Answer:
A = $ 2,120.00

Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 3%/100 = 0.03 per year,
then, solving our equation

A = 2000(1 + (0.03 × 2)) = 2120 
A = $ 2,120.00

The total amount accrued, principal plus interest,
from simple interest on a principal of $ 2,000.00
at a rate of 3% per year
for 2 years is $ 2,120.00.

Solve the system of equations by elimination. <br><br> 2x + 2y = -2<br><br> 3x - 2y = 12
valkas [14]

Answer:

Step-by-step explanation:

2x + 2y = -2

3x - 2y = 12

5x = 10

x = 2

2(2) + 2y = -2

4 + 2y = -2

2y = -6

y = -3

(2, -3)

Answer:

3x - y + \frac{- 5x^2y}{3x^3 + 2x^2y - xy^2}

Step-by-step explanation:

Hooboy okay here we go.

1.) Rewrite the equation in the classic division method

3x³ + 2x²y - xy² \sqrt{9x^4 + 3x^3y - 5x^2y^2 + xy^3}

2.) Divide using normal division rules, but it's super hard now 'cause there are letters involved. Basically, what can you multiply 3x³ by to get 9x⁴? 3x. So 3x is your first number. Then multiply everything else by 3x, and subtract

                                          3x

3x³ + 2x²y - xy² \sqrt{9x^4 + 3x^3y - 5x^2y^2 + xy^3}

                                       -(9x⁴ + 6x³y - 3x²y²)

                                      = 0     - 3x³y - 2x²y² - 5x²y + xy³

Now lets do that again, see what happens. 3x³ times -y should get -3x³y

                                          3x - y

3x³ + 2x²y - xy² \sqrt{9x^4 + 3x^3y - 5x^2y^2 + xy^3}

                                      - (9x⁴ + 6x³y - 3x²y²)

                                      = 0     - 3x³y - 2x²y² - 5x²y + xy³

                                            - ( - 3x³y - 2x²y²            + xy³)

                                               =   0    + 0       - 5x²y  + 0

So! From this information, we can know that the answer is 3x-y with a remainder of - 5x²y. How it's written is shown above, in "Answer"

Solve for x:<br> 5(2x - 4) = 10
olga55 [171]

Answer:

x = 3

Step-by-step explanation:

First you want to divide both sides by 5 to get 2x-4 = 2.

Afterwards, you add 4 to both sides of the equation. 2x = 6

Divide both sides by 2. x = 3
