When the given line is in standard form or general form (as here), the desired line can be found by replacing the constant by zero, and then translating the line to the given point.

The starting point for your solution can be
  7(x-7) - 5(y-9) = 0

In general form, this is
  7x - 5y - 4 = 0

In point-slope form, this is
  y - 9 = (7/5)(x - 7)

Jeff decided to purchase a house, his mortage is a 30-year loan at 4.1 % compounded monthly. The final purchase price was $150,0
vredina [299]

Answer:

  $711.23

Step-by-step explanation:

We assume the entire closing cost went to reducing the principal of the loan. Then the amount borrowed was $147,192.

<h3>Monthly payment</h3>

The amortization formula tells you the monthly payment.

  A = P(r/12)/(1 -(1 +r/12)^(-12t))

P is the principal, r is the annual rate, and t is the number of years.

The monthly payment is ...

  A = $147,192(0.041/12)/(1 -(1 +0.041/12)^-360) ≈ $711.23

Jeff's monthly payment is $711.23.

What is the arithmetic sequence in this problem . help plz
adell [148]

Answer:

<u>a(n)=80*(9/10)^(n-1)</u>

Step-by-step explanation:

I think u r confused

this sequence is geometric not arithmetic

HOw we know that ??

when we get a common difference  <u>that must Be equal  </u>

d=72-80=-8  not equal to  d=64.8-72=-7.2

So it is not arithmetic

but when we get the common ratio that also must <u>be equal </u>

r=72/80=9/10 equal to   r=64.8/72=9/10

So it is geometric

By using this equation:

a(n)=a*r^(n-1)

and we have <u>a=80 , r=9/10</u>

Then       <u>a(n)=80*(9/10)^(n-1)</u>

<em>I really hope this helps <3</em>
