Quadrilateral BCDE below was formed by 2 sets of intersecting parallel lines. Figure 2 is the image of
figure 1. It has been rotated 180. Find the center of rotation for figure 1. Make a list of everything that has been preserved in the rotation. Then make a list of anything that has changed.
Is quadrilateral BCDE a parallelogram? How do you know?

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

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.
