Answer: Choice B
=====================================
Explanation:
The given matrix is
![\left[\begin{array}{cc|c}1&5&11\\4&-6&-3\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7Cc%7D1%265%2611%5C%5C4%26-6%26-3%5Cend%7Barray%7D%5Cright%5D)
The numbers to the right of the vertical bar represent the values on the right hand side of each equation in the final answer.
The numbers to the left of the bar represent the x and y coefficients of the equations. The first number of any given row is the x coefficient. The second number is the y coefficient.
For instance, the first row has 
to indicate the x coefficient is 1, and the y coefficient is 5. We end up with 1x+5y or simply x+5y. Putting everything together, the first equation would be x+5y = 11
Through similar steps, the second equation is 4x-6y = -3
Answer:
C) y = 2x - 3 and y = -2x - 1.

Answer:
Answer:
Domain = {x /x ≥ -7}
Step-by-step explanation:
The given function y =
Inside the square, negative will not come.
First let's find the domain. x + 7 must be greater than or equal to 0.
x + 7 ≥ 0
Solving x, we get
x ≥ -7
Domain = {x /x ≥ -7}
