Answer:
C
Step-by-step explanation:
ley y = f(x) and rearrange making x the subject
y = 
- 1 ( add 1 to both sides )
y + 1 = ( multiply both sides by (x + 5)
(y + 1)(x + 5) = 1 ← expand factors using FOIL
xy + 5y + x + 5 = 1 , that is
xy + x + 5y + 5 = 1 ( factor first/second and third/fourth terms on left side )
x(y + 1) + 5(y + 1) = 1 ← factor out (y + 1) from each term on left side
(y + 1)(x + 5) = 1 ( divide both sides by (y + 1) )
x + 5 = 
( subtract 5 from both sides )
x = - 5
Change y back into terms of x with x = 
(x) , then
(x) = 
- 5 where x ≠ - 1
Answer:
x = 0
Step-by-step explanation:
Take out common factor
The factor inside the parenthesis cannot be factored
Since there is a common factor that we pulled out of the original equation,
set that x equal to zero and solve
: Therefore x = 0
Answer:
Guo Qi requires 75 days to watch videos on Khan Academy.
Step-by-step explanation:
We are given the following in the question:
Number of videos watched by Guo Qi each day = 15
Average length of each video = 8 minutes
Total minutes of video = 9000 minutes
Total number of videos to be watched =
Guo Qi needs to watch 1125 videos.
Number of days required =
Guo Qi requires 75 days to watch videos on Khan Academy.
