Answer:
f(1) = 31.
Step-by-step explanation:
f(n + 1) = f(n) - 3
So f(4) = f(3) - 3
22 = f(3) - 3
f(3) = 22 + 3 = 25
so f(2) = 25 + 3 = 28
and f(1) = 28 + 3 = 31.
Answer:
223.38
Step-by-step explanation:
If you could prove that <em>all sides of the parallelogram </em><em>are congruent</em>, then you'd have proved it's a rhombus.
The answer is C) 7.
In function 1, there is no rate of change.
In function 2, there is a rate of change of 7.
This leaves 7 as the only possible answer.
