T(z)=z-8
T(-2)=-2-8 therefore
T(-2)=-10
Hope this helps.
Answer:
The second stove had a higher temperature when the stoves were turned off.
The first stove cooled down at a faster rate.
Step-by-step explanation:
first stove: T(t) = 180 - 2.55t can also be written as T(t) = -2.55t + 180
(180 is the y-intercept; -2.55 is the slope)
second stove = T(t) = mt + 200
(0,200) (40,130)
= = = -1.5
T(t) = -1.5t + 200

Answer:
P = 0.0909
Step-by-step explanation:
To know the number of ways or combinations in which we can select x elements from a group of n elements, we can use the following equation:
So, if you sat down at your computer and randomly loaded 4 of the 12 problems, there are 495 different possibilities and it is calculated as:
Then, from 495 different possibilities, there are 45 possibilities that both this problem and Richard Rusczyk's problem were among the four you loaded. This 45 possibilities are calculated as:
Because you need to select: this problem and there is only one, the problem that Richard Rusczyk wrote and there is only one, and 2 problems from the other 10.
Finally, the probability that both this problem and Richard Rusczyk's problem were among the four you loaded is equal to:
The situation can NOT be represented by that equation. The correct equation for net distance would be
If John were to reverse his direction and end his journey where he began, the equation for net distance would be
