Get the b all alone on one side of the inequality. To do this, we can divide both sides by 5.
5b / 5 ≤ -15 / 5
b ≤ -3
So, that means b has to be less than or equal to -3.
In interval notation it would look like [-3, -∞)
In a set builder notation: {x | x ∈ R, x ≤ -3}
Which is read as the set of all x, such that, x is a member of the real numbers and x is less than or equal to -3.

Answer:
C) $10,000 invested at 6.7% compounded quarterly over 7 years yields the greater return.
Step-by-step explanation:
-We determine the effective interest rate in both scenarios and use it to calculate the investment's value after 7 years.
#Given n=7yrs, P=$10,000 and i=6.6% compounded monthly:

#Given n=7rs, P=10000, i=6.7%

Hence, the investment has the largest value($15,921.75) when the interest rate is compounded quarterly.
