2x - 4y = 10
7x - 9y = 12
_________
9x - 5y = 2
Y/x = 5 bc in order to isolate the variables you must divide by x on both sides to separate the 5, leaving you with y/x=5
Find and graph the feasible region for the following constraints: x + y < 5. 2x<span> + y > 4 ... y = 10/3. x = 30/3 - 10/3 = 20/3. Intersects at (20/3, 10/3). -x + </span>2y<span> = 0. x - </span>2y = 0.
Answer: 3/2
Step-by-step explanation:
The first one: y=2x+5
X=2y+5.Then solve for y after switching x and y
X-5=2y, X-5/2=y
Since F-1= X-5/ 2, we plug the value of X in
8-5/2, so it should be 3/2
(1,-2) im pretty sure is the answer
