Answer:
y = 
or -3.571
x = 
or 1.429
Step-by-step explanation:
x - y = 5
x = 5 + y
Solve for y:
y = -6x + 5
y = -6(5 + y) + 5 Substitute x with 5 + y
y = -6(5) - 6y + 5
y = -30 - 6y + 5
y + 6y = -30 + 5
7y = -25
y = or -3.571
Solve for x:
x = 5 + y
x = 5 + -25/7
x = or 1.429
The correct answer is B.
Any square root that is not a perfect square is irrational. Root 3 is not a perfect square and therefore, it is irrational. Note the Root 16 is a perfect suare because 4*4=16
