Answer:
After 8 minutes will the temperature be 138.1 F
Step-by-step explanation:
Given that:
The water has been on the stove [tex]y=9.5x+62.1[/tex] .....[1]
where
y represents the temperature in Fahrenheit(F)
x represents the time in minutes.
We have to find after how many minutes will the temperature be 138.1 F.
⇒y = 138.1 F
Substitute the given value in [1] to solve for x;
[tex]138.1=9.5x+62.1[/tex]
Subtract 62.1 from both sides we get;
[tex]76=9.5x[/tex]
Divide both sides by 9.5 we get;
8 = x
or
x = 8 minutes.
Therefore, after 8 minutes will the temperature be 138.1 F
