What would the following system of equations look like in augmented matrix form?
Nesterboy [21]
Transforming equation systems into matrix form is fairly simple:
each column represents a variable, and each line represents an equation.
So in the first column, the NUMBERS MULTIPLYING by the X variables are put, in the second one the ones multiplying by Y, etc. The constants go after the vertical line, the last column
so we have:
\left \{ {{x+y=5} \atop {3x-y=-1}} =\{ {{1x+1y=5} \atop {3x+(-1)y=-1}}\right
So in a matrix, it will be the one on the picture

The side lengths of a triangle are 12, 19, and x units.
shepuryov [24]

Answer:

7<x<31

Step-by-step explanation:

The third side of any triangle must be more than the difference between the other two sides.

x>19-12

x>7 (or) 7<x

The third side of any triangle must be less than the sum of the other two sides.

x<19+12

x<31 (or) 31>x

Put them together.

7<x<31 (or) 31>x>7
