A store is having a 10% sale on all items. There is an additional $30 discount to the sale price of any bicycle. Let x represent the price in dollars, and let f(x) = x − 30 and g(x) = x − 0.10x = 0.90x represent the discounts. Which function can the store manager use to find the final price of a bicycle?

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

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.
