Final answer:
To find the expressions that are equivalent to Negative 9 (two-thirds x + 1), distribute the negative 9 to both terms.
Step-by-step explanation:
A mathematical expression is a combination of numbers, variables, and operations, often written in symbolic form. Examples include equations, inequalities, and formulas. Expressions are fundamental in representing mathematical relationships and are manipulated to solve problems in algebra, calculus, and other branches of mathematics.
To find the expressions that are equivalent to Negative 9 (two-thirds x + 1), we need to distribute the negative 9 to both terms inside the parentheses:
Equivalent expressions:
- Negative 9 (two-thirds x) + 9 (1)
- Negative 9 (two-thirds x) - 9 (1)
- Negative 9 (two-thirds x) + 1
- –6x + 1
- –6x + 9
- –6x - 9
