Describe the graph that is produced by the equation (x-7)^2+(y+5)^2>25

Sagot :

Step-by-step explanation:

The equation will form a circle because it in the form of

[tex](x - h) {}^{2} + (y - k) {}^{2} = {r}^{2} [/tex]

First, let set the equation equal.

[tex](x - 7) {}^{2} + (y + 5) {}^{2} = 25[/tex]

Here the center will be (7,-5), and the radius of 5. The boundary line will be dashed

Since this is in the inequalities, we must find the solution set.

Plug in 0,0 for x and y and see if it's true.

[tex](0 - 7) {}^{2} + (0 + 5) {}^{2} > 25[/tex]

[tex]49 + 25 > 25[/tex]

[tex]74 > 25[/tex]

This is a true so we shade the region that includes 0,0

Since 0,0 has a greater distance from the center of the circle, 0,0 is outside of the circle, so our solution set will

be outside of circle.
