If $26 represents the cost of  the 5 used CDs, than your formula would be "26+4x" ,x being the amount of extra CDs you purchase.


The number CDs minus 5 is our x value, because the first 5 are the used CDs bundled into the $26 group.

26+4(6-5)
26+4(1)
26+4
30

6 CDs would cost $30

Solve each quadratic equation by factoring and check
max2010maxim [7]

hello : <span>
<span>the discriminat of each quadratic equation : ax²+bx+c=0 ....(a ≠ 0) is :
Δ = b² -4ac
1 )  Δ > 0  the equation has two reals solutions : x1,2 =  (-b±√Δ)/2a</span></span>

factoring :

<span>ax²+bx+c = a(x-x1)(x-x2)
2 ) Δ = 0 : one solution : x1 = x2 = -b/2a</span>

factoring  : 

<span>ax²+bx+c = a(x-x1)²
3 ) Δ < 0 : no reals solutions... no </span>

The Henley's took out a loan for $195,000 to purchase a home. At a 4.3% interest rate
ella [17]

Interest paid after 30 years is $494,546.99.

Solution:

Principal (P) = $195,000

Interest rate (r) = 4.3%

Time (t) = 30 years

n = number of times interest calculated per year

n = 1

Compound interest formula:

$A=P\left(1+\frac{r}{n}\right)^{n t}

where A is the final amount

$A=195000\left(1+\frac{4.3\%}{1}\right)^{1\times 30}

$A=195000\left(1+\frac{4.3}{100}\right)^{30}

$A=195000\left(\frac{100+4.3}{100}\right)^{30}

$A=195000\left(\frac{104.3}{100}\right)^{30}

A = 689546.99

Interest = Amount  - Principal

             = 689546.99 - 195000

             = 494546.99

Interest paid after 30 years is $494,546.99.

ddd [48]

Step-by-step explanation:

Dod you mean

=  \frac{ {n}^{5} }{ {n}^{ - 2} }  \times  \frac{ {n}^{2 - 6} }{ {n}^{8} }

=  {n}^{5 - ( - 2)}  \times  {n}^{2 - 6 - 8}

=  {n}^{7}  \times  {n}^{ - 12}

=  {n}^{7 + ( - 12)}

=  {n}^{ - 5}  =  \frac{1}{ {n}^{5} }
