alleryWhich one of these is an expression, not a formula?
A8x − 5 ≥ 3
B8x − 5
Cx + 2 = 7
D3 < 9
Answer & Solution
Correct answer: B. 8x − 5
1. A formula makes a statement, usually with =, < or ≥.
2. 8x − 5 has no relation sign, so it only names a quantity.
3. The other three each state an equality or inequality.
