Hello,
What do you want?
a(2)=4*a(1)==>a(1)=12/4=3
a(0)=3/4
a(n)=3/4 * 4^n (genearl term)
First you need to find the common denominator. Think of a number that both 2 and 5 can go in to evenly. 10 is the best number, so, make both denominators 10. What you do to the bottom, you must do to the top.
Now your equation is 5/10-2/10
Your answer is 3/10
Answer:
r = 2.5
Step-by-step explanation:
4 X 2.5 = 10
5 x 2.5 = 12.5
10 x 2.5 = 25
Answer:

Step-by-step explanation:
The correct question is
Naoya read a book cover to cover in a single session, at a rate of 55 pages per hour. After 4 hours, he had 350 pages left to read.
Let y represent the number of pages left to read after x hours.
Complete the equation for the relationship between the number of pages left and number of hours.
Let
x -----> the time in hours
y ----> the number of pages left to read
we know that
The linear equation in point-slope form is equal to

In this problem we have
----> is negative because the linear function is decreasing

substitute
