PLEASE HELP FAST Which equation and variable is the best choice to solve for, in order to substitute? please explain -2 +y = -4
3x + 2y = 12
a. top, y
b. top, x
c. bottom, y
d. bottom, x

Bottom x

Step-by-step explanation:

You can get rid of the y on the bottom by substititing the top one in. There is no X on the top.

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.
