Well, notice the graph, the center is clearly not at the origin.
well, the major axis is horizontal, notice the distance from the center to a vertex, is 4 units, and the major axis is 2a, namely 2(4).
the foci are the points at "c" distance from the center of the ellipse over the major axis, hmmmm what is "c" anyway?
the directrices are lines parallel with the minor axis, and away from the vertices, in this case they're be two vertical lines.

Answer:
W=191,000MWH S=27,000MWH
Step-by-step explanation:
OK, let's W be wind electricity generated and S, solar electricity generate.
TOTAL GENERATED: 218,000mwh = W + S
RELATION BETWEEN W AND S: W = 2,000mwh + 7S
We have now two equations:
218,000 = W + S
W = 2,000 + 7S
Put th value of W into the 1st equation in order to find S:
218,000 = 2,000 + 7S + S
218,000 = 2,000 + 8S
218,000 - 2,000 = 8S
216,000 = 8S
S = 216,000/8
S = 27,000mwh
Now, we find W.
W = 2,000 + 7*27,000mwh
W = 2,000 + 189,000mwh
W = 191,000mwh
