What is the equation of this trend line?

Enter your answers by filling in the boxes.

Step-by-step explanation:

Take two points from the graph

(0,24) and (6,12)

Find the slope

The formula to calculate the slope between two points is equal to

substitute

---> is negative because is a decreasing function

Find the equation of the line in slope intercept form

we have

Note: The y-intercept is given (0,24)

substitute

he will have 300 because he is really broke and 300 is in his imangine

step-by-step explanation: he ehe heh step by the thy

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.
