The temperature after 7 hours is -2° F

Explanation

At 3 p.m the temperature was 12° F

Then , the temperature began to drop 2° F every hour.

So, the total temperature dropped in 7 hours will be: $(2*7)=14$ ° F

Now, for finding the temperature after 7 hours, we need to subtract the "temperature dropped" from the "initial temperature".

Thus, the temperature after 7 hours $=12-14= -2$ ° F

Find any points of discontinuity for the rational function. y=x-5/x^2-7x-8

kotegsom [21]

For discontinuity of the function:
x² - 7 x - 8 ≠ 0
x² - 8 x + x - 8 = 0
x ( x - 8 ) + ( x - 8 ) ≠ 0
( x - 8 ) ( x + 1 ) ≠ 0
The points of discontinuity are: x = - 1 and x = 8.
As for the Domain of the function:
x ∈ ( - ∞, - 1 ) ∪ ( - 1 , 8 ) ∪ ( 8, +∞ ).
