Answer:
Center:-1,-2
Radius: 2
Step-by-step explanation:
Ok, get the form of a circle from this equation-
(x+2)^2+(y+2)^2=4
Since this is the form of a circle, I can figure out the center and the radius from here,
r=2
h=-1
k=-2
Center:-1,-2
Radius: 2
The system of equation that has one solution is: (d) –2x+ 7y = –5 and 2x +7y = –9
<h3>What are systems of equations?</h3>
This is a group of equations which may have none, one or more solutions.
From the list of given options, the system of equations that has one solution is:
–2x+ 7y = –5 and 2x +7y = –9
This is so because, the solution is (-1,-1)
However, the other systems have infinite many solutions

We know that the angle at the top of the triangle is 90 degrees by definition
<span>(Angle in the Semicircle Theorem</span>). That makes angle y 45 degrees (as is the angle opposite y). The angle next to 82 degrees is supplementary and therefore is 98 degrees. Since we know we have 98, and 45 degree angles in the triangle already, x must be 37. Since the triangle must have 180 degrees.
Y = 45
X = 37
Answer:
1.35 about 6 quarters
Step-by-step explanation:
2.75-1.35=1.40
1.40/0.25=about 6
