Answer:
If the two linear equations have the same slope, the equations represent the same line. Since a line intersects with itself everywhere, there will be an infinite number of solutions.
Answer:
(x+3)^2+(y−3)^2=9
Step-by-step explanation:
The equation for a circle is given by
(x−h)^2+(y−k)^2=r^2 where (h,k) is the center and r is the radius
(x− -3)^2+(y−3)^2=3^2
(x+3)^2+(y−3)^2=9
Answer:
C=29
Step-by-step explanation:
a^2 + b^2 = c^2
21^2 + 20^2 = c^2
441 + 400 = c^2
841 = c^2
\sqrt(841) = \squrt(c^2)
29 = c
