Write a story that could describe the expression: -9 - 5x

Jacob lent a book from the library. He has to pay $9 for the first 5 days and $5 for every subsequent week. Write an expression that will subtract the money from his savings after x weeks from the fifth day.

For the first 5 days, he has to pay $9.

-9 will model this situation.

After the fifth day, he has to pay $5 per week. So, for x weeks, he has to pay $5x.

Therefore, the required expression is -9 - 5x.

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
