You need to have $20,000 for a down payment on a house 6 in years. If you can earn an annual interest rate of 4.2 percent, how m
Alexxandr [17]

Answer: you have to deposit $15625 today

Step-by-step explanation:

Assuming the interest is compounded annually. We would apply the formula for determining compound interest which is expressed as

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

Where

A = total amount in the account at the end of t years

r represents the interest rate.

n represents the periodic interval at which it was compounded.

P represents the principal or initial amount deposited

From the information given,

A = $20000

r = 4.2% = 4.2/100 = 0.042

n = 1 because it was compounded once in a year.

t = 6 years

Therefore,.

20000 = P(1 + 0.042/1)^1 × 6

20000 = P(1.042)^6

20000 = 1.28P

P = 20000/1.28

P = $15625

Solve the system of equations x - 2y = – 7 and -3x – 2y = 29 by combining the<br> equations.
Ksivusya [100]

Answer:

x = - 9, y = -1

Step-by-step explanation:

<em>Given:</em>

<em />\begin{bmatrix}x-2y=-7\\ -3x-2y=29\end{bmatrix}

Solve:

\mathrm{Substitute\:}x=-7+2y

\begin{bmatrix}-3\left(-7+2y\right)-2y=29\end{bmatrix}

\begin{bmatrix}21-8y=29\end{bmatrix}

\mathrm{For\:}x=-7+2y

\mathrm{Substitute\:}y=-1

x=-7+2\left(-1\right)

x=-9

\mathrm{Thus, Answer:x=-9,\:y=-1}
