For each increment in x, the output is multiplied by 2. The function could be written the way a geometric sequence can be written:
... f(x) = 5·2^(x-1)
Or, it could be simplified to ...
... f(x) = (5/2)·2^x
The first 5 terms will be
... 5, 10, 20, 40, 80
So x is one number and x + 1 is another
1. x + x + 1 = 57;
2. 2x + 1 = 57;
-1 -1
4. 2x = 56
5. x = 56/2
6. x = 28
So, x + 1 = 28 + 1 = 29
So 28 and 29 are the 2 consecutive integers of 57
Answer:
$706.77 total cost of bicycle
Step-by-step explanation:
$658.99 x .0725 = $47.776 (Move decimal twicw to left to change to decimal)
$658.99 + $47.776 = $706.766 = $706.77
Notice that it goes from 120 to 30....so we are dealing with a decrease
percent decrease = (original number - new number) / original number..* 100
= (120 - 30) / 120....* 100
= 90/120...* 100
= 0.75 * 100
= 75% decrease <===
