Answer:

$D.....is\: the \: equivalent \: system$

Step-by-step explanation:

$if \to 4x + 5y = 3 \\ if \to 2x + 3y = 1 \\then \\ 2 \times \: 4x + 5y = 3 \\ 4 \times 2x + 3y = 1 \\ 10y - 12y = 6 - 4 \\ - 2y = 2 \\ \boxed{ y = - 1} \\ 4x + 5y = 3 \\ 4x +5( - 1) = 3 \\ 4x - 5 = 3 \\ 4x = 3 + 5 \\ 4x = 8 \\ \boxed{x = 2} \\ hence \: the \: equivalent \: system \: is \to D \\$

How long will it take for an investment to triple if it is compounded continuously at 12%

myrzilka [38]

Answer:

9.694 years

Step-by-step explanation:

Let the investment is $P.

So, we are asked to determine the time it will grow to triple with the compound interest rate of 12%.

Let the time is y years.

So, from the formula of compound interest we can write

$3P = P(1 + \frac{12}{100} )^{y}$

⇒ $(1 + \frac{12}{100} )^{y} = 3$

⇒ $(1.12)^{y} = 3$

Now, taking log both sides we get,

y log 1.12 = log 3 {Since, $\log a^{b} = b \log a$ }

⇒ 0.04922y = 0.477712

⇒ y = 9.694 years (Answer)
