Divide (12n^3+8n^2-6n)/2n^2

$\frac{12n^{3} + 8n^{2} - 6n}{2n^{2}} = \frac{12n^{3}}{2n^{2}} + \frac{8n^{2}}{2n^{2}} - \frac{6n}{2n^{2}} = 6n + 4 - \frac{3}{n}$

Answer:

for the first question

8² +7²=x²

64 +49=x²

x=√113

similarly for second

15²+18²=x²

225+324=x²

A dealer sells a certain type of chair and a table for $40. He also sells the same sort of table and a desk for $83 or a chair a

vesna_86 [32]

$Chair=x$

$Table=y$

$Desk=z$

$\begin{Bmatrix}x+y&=&40\\y+z&=&83\\x+z&=&77\end{matrix}$

keep the first row as normal, then in the other ones, we can isolate Y and X

$\begin{Bmatrix}x+y&=&40\\y&=&83-z\\x&=&77-z\end{matrix}$

now we can replace at first row...

$\begin{Bmatrix}(77-z)+(83-z)&=&40\\y&=&83-z\\x&=&77-z\end{matrix}$

$\begin{Bmatrix}160-2z&=&40\\y&=&83-z\\x&=&77-z\end{matrix}$

$\begin{Bmatrix}-2z&=&40-160\\y&=&83-z\\x&=&77-z\end{matrix}$

$\begin{Bmatrix}-2z&=&-120\\y&=&83-z\\x&=&77-z\end{matrix}$

$\begin{Bmatrix}z&=&60\\y&=&83-z\\x&=&77-z\end{matrix}$

now we can replace the Z to discovery the other value

$\begin{Bmatrix}z&=&60\\y&=&83-60\\x&=&77-60\end{matrix}$

$\boxed{\boxed{\boxed{\begin{Bmatrix}Chair&=&17\\Table&=&23\\Desk&=&60\end{matrix}}}}$

Find the slope: (12, 10), (12, 5)

Over [174]

Answer:

sorry about that v but to make it shorter the answer is undefined

Step-by-step explanation:

To calculate the slope (m) use the

The 2 points here are (12 ,10) and (12 ,5)

Division by 0 is undefined , hence slope is undefined.

This is, in fact, a line parallel to the y-axis and passing through all points in the plane with an x-coordinate equal to 12.

For this reason it's equation is x = 12

A 'quick' way to note when this situation occurs is to observe that the x-coordinates of the 2 given points are equal.
