Answer:
x = -4 , y = 3
Step-by-step explanation:
5x - 7y = -41 ... (i)
-3x - 5y = -3 ... (ii)
Multiplying (i) by -3 and (ii) by 5 ;
-15x + 21y = 123 ... (i)
-15x - 25y = -15 ... (ii)
Subtracting (i) by (ii) ;
0 + 46y = 138
46y = 138
y = 138 ÷ 46 = 3
Returning to equation (ii) ;
-3x - 5(3) = -3
-3x = -3 + 15
-3x = 12
x = -4

Answer:
Option D is correct.
Step-by-step explanation:
Given that
A ray is a defined term we have to give the reason of the above statement.
A ray is a line or a part of a line that has one endpoint which we defined and other goes on infinitely in only one direction.
One of the example is a sun's ray of light in space. Light from the sun originates and travels from the sun, and its path extends infinitely.\
Hence, we say that "A ray is a defined term because it travels forever in one direction"
Option D is correct.
