The time(h), would be the independent variable and the temperature(C) would be the dependent variable.
Answer:
2x+20 + x+40 = 180
Step-by-step explanation:
The angles are supplementary so they add to 180
2x+20 + x+40 = 180
The difference between the 2 times would be .055 seconds...
Answer:

Step-by-step explanation:
We have to find the derivative of the following function:
Now, differentiating both sides with respect to x we get,
⇒
(Answer)
{Since, we know that,
and
}
The equation should be y= -2x+5.
