Answer:
step by step as explained below
Step-by-step explanation:
A) y<4x-8 is the shade area below the dotted line of y=4x-8
y≥-2/5x+5 is the shade area above the solid line y=-2/5x+5
The solution is the dark color shade area
B) point(5,-8) located within the y<4x-8 area while it's not in the solution area of the system.

Answer:
The equation of the parabolic function is :
Step-by-step explanation:
The standard equation of a parabola is given by:
where represents the vertex of the parabola.
From the graph shown in figure we can find the vertex of the parabola which is the minimum point of parabola and lies st point
So, we can say:
Plugging in the values of vertex in standard equation of parabola,
Simplifying the equation:
We can find value of by plugging in a point from the graph.
Using point (0,-2) which lies on graph.
Plugging in the given point.
Adding 3 to both sides.
∴
Plugging in , the equation of parabola can be written as:
