Yolanda is riding her bike. the number of revolutions (turns) her wheels make varies directly with the distance she travels. see the graph below.

how far does yolanda travel per revolution

what is the slope of the graph

Step-by-step explanation:

The straight line graph is that of the number of revolutions on the vertical axis against distance travelled in feet on the horizontal axis.

Slope = change in the value of y on the vertical axis/ change in the value of x on the horizontal axis

Slope = (y2 - y1)/(x2 - x1)

Slope = (6 - 2)/(24 - 8) = 4/16 = 1/4 revolution per feet.

It means that in 1 feet, Yolanda makes 1/4 revolutions. Therefore, The distance that Yolanda travels per revolution would be

1/(1/4) = 1/0.25 = 4 feet

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.

ok so what's the question?
