3x +(x-2)=10 you substitute the y= for the y
Add the x 4x -2 =10
Move the -2 to the other side 4x =12
x= 3
Now substitute the x= for the x in the other equation y= 3-2
y=1
Your answer is (3,1)
Hope this helps❗️

3x+(x-2)=10
4x=12
x=12/4=3

y=x-2=3-2=1

so, x=3 and y=1

STatiana [176]

Answer:

The answer to your question is 8649 persons

Step-by-step explanation:

Data

Equation              y = 11.89x - 15345.2

Year = x = 2018

Process

1.- Just substitute x in the equation

                            y = 11.89 (2018) - 15345.2

2.- Multiply 11.89 by 2018

                            y = 23994.02 - 15345.2

3.- Subtract to find x

                           y = 8648.82

4.- Conclusion

There was 8649 persons in 2018.

Two banks offer compound intereston your investment while you deposit with them. Bank A calculates compound interest annuallyand
sladkih [1.3K]

Answer:

Bank B because the more often you compound interest, the more interest you earn.

Step-by-step explanation:

Bank A compounds the interest once a year.

Bank B compounds the interest twice a year.

Let's create an example of two investments of the same amount of money, the same interest rate, and the same time. The only difference will be the number of times the interest is compounded per year.

Compound interest formula:

A = P(1 + \dfrac{r}{n})^{nt}

where

A = future value

P = principal invested

r = interest rate

t = number of years

n = number of times interested is compounded in 1 year

Example:

P = $1000

r = 5%

t = 5 years

Bank A: n = 1

Bank B: n = 2

Bank A:

A = $1000(1 + \dfrac{0.05}{1})^{1 \times 5} = $1276.28

Bank B:

A = $1000(1 + \dfrac{0.05}{2})^{2 \times 5} = $1280.08

Bank A's investment is worth $1276.28 after 5 years, but Bank B's investment is worth $1280.08 after the same 5 years. Compounding twice per year instead of only once per year earns more interest.
