Answer:
(x, y) = (-6, -4)
Step-by-step explanation:
The solution can be found quickly using a graphing calculator. It is the point of intersection of the two lines.
_____
If you like, you can solve the system algebraically. The second equation can be rewritten to give ...
y = x +2
Substituting this into the first equation gives ...
5/3x -2(x +2) = -2
-1/3x -4 = -2
Adding 4 and multiplying by -3 gives ...
x = -3(-2+4) = -6
Then our equation for y tells us ...
y = -6 +2 = -4
The solution is (x, y) = (-6, -4).
40 tens is another way of writing 4 hundreds because 40 tens would give you 400 and 4 hundreds also give you 400.
Answer:
(-2, 1).
Step-by-step explanation:
When f(x) = 0
4 + 2x = 0
2x = -4
x = -2.
Ehen f(x) = 6
4 + 2x = 6
2x = 6-4 = 2
x = 1.
