Answer:

Step-by-step explanation:



The equation for annual interest is A = P(1 + r)^t. We can plug in the known information and get A = 16,000(1 + (0.06))^3.5. Next, we can simplify this equation to A = 16,000(1.06)^3.5. Finally, we raise 1.06 to the power of 3.5 and multiply that by 16,000 and get an answer of $19,619.62.

<u>ANSWER</u>
A. (4,12)
<u>EXPLANATION</u>
The equations are:

and

To eliminate a variable we make the coefficients of that variable the same in both equations.
It is easier to eliminate x.
We multiply the first equation by 2 to get:

We add equations (2) and (3).


Divide both sides by 23


Put x=4 into equation (1).






The solution is (4,12)
Answer:
a = -12
Remember that when a variable is times with a number, you <u>divide</u> the number on both sides.
When a variable is divided by a number, you <u>multiply</u> the number on both sides.
