The figure shows two similar triangles on a coordinate grid:
which set of transformations have been performed on triangle abc to form triangle a'b'c'?
a.)dilation by a scale factor of 2 followed by reflection about the x-axis
b.)dilation by a scale factor of 4 followed by reflection about the x-axis
c.)dilation by a scale factor of 2 followed by reflection about the y-axis
d.)dilation by a scale factor of 4 followed by reflection about the y-axis

C. Dilation by a scale factor of 2 followed by reflection about the y-axis

Step-by-step explanation:

You are given triangle with vertices A(1,2), B(0,0) and C(3,-1).

1. Dilation by a factor of 2 has the rule:

(x,y)→(2x,2y)

So,

2. Reflection about the y-axis has the rule:

(x,y)→(-x,y)

So,

Points A', B' and C' are exactly vertices of the triangle A'B'C' shown in the diagram.

4 candies

step-by-step explanation:

7 x 28 = 196

200 - 196 = 4 candies remaining.
