Answer:
5.5 units
Step-by-step explanation:
I'm not 100% sure if this is right, since it could be 5 or 6, but since there is a slight diagonality to it, i would say 5.5 units.
I got 2.17 but I'm not sure that's right.
Answer:
(2/3, 13/3) (Exactly one solution)
Step-by-step explanation:
Write these equations in a column:
x+y=5
2x-y=-3
Note that we can eliminate y immediately by adding these two equations together. We get:
3x = 2, so that x = 2/3.
Substituting 2/3 for x in the first equation, we get:
2/3 + y = 5. Clear out fractions by multiplying all three terms by 3:
2 + 3y = 15, or 3y = 13. Then y = 13/3, and the solution is
(2/3, 13/3) There is exactly one solution.
