Question

choose the point which is a solution to the system of inequalities:

Answer 1

\[2x-3y \ge12\]
\[x+y \le7\]

Answer 2

2x - 3y >= 12
-> y = 2/3x - 4

x + y <= 7
-> y = -x + 7

graph the graphs and see where they collide

Answer 3

I did, but i keep getting different answers.

Answer 4

it's 2/3 * x -4, check if u did 2/(3x)

the answer should be (33/5, 2/5)

Answer 5

I didn't get that...

any points in the shaded area should be a right answer.

you can get the shaded area by graphing the two graphs and shade regions based on the inequalities
