The lines are
i) y=-x+6
ii) y=2x-3
The solution of the system of equations is found by equalizing the 2 equations:
-x+6=2x-3
-2x-x=-6-3
-3x=-9
x=-9/(-3)=3
substitute x=3 in either i) or ii):
i) y=-3+6=3
ii) y=2(3)-3=6-3=3
(the result is the same, so checking one is enough)
This means that the point (3, 3) is a point which is in both lines, so a solution to the system.
In graphs, this means that the lines intersect at (3, 3) ONLY
Answer: The graph where the lines intersect at (3, 3)
Answer:
359
Step-by-step explanation:
5-2+5-54-3+405+12-9=359
It is the first number line :)
3.75, 3.9, 4.256, 4.258, 4.5
Answer: 133
Step-by-step explanation:
171 for 9 hours
171/9 equals 19
So 19 dollars per hour
7 hours times 19 dollars per hour equals 133
