The domestic postage rate for first-class letters weighing 3.5 oz or less is 39 cents for the first ounce (or less), plus 16 cents for each additional ounce (or part of an ounce).
express the postage p in dollars as a function of the weight x of a letter, with 0 < x ≤ 3.5, and sketch the graph of this function.
p(x) = $
if 0 < x ≤ 1 $
if 1 < x ≤ 2 $
if 2 < x ≤ 3 $
if 3 < x ≤ 3.5

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.

step-by-step explanation:

they disappear if your absent from to long. i found out that the hard way.

brainliest lol i just need one more brainliest.
