Multiply the entire bottom eqn by 3 to get -3x + 9y = -15.
Add the two eqns together to cancel the x's and you get 11y = -11
Solve for y to get y = -1
Pick one of the two original eqns and plug y back in:
-x + 3(-1) = -5; simplify:
-x -3 = -5
-x = -2
x = 2
So your answer is (2, -1).

Answer:
- <u>You are right, the coordinates are</u>:
Explanation:
Here is how you can proove that you are right.
Note that m is the x-coordinate of the point . Since this point is to the left of the y-axis, it is a negative number, but the negative sign is included in .
The distance from to the y-axis is not but .
That is the same distance from the point with the missing coordinates to the point (h,0).
Then, the missing x-coordinate is
Of course, there is not doubt about the y-coordinate: it is n, because the point with the missing coordinates is at the same height as (m,n).
Hence, the missing coordinates are x = h+m, and y = n: (h + m, n).
Answer:A gaming store can sell at most $3400 worth of games and controllers per day. Each game costs $40 and each controller costs $65. The store can ship a maximum of 20 items per day. Write a system of linear inequalities to represent this scenario.
