4xy^2 is the gcf, as the largest thing 20x2y4 can divide by is 4xy2
Supplementary means 180
180-32=148 hope this helps
It can’t be simplified more
Answer:
B
Step-by-step explanation:
if you look at it, it increases up to -4, and then it also decreases at -4 because it's the same line. I'm really bad at explaining so I'm sorry if this doesn't make sense.
Any multiple of (-2x+3y=18) would constitute an "other equation" forming a system with an infiinite number of solutions. The reason for that is that the two equations would be "dependent."
On the other hand, looking at the system
<span>-2x+ 3y= 18
</span><span>-2x+ 3y= 19
we see that there is no solution. Why? Because -2x + 3y cannot equal 18 and 19 at the same time. You'd have two non-intersecting, parallel lines.
