identify the type of function that models the labor cost of repairing a computer if the charge is $50 per hour or fraction thereof

 Linear

Step-by-step explanation:

Labor Cost = $50 per hour      →      y = 50x

Since x has an exponent of 1, it is a linear function.

Bonus:

exponent of 2: quadratic function

exponent of 3: cubic function

exponent of 4: quartic function

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.
