Karen wants to join buff gym. there is a $100 initiation fee, and then a $40 monthly fee. a) determine the equation that expresses the cost of joining this gym for x months. b) find the inverse function of the equation for part a.

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

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:
