Image RSTU has the following vertices - R(-4, 0), S(-4, 1), T(0, 1), U(-3, -3). The image is reflected across the x-axis. is What are the vertices of the reflected image? A
S'(4, 1), T'(0, 1), U'(3, -3), R'(4, 0)

B
R'(-2, 2), S'(-2, 3), T'(2, 3), U'(-1, -1)

C
S'(-4, -1), T'(0, -1), U'(-3, 3), R'(-4, 0)

D
R'(-4, -1), S'(-4, 0), T'(0, 0), U'(-3, -4)

the answer is 62

36

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
