Mathematics
1 answer:
Nuetrik [128]3 years ago
8 0

Answer:

The second, and fourth choices are true.

Step-by-step explanation:

The symbol <  means less than  so the arrow will point to the LEFT.

Also -1/4 will not be a part of the solution. because the sign is less than.

Because the inequality is less than there will be an open circle at -1/4.

VERY URGENT HAVE A TEST TO TAKE
Daniel [21]
The easiest way is to try the point (-4,1), that is, x=-4, y=1,
to see which equation works.
b works.

The usual way to do it is to find the equation of the circle
standard form of a circle is (x-h)²+(y-k)²=r², (h,k) are the coordinates of the center, r is the radius. 
in this case, the center is (-2,1), so (x+2)²+(y-1)²=r²
the given point (-4,1) is for you to find r: (-4+2)²+(1-1)²=r², r=2
so the equation is (x+2)²+(y-1)²=2² 
expand it: x²+4x+4+y²-2y+1=4
x²+y²+4x-2y+1=0, which is answer b.
