The given system of equations has infinitely many solutions.

Important information:

  • 2x-9y=-5
  • 4x-6y=2
<h3>System of equations:</h3>

Two equations a_1x+b_1y+c_1=0 and a_2x+b_2y+c_2=0 has infinitely many

solutions if \frac{a_1}{a_2} =\frac{b_1}{b_2} =\frac{c_1}{c_2}.

In the given equations, a_1=20,b_1=-9,c_1=-5,a_2=4,b_2=-6,c_2=2.

\frac{2}{4} =\frac{-9}{-6} =\frac{-5}{2} =5

\frac{a_1}{a_2} =\frac{b_1}{b_2} =\frac{c_1}{c_2}, therefore the given system of equationsinfinitely many solutions.

1) The accumulated amount after six years and the total interest that Trevor will receive if the interest rate is 4.5% per annum simple interest after 6 years are <u>R25,400</u> and <u>R5,400</u> respectively.

2) The accumulated amount after six years and the total interest that Trevor will receive if the interest rate is 4.5% per annum compound interest after 6 years are<u> R26,045.20</u> and <u>R6,045.20</u> respectively.

<h3>Data and Calculations:</h3><h3>Simple Interest:</h3>

Principal = R20,000

Investment period = 6 years

Interest rate = 4.5%

Simple interest for 6 years = R5,400 ($20,000 x 6 x 4.5%)

Principal + Interest = R25,400 (R20,000 + R5,400)

<h3>Compound Interest:</h3>

Principal = R20,000

Investment period = 6 years

Interest rate = 4.5%

N (# of periods) = 6 years

I/Y (Interest per year) = 4.5%

PV (Present Value) = R20,000

PMT (Periodic Payment) = R0

<u>Results</u>:

FV = R26,045.20

Total Interest = R6,045.2
