The equation that best represent the actual prices of the skis is,
I x - 500 I ≥ 250
Solving the absolute value equation,
x ≤ 750 and x ≥ 250
Thus, the prices of the skis ranges from 250 to 750.
f (x) = a(x - h)2 + k, where (h, k) is the vertex of the parabola. FYI: Different textbooks have different interpretations of the reference "standard form" of a quadratic function.
The standard form of a parabola is y=ax2++bx+c , where a≠0 . The vertex is the minimum or maximum point of a parabola. If a>0 , the vertex is the minimum point and the parabola opens upward. If a<0 , the vertex is the maximum point and the parabola opens downward.
Well 2.5 + 2.5 is 5 so 5 - 2.5 is 2.5
Answer:

Step-by-step explanation:
Area of parallelogram =base x height
Area=20 x 8=160
Units=

Divide both sides by -5 to get x= -13
