Answer:
(x, y) = (1, -1)
Step-by-step explanation:
The augmented matrix of coefficients for these equations is ...
![\left[\begin{array}{cc|c}2&-5&7\\-2&4&-6\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7Cc%7D2%26-5%267%5C%5C-2%264%26-6%5Cend%7Barray%7D%5Cright%5D)
The row-reduction function of your calculator can find the solution to the system of equations. The result of using that function is ...
![\left[\begin{array}{cc|c}1&0&1\\0&1&-1\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7Cc%7D1%260%261%5C%5C0%261%26-1%5Cend%7Barray%7D%5Cright%5D)
This tells you the solution is (x, y) = (1, -1).

No, it is an irrational number because it does not terminate/end
Answer:
f=7x g=3 x=18
Step-by-step explanation:
Constant rate means it is linear so we don't have to worry about fluctuation.
change in y/ change in x=-18-(-25.2)/5-8=2.4 meters per second
