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.
D -9 because it has a -3 and its going to be the same - sign
For this case we have the following equation:
Density = mass / volume
If the volume is the same, then the object with the greatest weight will be the one with the highest density.
You must know the type of way to know the value of the density.
Answer:
The weight of the blocks will depend on the density if the volume is the same.
Answer:
X=4
Step-by-step explanation:
2X - 10 = -2
2X = 8
X = 8/2
X = 4
Best regards
