Answer:
x = -5; y = 4, z = 1
Step-by-step explanation:
Given the row echelon form as:
This matrix can be represented as:
Therefore:
z = 1
y - z = 3;
y = 3 + z = 3 + 1 = 4.
Hence, y = 4
x + 4z = - 1;
x = -1 - 4z = -1 - 4(1) = -5
x = -5
The equation should be: Rent = 80 + 0.75 * Miles, then the graph looks like:
