Lyle graphs triangle ABC on coordinate axes. He performs two transformations on this figure that result in the congruent triangle XYZ. Which series of transformations did Lyle most likely use? A. a translation left and then a dilation with a scale factor of 3

B. a dilation with a scale factor of 2.5 and then a rotation 180˚ counterclockwise

C. a rotation 90˚ clockwise and then a reflection across the y-axis

D. a reflection across the x-axis and then a dilation with a scale factor of 0.25

Step-by-step explanation:

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
