Answer:
5. B 4, 24, 44, 64, 84, 104, 124
6. F -9 < x (less than or equal to) -2
7. G. All Real Numbers
Explanation:
5. The 4 is always their, so the answer must be multiples of 20 + 4. There are only 6 weights so it can't go over 124
6. The -9 is an open circle and therefor <, the -2 is a closed circle and therefor less than or equal to.
7. There are no X inputs that would make the function have an imaginary output
