If ABCDE is reflected over the x-axis and then translated 3 units left, what are
the new coordinates D?

O A. (3,0)
O B. (-6,1)
O C. (0,1)
O D. (1,0)

idk

step-by-step explanation:

use that smart brain

the discriminant is 64 + 4*1*12 = 112

this is prime.

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
