Answer:
$3087.35
Step-by-step explanation:
<u>Compound interest formula</u>
where:
- A = final amount
- P = principal
- r = interest rate (in decimal form)
- n = number of times interest applied per time period
- t = number of time periods elapsed
Given:
- P = $1500
- r = 6.2% = 0.062
- n = 1
- t = 12 years
Substituting given values into the equation and solving for A:
Answer:
exponential
Step-by-step explanation:
it does not form a straight line
Given:
The objective is to find the slope of the straight line.
Explanation:
The general equation to find the slope is,
Let's consider two coordinates from the graph.
On plugging the values in the equation of slope,
Hence, the slope of the straight line is -5.

Answer: (x,y) = (4,1)</h3>
In other words, x = 4 and y = 1
==============================================
Explanation:
Add the equations straight down.
- The x terms add to 3x because 2x+x = 3x
- The y terms go away when you add them since -y+y = 0y = 0
- The terms on the right hand sides add to 7+5 = 12
After those three sets of adding terms, we end up with 3x = 12. This solves to x = 4 when you divide both sides by 3.
Use this x value to find y.
2x-y = 7
2(4)-y = 7
8-y = 7
-y = 7-8
-y = -1
y = 1
or
x+y = 5
4+y = 5
y = 5-4
y = 1
Your best best is probably to use the second equation, but it doesn't hurt to have practice with both equations. Getting the same y value helps confirm we have the correct x value.
Therefore, the solution is the ordered pair (x,y) = (4,1). Meaning that x = 4 and y = 1 pair up together.
Visual confirmation can be done by using a graphing tool like Desmos. The two lines intersect at (4, 1). See below.
