Answer:
= - 1.5n - 6
Step-by-step explanation:
Given that the sequence is arithmetic with n th term ( explicit formula
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 7.5 and d = - 9 - (- 7.5) = - 9 + 7.5 = - 1.5
= - 7.5 - 1.5(n - 1) = - 7.5 - 1.5n + 1.5 = - 1.5n - 6
Step-by-step explanation:

Answer:
x = 1, x = -1
Step-by-step explanation:
-4x² = -4
x² = 1
x = 
x = ±1
Yes it will. A 2 quart pitcher is equal to 8 cups, and since 1/4 and 1/3 are less it can still hold it.
Answer:
x/3= $12.85
Step-by-step explanation:
