Answer:
So F(x+3) = (x+3+5)/2 = (x+8)/2
Step-by-step explanation:
Given F(2x-1) = x+2
Put 2x-1 = y=> x = (y+1)/2
Hence F(y) = (y+1)/2 +2 = (y+5)/2
So F(x) = (x+5)/2
So F(x+3) = (x+3+5)/2 = (x+8)/2.
Answer:
Henry has read per minute <u>3</u> pages.
Step-by-step explanation:
Given:
Henry is an avid reader. He devours 90 pages in half-an-hour.
Now, to find pages Henry has read per minute.
Let the number of pages Henry has read per minute be ![x.](https://tex.z-dn.net/?f=x.)
Number of pages he devours in half-an-hour = 90 pages.
So, as half an hour is 30 minutes.
Thus, number of pages he devours in 30 minutes = 90 pages.
Now, to get the pages he has read per minute:
According to question:
![30x=90](https://tex.z-dn.net/?f=30x%3D90)
Dividing both sides by 30 we get:
![x=3.](https://tex.z-dn.net/?f=x%3D3.)
Therefore, Henry has read per minute 3 pages.
