Trapezoid DEFG is dilated according to the rule DO,4(x, y) to form the image trapezoid D'E'F'G', which is shown on the graph. On a coordinate plane, trapezoid D prime E prime F prime G prime has points (negative 8, 8), (negative 3, 8), (negative 5, 4), and (negative 8, 4). What are the coordinates of point G of the pre-image? (-2, 1) (-4, 2) (-12, 0)

Exercise: counting committees 0.0/2.0 puntos (calificable) we start with a pool of n people. a chaired committee consists of k≥1 members, out of whom one member is designated as the chairperson. the expression k(nk) can be interpreted as the number of possible chaired committees with k members. this is because we have (nk) choices for the k members, and once the members are chosen, there are then k choices for the chairperson. thus, c=∑k=1nk(nk) is the total number of possible chaired committees of any size. find the value of c (as a function of n ) by thinking about a different way of forming a chaired committee: first choose the chairperson, then choose the other members of the committee. the answer is of the form c=(α+nβ)2γn+δ. what are the values of α , β , γ , and δ ?
