f(x) + g(x) = 3x³ + 8x - 24
that is 3x³ + 7x - 26 + x + 2 = 3x³ + 8x - 24
Answer:
b
Step-by-step explanation:
Simplified expression for total amount spent is 10(2.05 + m)
Step-by-step explanation:
- Step 1: Write expression for expense on joining cooking club for m months.
Expense = 8.50 + 6.25 × m
- Step 2: Write expression for expense on joining movie club for m months.
Expense = 12 + 3.75 × m
- Step 3: Calculate the total amount spent on both clubs
Total Amount = 8.50 + 6.25m + 12 + 3.75m = 20.5 + 10m = 10(2.05 + m)
Answer:
This is a 25% decrease
Step-by-step explanation:
percent change = (old - new)/old * 100 %
The new price is 15
The old price is 20
Since the new price is less than the old price, it is a decrease
percent change = (20-15)/20 * 100 %
= 5/20 * 100%
=.25 * 100%
= 25%
This is a 25% decrease
