Question

The water has been on the stove y=9.5x+62.1 after how many minutes will the tempature be 138.1 F

Answer 1

Answer:

After 8 minutes will the temperature be 138.1 F

Step-by-step explanation:

Given that:

The water has been on the stove $y=9.5x+62.1$      .....[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;

$138.1=9.5x+62.1$

Subtract 62.1 from both sides we get;

$76=9.5x$

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
