A quadrilateral has vertices at (1.4). (7,3), (3, -5), and (8,4). The
quadrilateral is dilated by a scale
factor of 3.5 with the origin as its
center. What are the coordinates of
the vertices of the image of the
quadrilateral?

a) (3, 12), (21, 9), (9, -15), (24, -12)

b) (3.5, 12), (24.5, 9), (10.5, -15), (28.5, -12)

c) (3.5, 14), (24.5, 10.5), (10.5, -17.5), (28, -14)

d) (3, 14), (21, 10.5), (9, -17.5), (24, -14)

step-by-step explanation:

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.

answer: a parabola

steps:

(x-1)(x+4)   = x(x+4) - 1(x+4) = (x^2 + 4x) - (x+4)

                = x^2 +4x -x -4   = x^2 +3x -4

which is a parabola
