What is the center of the circle given by the equation (x-2)^2 + (y+4)^2 = 6
Kay [80]
The equation of circle with center (g,f) and radius r is given by,
(x-g)² + (y-f)² = r²

Now, compare equation (x-2)² + (y+4)² = 6 with the above equation.
g = 2 and f = -4
Therefore, center of the circle is (2,-4)

The system of equations below is consistents with infinity many solutions where a and b are constants.Find the values of a and b
Kitty [74]

Answer:

The values of a and b so that the two linear equations have infinite solutions are 3 and \frac{3}{2}, respectively.

Step-by-step explanation:

Two linear equations with two variables have infinite solution if and only if they are<em> linearly dependent</em>. That is, one linear equation is a multiple of the other one. Let be the following system of linear equations:

2\cdot x + y = 6 (1)

a\cdot x + b\cdot y = 9 (2)

The following condition must be observed:

r = \frac{a}{2} = \frac{b}{1} = \frac{9}{6} (3)

After some quick operations, we find the following information:

r = \frac{3}{2}, a = 3, b = \frac{3}{2}

The values of a and b so that the two linear equations have infinite solutions are 3 and \frac{3}{2}, respectively.
