1.) Let's say that the circle on the graph below represents x. The arrow is pointing to all the numbers greater than x, which happens to be on -2. If it points right, this means that x can equal to any number greater than -2. So your answer is x > -2.
2.) For inequalities such as these, you can simplify just like what you do for normal equations. Let's isolate x.

Answer:
(B)
Step-by-step explanation:
PRINCIPAL AMOUNT(p) = $400
RATE (r)= 250% = 2.5
INTEREST = $80
t = time (in days) = t/365
By using the formula,
r =
2.5 =
t =
t = 29.2
t = 29 days (approx)
Hence option (B) is correct.
