You are almost done!
well, the euation of a circle centered at (h,k) and radius r is
(x-h)²+(y-k)²=r²

so you havve
(x-3)²+(y+5)²=9 (which is correct)
this can be rewritten as
(x-3)²+(y-(-5))²=3²
the center is (3,-5) and the radius is 3

What is the value of z so that-9 and 9 are both solutions of x^2+z=103?
notka56 [123]
If the sol'ns are -9 and 9, then we can use this to form our eq'n:
(x - 9)(x + 9) = 0
x^2 - 81 = 0
so...
x^2 + z - 103 = x^2 -81
z - 103 = -81
z = -81 + 103
z = 22

4. find the value of ‘k’ for which 2x 3y = 4 and (k 2) x 6y = 3k 2 has a infinitely many solutions.
Lana71 [14]

For the given system of linear equations to give an infinite number of solutions the value of k should be 2.

<h3>What is a Dependent Consistent System of equations?</h3>

A system of the equation to be a Dependent Consistent System the system must have multiple solutions for which the lines of the equation must be coinciding.

Given the two systems of linear equations,

2x + 3y = 4

(k+ 2)x + 6y = 3k+2

For any system of equations to have infinitely many solutions, the equation of the linear system must be in ratio, so that the lines of the equations overlap each other. Therefore, the ratio for the two of the given equations can be written as,

2/(k+2) = 3/6 = 4/(3k+2)

Solving the ratio to get the value of k,

2/(k+2) = 3/6

2/(k+2) = 1/2

2 × 2 = 1 × (k+2)

4 = k + 2

4 - 2 = k

k = 2

Hence, for the given system of linear equations to give an infinite number of solutions the value of k should be 2.
