3/4 + (1/3 divided by 1/6) - ( -1/2)

3 1/4

Step-by-step explanation:

3/4 + (1/3÷1/6) - (-1/2)

3/4 + (6/3) - (-1/2)

3/4 + 2 + 1/2

3/4 + 8/4 + 2/4

13/4

3 1/4

Step-by-step explanation:

Right triangle ABC is reflected over AC to form triangle AFC.

Triangle AFC dilated by a scale factor of two-thirds to form triangle DEC.

Reflection is a rigid transformation which preserves lengths and angles, then

Dilation is a transformation which maps the triangle into similar triangle, so

Thus,

Similar triangle have congruent corresponding angles, so

and proportional corresponding sides

Thus, correct options are:
