Answer:
coincident
Step-by-step explanation:
The first equation is 3 times the second equation, so describes exactly the same line. The lines are "coincident".
Answer:
y-2x=8 (label equation 1)
16+4x=2y (label equation 2)
divide equation 2 by 2 to find y
y=2x+8
sub this in equation 1
(2x+8)-2x=8
2x+8-2x=8
8=8
once you get to this point because 8=8 there are an infinite number of solutions because you can't divide by 0. So the answer is B
Answer:
4(9x^4+1858)
Step-by-step explanation:
36 x^4 + 18^3 + 40^2
36x^4+7432
4(9x^4+1858)
Answer:
-142
Step-by-step explanation:
First solve parenthesis,
(12) - (23 +131) =
(12) -154
Finally subtract,
12-154
= -142
