Step-by-step explanation:
Here, the given question is INCOMPLETE.
The complete question is:
Evaluate the expression for a = 4, b = -5, and c = -7. 
Here, substitute the vale of a = 4, b = -5 and c = -7, we get:
Hence, the value of the given expression is -878.08.
Answer:
3-(X) +2 -(Y)
Step-by-step explanation:
Answer:
Step-by-step explanation:
To find the inverse function, the first step we do is change f(x) to Y. So now, we have
y=2x+1
Now that we have this function, we simply flip x and y. When we do that, we get
x=2y+1
Now that we have this function, we just solve for Y. We do that by bring 1 to the other side by subtracting it from both sides, then dividing both sides by 2.
x-1=2y+1-1
x-1=2y
(x-1)/2=2y/2
(x-1)/2=y
So, our inverse function is:
y=(x-1)/2, or y=x/2 - 1/2

The number of hours it take to watch the series twice is 18.25 hours.
<h3>
Number of hours</h3>
First step is to calculate the time it takes to watch it twice
Time=2×3.285×10^4
Time=6.57×10^4 seconds
Second step is to convert the second into hour
1 hours=3600 second
Hence:
6.57/3600×10^4
18.25 hours
Inconclusion the number of hours it take to watch the series twice is 18.25 hours.
