Answer:
A. 1.06
B. $6,784
Step-by-step explanation:
I = A - P = $384.00
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 6%/100 = 0.06 per year.
Solving our equation:
A = 6400(1 + (0.06 × 1)) = 6784
A = $6,784.00
The total amount accrued, principal plus interest, from simple interest on a principal of $6,400.00 at a rate of 6% per year for 1 year is $6,784.00.

Step-by-step explanation:
<u>Step 1: Define Systems</u>
y = -2x + 9
y = 3x + 9
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>: 3x + 9 = -2x + 9
- [Addition Property of Equality] Add 2x on both sides: 5x + 9 = 9
- [Subtraction Property of Equality] Subtract 9 on both sides: 5x = 0
- [Division Property of Equality] Divide 5 on both sides: x = 0
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define equation: y = -2x + 9
- Substitute in <em>x</em>: y = -2(0) + 9
- Multiply: y = 0 + 9
- Add: y = 9
The answer is 0 because when you plug in the 3 and the 8 into the equation and do order of operations you will get 0.
