Which of the following is not a way to represent the solution of the inequality 5(x + 2) 7x + 2(x − 1)? A number line with a closed circle on 3 and shading to the right. A number line with a closed circle on 3 and shading to the left. 3 x x 3

In between the (x+2) Is greater than or equal to 7x+2(x-1)

okay so \[5(x + 2)\ge7x + 2(x-1)\] distribute the 5 into the parenthesis and the 2 into the other 5x + 10 is greater than or equal to 7x + 2x - 2 add 2 to boths sides 5x + 12 is greater than or equal to 7x + 2x 5x + 12 is greater than or equal to 9x subtract 5x from both sides 12 is greater than or equal to 4x divide by 4 x is less than or equal to 3 so if it's less than...it doesnt get shaded to the right..so its the first one :)
