The matrix that represents this system takes the x coordinates and puts them in a column and then the y coordinates and puts them in a column and then the solutions in another. Like this: ![\left[\begin{array}{ccc}7&8\\-3&9\\\end{array}\right] =\left[\begin{array}{ccc}28\\-24\end{array}\right]](https://tex.z-dn.net/?f=%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D7%268%5C%5C-3%269%5C%5C%5Cend%7Barray%7D%5Cright%5D%20%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D28%5C%5C-24%5Cend%7Barray%7D%5Cright%5D%20%20)
. That's what your matrix would look like.
29 and 12! 29 + 12 comes out to 41 and 29 - 12 comes out to 17. I hope this helps!!
Hi, I think the answer should be $4.26
7.25% × $24 = $1.74
$24 +1.74 = $25.74
Change is the difference between the amount tendered and this total amount:
$30.00 -25.74 = $4.26
Answer:
C: The speed increases from A to F
Step-by-step explanation:
Check each node A to F including A and F.
B is higher than A, C is higher than B, ...
This is true for all of them, so it is increasing.
