Answer:
meow
Step-by-step explanation:
8 hr to read 288 pages
First find pages per hour so divide 72 pages by 2 hours to find per hour.
72/2 = 36 pageper hr
288 divided by 36 pages per hour is 8
We write f(x) in terms of y I.e y=7x-1/2.
Fractions are sometimes ambiguous, we eliminate the fraction by multiplaying the entire function by 2.so as to get 2y=14x-1.
Make x the subject, x=2y+1/14,
Thus the inverse f(x)=2x+1/14
777777878885087555
or
7.77777878 * 10^17
30:50 = 3:5
x : x+25 = 3:5
25/2 x 3 = 37.5
