Answer:

x=0 y=4

Step-by-step explanation:

12x−5y=−20

y=x+4

substitute y in the first equation with x+4 (the second equation gives you the value of y straight away)

12x-5*(x+4)=-20

12x-5x-20=-20

7x=0

x=0

use this value of x in the second equation

y=0 + 4 = 4

Answer:

Neither

Not congruent because from the picture itself, the figures are in different sizes.

Not similar because:

The height ratio is not the same as the ratios of other dimensions.

1 : 4 is not similar to 6 : 12 and 4 : 8
