Marcus currently owns 200 songs in his itunes collection. every
month, he adds 15 new songs. write a formula for the number
of songs, n, in his itunes collection as a function of the number
of months, m. how many songs will he own in a year?

Marcus will own 380 songs after a year.

Step-by-step explanation:

the equation would look like

you

then put 12 in for (m)

n=15(12)+200

n=180+200

n=380

Marcus will own 380 songs after a year.

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
