The simplified expression of -(-7y+12) is (7y - 12). In simplifying expressions, we  just need to multiply the variable inside the parenthesis by the variable outside. In this case, negative sign outside the parenthesis is not just a negative but rather it means that it is negative 1 or -1. It is always assumed that when there is no numeric value on the sign the value of which is one.

Suppose you invest $16000 at 9% interest and that it is compounded daily. How much will you have in 8 years?
kramer

Answer:

The amount after 8 years is $ 16,031.579

Step-by-step explanation:

Given as :

The Principal invested = $ 16000

The rate of interest compounded daily = 9 %

The time period = 8 years

Let The amount after 8 years = $ A

<u>From Compounded method </u>

Amount = Principal invested × (1+\dfrac{\textrm Rate}{365\times 100})^{365\times \textrm Time}

Or, Amount = 16000 × (1+\dfrac{\textrm 9}{365\times 100})^{365\times \textrm 8}

Or, Amount = 16000 × (1.0002465)^{8}

∴  Amount = $ 16,031.579

Hence The amount after 8 years is $ 16,031.579   Answer

Put these in order below are exactly divisible by 9?<br><br> 119 702 432 641 372
KiRa [710]
119 ÷ 9 = 13 2/9
702 ÷ 9 = 78
432 ÷ 9 = 48
641 ÷ 9 = 71 2/9
372 ÷ 9 = 41 3/9 ⇒ 41 1/3

702 and 432 are divisible by 9. The rest are not.
