The equation is y= -2x + 1
Using a Laplace expansion along the first column, we have

The determinant of a 2x2 matrix is trivial,

So we have

Answer:
-1
Step-by-step explanation:
Plug in given values
-4x + 5y + 6z
-4(-2) + 5(3) + 6(-4)
8 + 15 -24
23-24
-1
To find the range of a set, subtract the largest number and the smallest number. Those numbers, in this set, are 63 and 34.
63-34=29
So the range is 29
