You drive at an average speed of 60 miles per hour. you already drove 2 hours and you still have 210 miles left to travel. which graph shows how far you are from your destination at any given time?

The second graph is the correct answer. This is because we are driving 60 miles per hour and we already drove for 2 hours meaning we drove 120 miles so far. However, we 210 miles left to go. 210 + 120 = 330 miles is where we started at. Graph one shows the incorrect mile distance and graph 3 shows the incorrect mile count, too. Only graph 3 shows the correct mile count.

The second graph is the corrects answer!    

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.
