Final answer:
To simplify the expression -1 - 10v + 6v - 9, combine like terms to get -4v (combination of variable terms) and -10 (sum of constants), resulting in the simplified expression -4v - 10.
Step-by-step explanation:
The student seeks to simplify the algebraic expression -1 - 10v + 6v - 9. To simplify, we must combine like terms, which in this case are the variable terms -10v and +6v and the constant terms -1 and -9. When we combine these like terms, we add the coefficients of the variable terms and sum the constants: -10v + 6v = -4v and -1 - 9 = -10. Therefore, the simplified expression is -4v - 10.
