Answer:
![\frac{72-\sqrt{323} }{90}](https://tex.z-dn.net/?f=%5Cfrac%7B72-%5Csqrt%7B323%7D%20%7D%7B90%7D)
Step-by-step explanation:
Answer:
x=y-6
Step-by-step explanation:
First, flip the equation.
x+6=y
Finally, add -6 to both sides.
x+6+−6=y+−6
x=y−6
![a_{1,3} = 9](https://tex.z-dn.net/?f=a_%7B1%2C3%7D%20%3D%209)
Step-by-step explanation:
The elements of matrices are represented in the form
![a_{r,c}](https://tex.z-dn.net/?f=a_%7Br%2Cc%7D)
Here r is the row number and c is the column number.
Given matrix is:
![A = \left[\begin{array}{ccc}3&6&9\\2&4&8\end{array}\right]](https://tex.z-dn.net/?f=A%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D3%266%269%5C%5C2%264%268%5Cend%7Barray%7D%5Cright%5D)
The elements of matrix will be represented by a_{r,c}
We have to find ![a_{1,3}](https://tex.z-dn.net/?f=a_%7B1%2C3%7D)
Which means that the first row and third column.
The first row is: 3 6 9 and the element in third column is: 9
So,
![a_{1,3} = 9](https://tex.z-dn.net/?f=a_%7B1%2C3%7D%20%3D%209)

Answer:
![y=-\frac{2}{5} -1](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B2%7D%7B5%7D%20-1)
Step-by-step explanation:
So first thing is that slope intercept form is setup like this
y=mx+b
m=slope
b=y intercept
the slope is change in y over change in x
as y goes down 2 x goes up 5
so the slope is -2/5
the y intercept is at (0,-1) so the y intercept is -1
therefore the answer is
![y=-\frac{2}{5} -1](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B2%7D%7B5%7D%20-1)
have a great day :)
