d. budget.
Answer: B. variable costs.
Step-by-step explanation:
1/2x - 3y = 8
(-15b - 7) - (-2b)
Answer:
13b + 7
Step-by-step explanation:
Combine like terms. (-15b - 7) - (-2b), add -15b to both sides, the equation then becomes (-7) - (13b). Swap the equation around to become (13b) - (-7), a subtraction sign and then a negative makes the negative a positive. The equation then becomes 13b + 7.
