Which points satisfy the following system of linear inequalities? Show all your work. -5y+4x<18 -15y-9x>117
raketka [301]
The lines intersect on the graph at (-3, -6).  The solution set falls within the domain of negative infinity to positive infinity and a range of y is greater than or equal to -6.  Without having the capabilities of graphing it to show you, that's the best I can do. Graph the lines (dotted, I presume) and see if you can follow those guidelines for the solution set.

PLEASE HELP<br><br> Identify the radius and center <br><br><br>x^2 +y^2 -6x -2y + 1 = 0
Trava [24]

Answer:

The center is the point (3,1) and the radius is 3 units

Step-by-step explanation:

we know that

The equation of a circle in standard form is equal to

(x-h)^{2}+(y-k)^{2}=r^{2}

we have

x^{2}+y^{2}-6x-2y+1=0

Convert to standard form

Group terms that contain the same variable, and move the constant to the opposite side of the equation

(x^{2}-6x)+(y^{2}-2y)=-1

Complete the square twice. Remember to balance the equation by adding the same constants to each side.

(x^{2}-6x+9)+(y^{2}-2y+1)=-1+9+1

(x^{2}-6x+9)+(y^{2}-2y+1)=9

Rewrite as perfect squares

(x-3)^{2}+(y-1)^{2}=9

The center is the point (3,1) and the radius is 3 units
