1 Dilate line f by a scale factor of with the center of dilation at the origin to create line f. Where are points A and B located after dilation, and how are lines f and f related?
2
O The locations of A and B' are A' (0, 2) and B' 0, 0); lines f and f intersect at point A.
The locations of A and B' are A (0, 1) and B (1,0); lines f and I are parallel.
The locations of A and B' are A' (0,0) and B (2, 0); lines f and f intersect at point B.
The locations of A and B' are A' (0, 2) and B' (2, 0); lines fand f are the same line.

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
