Answer:
8 minutes
Step-by-step explanation:
To answer this, set the function y = 9.5x + 62.1 = to 138.1 and solve the resulting equation for x:
9.5x + 62.1 = 138.1
We must isolate x. Start this process by subtracting 62.1 from both sides of this equation, obtaining:
9.5x = 76
Now divide both sides of this equation by 9.5:
x = 76/9.5 = 8
The water reaches 138.1 degrees F after 8 minutes.
