X + 2y = 13 -x + y = 5

Mathematics
1 answer:
wlad13 [49]3 years ago
7 0

Answer:

x = 1; y = 6

Step-by-step explanation:

x + 2y = 13

-x + y = 5

Add the equations to eliminate x.

3y = 18

Divide both sides by 3.

y = 6

Now substitute y with 6 in the first equation.

x + 2(6) = 13

x + 12 = 13

Subtract 12 from both sides.

x = 1

Answer: x = 1; y = 6

What is the total amount for an investment of $1000 invested at 7.25% for 15 years and compound continuously?
Iteru [2.4K]

Answer:

\$2,966.85  

Step-by-step explanation:

we know that

The formula to calculate continuously compounded interest is equal to

A=P(e)^{rt}  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest in decimal  

t is Number of Time Periods  

e is the mathematical constant number

we have  

t=15\ years\\ P=\$1,000\\ r=0.0725  

substitute in the formula above  

A=\$1,000(e)^{0.0725*15}=\$2,966.85
