Answer:
(-2,-3)
Step-by-step explanation:
Put the equations over each other.
Subtract the x values.
Subtract on both sides.
Divide on both sides.
Insert the y value into one of the equations.
Get rid of the parenthesis.
Subtract on both sides.
<em>You</em><em> </em><em>could</em><em> </em><em>also</em><em> </em><em>individually</em><em> </em><em>plug</em><em> </em><em>in</em><em> </em><em>each</em><em> </em><em>solution</em><em> </em><em>into</em><em> </em><em>both</em><em> </em><em>equations</em><em> </em><em>to</em><em> </em><em>see</em><em> </em><em>if</em><em> </em><em>they</em><em> </em><em>are</em><em> </em><em>true</em><em>.</em>

Answer:
- n = (s/m) -r
- n = (s -mr)/m
Step-by-step explanation:
1. Undo the operations done to n, in reverse order. Here, n has r added and the sum is multiplied by m. First we divide by m, then we subtract r.
m(n+r) = s . . . given
n +r = s/m . . . divide by m
n = (s/m) -r . . . subtract r
__
2. Eliminate the parentheses, then proceed as above. Subtract the added term, then divide by the coefficient of n.
m(n+r) = s
mn +mr = s . . . eliminate parentheses
mn = s -mr . . . subtract the added term
n = (s -mr)/m . . . divide by the coefficient of n
Step-by-step explanation:
The general form of an equation of a circle with center at (a, b) and radius r is given as:
(x - a)² + (y - b)² = r²
There is no images available to help decide which circle is the right choice... But with the knowledge of what a standard circle looks like, we can make the choice.
