this is system of equations
2x + 5y = -1 times this one by 5 to make the y's opposite
-10x -25y = 5
10x - 25y = -5 (this is it times by 5, now add them)
__________
0 + 0 = 0
now since everything cancels and both sides are equal it has infinite solutions beaus they are actually the same line.
Answer:
30.5
Step-by-step explanation:
45.2216762184
It is the square root of
405x5
The general equation for a circle with center (a,b) and squared radius k is

Here we have

and the constant is fixed by substituting in the point we know (x,y)=(3,-5)

Answer:

Answer:
$50.00
