2x + y - 4 = 0.....2x + y = 4
2x - y - 4 = 0.....2x - y = 4

2x + y = 4
2x - y = 4
--------------add
4x = 8
x = 8/4
x = 2

2x + y = 4
2(2) + y = 4
4 + y = 4
y = 4 - 4
y = 0

solution is (2,0)

Marco picked answer A for the following problem. Why is that not the correct answer? (NO LINKS)
ICE Princess25 [194]

Answer:

This is not correct because the organic rice line in Graph A is increasing more than the conventional rice line. This is why the x- and y-labels are important: organic rice in Graph A; you are able to get more pounds for the same amount of weight. If organic rice costs more, you should get less pounds of rice. Graph B shows this relationship because the conventional rice line is higher than the orangic rice line, which indicates that you can get more conventional rice than organic rice at the same price, which is what the question says.

(A3- 2a2) - ( 3a2- 4a3)
Tanzania [10]
If you would like to calculate (a^3 - 2 * a^2) - (3 * a^2 - 4 * a^3), you can do this using the following steps:

(a^3 - 2 * a^2) - (3 * a^2 - 4 * a^3) = a^3 - 2 * a^2 - 3 * a^2 + 4 * a^3 = 5 * a^3 - 5 * a^2

The correct result would be 5 * a^3 - 5 * a^2.
