Answer:
Directly proportional relationships always pass through the origin (0,0). There are other linear relationships that do not pass through the origin.
The answer to this is question is C
Answer:
13.31 x 
Step-by-step explanation:
So, if we take the two equations, and add the normal numbers together, we have: 5.97 + 7.34 = 13.31
Then if we add the two tens together it would be: 
+ 
= 10 to the power of 46.
The equation would be 13.31 x
I'm not an expert, so sorry if this is wrong.
Because of exterior angles theorem, y=39+65, so y=104
x and y are a linear pair, so they add up to 180. x=180-104, x=76
all angles in a triangle add up to 180, so 21+104+z=180. therefore, z=55
y=104
x=76
z=55
