Answer: A) when Celsius (c) = 0, then Fahrenheit (F) = 32
B) F(100) = 212°
C) F(25) = 77°
Step-by-step explanation:
A) F(c) = 32 means that when c = 0 then F = 32
B) when c = 100°, then F = 212° can be written as: F(100) = 212°
C) [tex]\dfrac{F(100)-F(0)}{100-0}=\dfrac{212-32}{100}=\dfrac{180}{100}=1.8[/tex]
F(c) = 1.8c + 32
F(25) = 1.8(25) + 32
= 45 + 32
= 77°
