Answer:

see explanation

Step-by-step explanation:

Given the 2 equations

x + 2y = 10 → (1)

2y² - 7y + x = 0 → (2)

Rearrange (1) expressing x in terms of y by subtracting 2y from both sides

x = 10 - 2y → (3)

Substitute x = 10 - 2y into (2)

2y² - 7y + 10 - 2y = 0

2y² - 9y + 10 = 0 ← in standard form

(y - 2)(2y - 5) = 0 ← in factored form

Equate each factor to zero and solve for y

y - 2 = 0 ⇒ y = 2

2y - 5 = 0 ⇒ 2y = 5 ⇒ y = \frac{5}{2}

Substitute these values into (3) for corresponding values of x

y = 2 → x = 10 - 4 = 6 ⇒ (6, 2 ) → B

y = \frac{5}{2} → x = 10 - 5 = 5 ⇒ (5, \frac{5}{2} ) → A

Chris invests $20,000 into a savings account that accrues 5.2% interest compounded semiannually. What is the balance of Chris' a
il63 [147K]

The amount to be paid after 3 years is  $23,329.97.

<h3>What is Compound Interest?</h3>

In order to compute compound interest, multiply the principle of the original loan by the annual interest rate multiplied by the number of compound periods minus one. You will then be left with the principal amount of the loan plus compound interest.

Given:

P= 20,000

r= 5.2%

t= 3 years

r = R/100

r = 5.2/100

r = 0.052 rate per year,

Now, solve for A

A = P(1 + r/n)^{nt

A = 20,000.00(1 + 0.052/2)^{(2)(3)

A = 20,000.00(1 + 0.026)^(6)

A = $23,329.97
