State when the following equations and inequalities will be true and when they will be false.

1 answer:

6 0

' 36 = 9k ' is not an inequality. It's an equality, usually called an equation.

It's true whenever 'k' is 4, and false at any other time.

(You can determine that simply by dividing each side of the equation by 9.)

Maggie has $14,100 to invest, and wishes to gain $4,000 in interest over the next eight years. Approximately what is the minimum

Simple interest doesn't compound, so we just find the interest she needs by dividing 4,000 by 8, and then divide that number by her principal to find the rate of interest.

4,000 ÷ 8 = 500
She needs 500 dollars per year in interest.

800 ÷ 14,100 = .0355 = 3.55%

Answer is B

3 0
