Which is the graph of the linear equality 2x-3y<12
1 answer:
Answer:
The graph below shows the answer to
2x - 3y < 12
Also shown as
-3y < -2x + 12
Step-by-step explanation:
You can rearrange the inequality by subtracting 2x from both sides to isolate the y.
You now have -3y < 12 -2x
which can be put into the standard linear equation form of
-3y < -2x + 12
Then you divide both sides by -3 to get singular value of y, which is something like
-3/-3y < -2/-3x + 12/-3
which is
y > 2/3x -4
Note: I switched direction of the inequality because you are dividing both sides by a negative value.

Answer:
The solution to the system of equations be:
- x = 3
- y = 9
Step-by-step explanation:
Given the system of equations
x + y = 12
-x + 2y = 15
Let us solve the system of equations by elimination
adding the equations
solve 3y = 27 for y
divide both sides by 3
Simplify
For x+y=12 plug in y = 9
Subtract 9 from both sides
Simplify
Therefore, the solution to the system of equations be:
- x = 3
- y = 9
Given:
Bl parallel to RA.
To find:
