F(7) means f(x) when x = 7. The x is replaced with 7.
So we'll replace every x with 7 to go from x = 7 to 3-x = 3-7 = -4
Put another way
f(x) = 3-x
f(7) = 3-7
f(7) = -4
Answer: -4
Given:
x = number of hours
y = total number of pages
70 = number of pages already read
30 =number of pages read per hour
y = 30x
70 = 30x
70/30 = 30x/30
2 1/3 = x
You read 70 pages within 2 hours and 20 minutes.
y = 30x
y = 30(3)
y = 90
An additional 90 pages have been read after another 3 hours.
Total pages read.
y = 30(2 1/3) = 70 pages
y = 30(3) =<u> 90 pages</u>
160 pages within 5 hours and 20 minutes.
