Answer:

Option D) is correct

That is x=2 , y=-5

Step-by-step explanation:

Given that the |A|=\left| \begin{array}{cc}4&-6\\ 8&-2\end{array}\right|, \left|A_x\right|=\left|\begin{array}{cc}38&-6\\ 28&-2\end{array}\right|, \left|A_y\right|=\left|\begin{array}{cc}4&38\\ 8&26\end{array}\right|

To find their determinants

|A|=\left| \begin{array}{cc}4&-6\\ 8&-2\end{array}\right|

=-8+48

=40

Therefore |A|=40

|A_x|=\left|\begin{array}{cc}38&-6\\ 28&-2\end{array}\right|

=-76+156

=80

Therefore |A_x|=80

|A_y|=\left|\begin{array}{cc}4&38\\ 8&26\end{array}\right|

=104-304

=-200

Therefore |A_y|=-200

To find the values of x and y:

x=\frac{|A_x|}{|A|}\ \textrm{and}\ y=\frac{|A_y|}{|A|}

x=\frac{80}{40} and y=\frac{-200}{40}

x=2 and y=-5

Option D) is correct

That is x=2 , y=-5

gogolik [260]

Answer:

x =  \frac{ - 24 \pm \sqrt{ - 288} }{4}  \\  =  \frac{ - 24 \pm \sqrt{ ( - 1) {(12)}^{2} (2)} }{4} \\  =   \frac{ - 24 \pm \sqrt{ - 1}  \sqrt{ {12}^{2} } \sqrt{2}  }{4} \\  =   \frac{ - 24 \pm i 12\sqrt{2}  }{4} \\  =-\frac{24}{4}\pm \frac{i12\sqrt{2}}{4}\\=  -  6  \pm \: i3 \sqrt{2}

A house is purchased for $375000 and has gained 12% for the last 5 years. What is it now ?
Ksenya-84 [330]

Answer:

  $420,000

Step-by-step explanation:

The added percentage can be turned into a multiplier to make the problem easier.

  value + 12%×value = value(1 +0.12) = 1.12×value

  1.12×$375,000 = $420,000

It is $420,000 now.
