
x = ±√21 + 6
Decimal Form:
x = 10.58257569…, 1.41742430…

I hope this helps, as always. I wish you the best of luck and have a nice day, friend..
Answer:
it would be b for 1 since 7 would be negative and the 3 would be positive
