Betty decides to support local artists by hanging their artwork in her shop. When decorating the coffee shop, Betty comes across the following formula for placing pictures on her walls: 1/3 |a-12|+ 2/3|a|where a equals the number of pictures that she would like to hang.
What is the value of this expression when a space equals space 9?
"when a space equals space 9"
you mean: a = 9 ??
Why not just plug in a = 9 and evaluate ?
btw, I have no clue what that formula is supposed to represent?
