式33: 6 less than "y" less than 19.3 5 left brace, 4 less than "x" less than 10 , right brace6<y<19.354<x<10
33
Right here, I changed the equal to > and put the 6 on the other side to cut off the shading at 6
34
式35: 6 greater than "y" greater than or equal to left parenthesis, .5 1 "x" minus 3.2 5 , right parenthesis cubed left brace, 5.9 less than "x" less than 10 , right brace6>y≥.51x−3.2535.9<x<10

39
Here I multiplied both sides by negative one and put the restriction of 6
