Answer:
- a) f(x) = - 20x + 450
- b) 30 pages left to read
Step-by-step explanation:
<u>Given sequence:</u>
The first term is 430 and the common difference is - 20.
a)
<u>Required function is:</u>
- f(x) = 430 - 20Ix - 1) = 430 - 20x + 20 = 450 - 20x
or
b)
<u>Find the number of pages left after 21 days:</u>
- f(21) = 450 - 20*21 = 450 - 420 = 30
Answer:
To work this problem out you would do it as if it were just a simple equation
7x-19<16 (you would first have to add 19 to both sides)
7x<35 (then you would divide by 7 to get the variable by itself)
x<5 ( you answer would then be 5)
