Which glide reflection describes the mapping triangle abc to def

The correct option is A.

Step-by-step explanation:

The correct option is A.

If u notice the second transformation it would shift  triangle ABC 3 units to the left and reflect it across x = 4 so this will not map ABC into DEF.

If u notice first transformation it will shift triangle ABC 7 units down and reflect it across x=4 so this will map ABC into DEF.

Thus option A is correct

77

step-by-step explanation:

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.
