Triangle abc with vertices a(4, -6), b(2, -8), and c(-10, 4) is dilated by a scale factor of 2 to obtain triangle a'b'c which statement best describes triangle a'b'c it is similar to triangle abc and has coordinates a'(2,-3), b'(1,-4), and c'(-5, 2). it is similar to triangle abc and has coordinates a'(8,-12). b'(4, -16), and c'(-20, 8). it is congruent to triangle abc and has coordinates a'(2, -3), b'(1,-4), and c'(-5, 2). it is congruent to triangle abc and has coordinates a'(8, -12), b'(4,-16), and c'(-20, 8).

  It is similar to triangle ABC and has coordinates A'(8,-12). B'(4, -16), and C'(-20, 8).

Step-by-step explanation:

Dilation about the origin multiplies each coordinate value by the dilation factor:

  A' = 2A = 2(4, -6) = (8, -12) . . . . A' for example

Dilated figures cannot be congruent if the dilation factor is not 1. They are always similar.

The appropriate description is the one shown above.

the answer is d

step-by-step explanation:

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
