X+y+z=11, x-y+z=5, x-z=y+1 and solve it by any of the methods: isolation, elimination or determinants. isolation (or back substitution, would be for instance: z = 11-x-y, z=5-x+y, z = x-y-1 and then impose z=z:
11-x-y=5-x+y,
11-x-y=x-y-1,
The first takes you to: 6=2y or y=3, then the second to 12=2x or x=6, so that:
x=6, y=3, z=2.
You can see that it checks out
Answer:
The starting time.
Step-by-step explanation:
Since the graph represents Quinten’s distance from the start line as he runs a cross country race. And the x-axis represents the time, in hours, and the y-axis represents distance, in miles.
If the intercept is at y axis, it will represent the starting position. That is, the starting distance in miles.
But since the intercept is at x axis, the x-intercept represents the starting time in this situation.
The x-intercept will represent the starting time if the slope of the graph is positive, and represents the ending time if the slope of the graph is negative.
$595 - 20% = $476
