First, find the difference between $130 and $104. This equals $26, and to find this discount written as a percent, divide $26 by the original cost of the camera. 26/130=0.2, which represents a 20% discount.
Answer:
Step-by-step explanation:
Here the coefficients of this quadratic are a = 1, b = 6 and c = 4.
-b
The axis of symmetry is x = -------- , which here is x = -6/2, or x = - 3.
2a
Use the given quadratic to find the vertical coordinate of the vertex:
y = (-3)^2 + 6(-3) + 4 = 9 - 18 + 4 = y = -5.
The axis of symmetry is x = -3, and the vertex is (-3, -5).
