<u>Answer:</u> $42546.9 will be the earning in 4 years.

<u>Step-by-step explanation:</u>

The equation for compound interest follows:

A=P(1+\frac{r}{100})^n

where,

A = total amount

P = Principle amount

r =  rate of interest

n = number of years

We are given:

Earnings earned per month = $3250

Earnings earned per year = ($3250 × 12) = $39000

The values become:

P=\$39000\\r=2.2\%\\n=4yrs

Putting values in above equation, we get:

A=39000(1+\frac{2.2}{100})^4\\\\A=\$ 42546.9

Hence, $42546.9 will be the earning in 4 years.

Solve the simultaneous equation <br> 2x - 5y = 9<br> 3x + 4y = 2
lianna [129]

Answer:

x = 2, y = -1.

Step-by-step explanation:

2x - 5y = 9

3x + 4y = 2

Multiply first equation by -3 and the second by 2:

-6x + 15y = -27

6x + 8y = 4            Adding the 2 equations:

23y = -23

y = -1.

Now substitute this value for y in the first equation:

2x - 5(-1) = 9

2x = 9 +5(-1)

2x = 9 - 5

2x = 4

x = 2.

Answer:

  f(g(x)) = 2/(x^2 +4x)

Step-by-step explanation:

  (f\circ g)(x)=f(g(x))\\\\(f\circ g)(x)=f(x+2)=\dfrac{2}{(x+2)^2-4}\\\\(f\circ g)(x)=\dfrac{2}{x^2+4x+4-4}\\\\\boxed{(f\circ g)(x)=\dfrac{2}{x^2+4x}}
