The red area is the one which solves the system. In fact, we want the area which below both the parabola and the line (since the inequality features a 
sign.
So, the point 
is below the line but above the parabola (blue area), so it is not a solution.
The point 
is above both the line and the parabola (white area), so it is not a solution.
The point 
is below both the line and the parabola (red area), so it is a solution.
So, the point 
is below the parabola but above the line (green area), so it is not a solution.
Answer:288
Step-by-step explanation:
Delta math
Answer:
(8,-3)
Step-by-step explanation:
(x1+x2/2), (y1+y2/2)
7+9/2=16/2=8 x=8
-5-1/2=-6/2=-3 y=-3
Answer:
(1) let pen = x
let pencil= y
i) y ≤ 5x
ii) 5x + 2y ≤ 40
Step-by-step explanation:
at most = maximum
None of the above because it would be 2x+y
