Quickly please Choose an equivalent system of equations to the following system:

Fx + Gy = H
Qx + Ry = S

5Fx + 5Gy = 5H
Qx − Ry = S
5Fx + Gy = 5H
Qx + 5Ry = S
5Fx + 5Gy = 5H
Qx + Ry = S
Fx + 5Gy = 5H
Qx + Ry = S

First locate the turning point (vertex) of the graph. which is at the coordinates x=5 and y=9 or (5; 9).to determine whether it's a maximum or mininum value, you have to discern whether the vertex's y-value is the highest value or lowest value the graph can reach. since the vertex's y-value, 9 is the highest value the graph can reach, it will be a maximum.another basic way to determine whether the vertex's value is max or min is to see if the graph is smiling or sad. if it's smiling, the turning point/vertex would be a minimum, while a sad parabola would have a maximum y-value at the vertex.
