Answer:

x = -1 or

x = -7

Step-by-step explanation:

Given DAB and BCD are similar :

2x^2 + 7 = x^2 - 8x make the left side of equation 0 by exporting all terms to right side

2x^2 - x^2 + 8x + 7 = 0 add like terms

x^2 + 8x + 7 = 0

(x + 1) * (x + 7) = 0 in this case x is either -1 or -7

An investor obtains a balloon mortgage with the terms shown below.

Flauer [41]

9514 1404 393

Answer:

a. $3,455.20

Step-by-step explanation:

The monthly payment is given by the amortization formula:

A = P(r/12)/(1 -(1 +r/12)^(-12t))

for loan amount P at annual rate r for t years.

For this mortgage, we use P = $530,000, r = 0.068, t = 30.

A = $530,000(0.068/12)/(1 -(1 +0.068/12)^(-360)) ≈ $3,455.20

The monthly payment is $3,455.20.

_____

<em>Additional comment</em>

In 7 years, the balloon payment will be $481,559.91.

What is the fourth term of an arithmetic sequence whose first term is 23 and whose seventh term is 5?

mixas84 [53]

We have that the fourth term of an arithmetic sequence is

a_4=14

Option C

From the question we are told

What is the fourth term of an arithmetic sequence whose first term is 23 and whose seventh term is 5?

A) 78

B) 32

C) 14

(Explain your work)

Generally the equation for the arithmetic sequence is mathematically given as

$a_4=a_1+(n-1)d$

Therefore

For seventh term

$5=23+(6)d\\\\d=5-23/(6)\\\\d=-3$

Therefore

For Fourth term

$a_4=23+(3*(-3))$

a_4=14

Simplify (7x+42)/(x^2+13x+42)

Colt1911 [192]

$\frac{7x+42}{x^2+13x+42}= \frac{7(x+6)}{x^2+7x+6x+42}= \frac{7(x+6)}{x(x+7)+6(x+7)}= \frac{7(x+6)}{(x+6)(x+7)}= \frac{7}{x+7}$
