If the circle is colored in I just think it means extra ink/lead that you have to use so it also means that you use extra ink/lead to put the line under the equation… (so if it’s an open circle it is just the normal equation signs: < > ) And then if you put x in the front, your equality sign will point in whichever direction the arrow is pointing
21.) x < -2 22.) x < 5 (underline the <) 23.) x > -5 24.) x > 5 (underline the >) 25.) x > -2 26.) x > -5 (underline the >) 27.) x < 1 (underline the <) 28.) x > 1 (underline the >)
