Answer :
Answer:
-22 ≤ temperature(F) ≤ 266
Step-by-step explanation:
Given that,
The label on the car's antifreeze container claims to protect the car between -30C and 130C.
Formula to convert Celsius temperature to Fahrenheit
C = 5/9 (F - 32)
9C/5 = (F - 32)
9C/5 + 32 = F
F = 9C/5 + 32
1)
-30C = ?F
F =9(-30)/5 + 32
F = -22
2)
130C = ?F
F =9(130)/5 + 32
F = 266
The inequality to determine the Fahrenheit temperature range at which this antifreeze protects the car is
-22 ≤ temperature(F) ≤ 266
