Answer:
Look below.
Step-by-step explanation:

Use a calculator.
Answer: x < -3
Step-by-step explanation:
-3*x-4-(5)>0
Let

where we assume |r| < 1. Multiplying on both sides by r gives

and subtracting this from
gives

As n → ∞, the exponential term will converge to 0, and the partial sums
will converge to

Now, we're given


We must have |r| < 1 since both sums converge, so


Solving for r by substitution, we have


Recalling the difference of squares identity, we have

We've already confirmed r ≠ 1, so we can simplify this to

It follows that

and so the sum we want is

which doesn't appear to be either of the given answer choices. Are you sure there isn't a typo somewhere?

Answer:
0.6
Step-by-step explanation:
9 is the numerator and 15 is the denominator
divide 9 ÷ 15
which is 0.6
